ASAuthorizationProviderExtensionAuthorizationRequest.complete(httpAuthorizationHeaders:) custom header not reaching endpoint
I’m implementing a macOS Platform SSO extension using ASAuthorizationProviderExtensionAuthorizationRequest. In beginAuthorization, I intercept an OAuth authorize request and call: request.complete(httpAuthorizationHeaders: [ "x-psso-attestation": signedJWT ]) I also tested: request.complete(httpAuthorizationHeaders: [ "Authorization": "Bearer test-value" ]) From extension logs, I can confirm the request is intercepted correctly and the header dictionary passed into complete(httpAuthorizationHeaders:) contains the expected values. However: the header is not visible in browser devtools the header does not appear at the server / reverse proxy So the question is: Does complete(httpAuthorizationHeaders:) support arbitrary custom headers, or only a restricted set of authorization-related headers ? Is there something that I might be missing ? And if custom headers are not supported, is there any supported way for a Platform SSO extension to attach a normal HTTP header to the continued outbound request ?

Issue to reset "Privacy & Security" permissions
Hello, I am working on a script to update an application which bundle ID changed. Only the bundle ID was modified; all other aspects remain unchanged. This application requires access to "Screen & System Audio Recording" permissions, which are currently granted to the old bundle ID. The script performs the following steps: launchctl bootout gui/$(id -u) /Library/LaunchAgents/com.my_agent_1.plist pkgutil --forget com.my_agent_1 tccutil reset All com.my_agent_1 rm /Library/LaunchAgents/com.my_agent_1.plist rm -rf </path/to/com_my_agent_1> installer -dumplog -allowUntrusted -pkg </path/to/com_my_agent_2.pkg> -target / ... When running steps #1-6 without a restart between steps #5 and #6, the old bundle ID (com.my_agent_1) remains visible in TCC.db (verified via SQL queries). Looks like this is the reason why "com.my_agent_2" is not automatically added to the permission list (requiring manual add). Moreover, "tccutil reset All com.my_agent_1" does not work anymore, the error: tccutil: No such bundle identifier "com.my_agent_1": The operation couldn’t be completed. (OSStatus error -10814.) Is there any way to completely clear the "Privacy & Security" permissions without requiring a system restart? Thank you a lot for your help in advance!

Exploring Secure Enclave–backed biometric authorization between macOS and iPhone using public APIs (FaceBridge prototype)
Hi everyone, I’ve been working on an experimental prototype called FaceBridge that explores whether Secure Enclave–backed biometric authorization can be delegated between macOS and iPhone using only public Apple APIs. The goal of the project was to better understand the architectural boundaries of cross-device trust and approval flows that resemble Apple’s built-in Touch ID / Continuity authorization experiences. FaceBridge implements a local authorization pipeline where: macOS generates a signed authorization request the request is delivered to a trusted nearby iPhone over BLE / Network framework the iPhone verifies sender identity Face ID approval is requested using LocalAuthentication the iPhone signs the approval response using Secure Enclave–backed keys macOS validates the response and unlocks a protected action Security properties currently implemented: • Secure Enclave–backed signing identities per device • cryptographic device pairing and trust persistence • replay protection using nonce + timestamp binding • structured authorization request/response envelopes • signed responder identity verification • trusted-device registry model • local encrypted transport over BLE and local network This is intentionally not attempting to intercept or replace system-level Touch ID dialogs (App Store installs, Keychain prompts, loginwindow, etc.), but instead explores what is possible within application-level authorization boundaries using public APIs only. The project is open source: https://github.com/wesleysfavarin/facebridge Technical architecture write-up: https://medium.com/@wesleysfavarin/facebridge I’m particularly interested in feedback around: • recommended Secure Enclave identity lifecycle patterns • best practices for cross-device trust persistence • LocalAuthentication usage in delegated approval scenarios • whether similar authorization models are expected to become more formally supported across Apple platforms in the future Thanks in advance for any guidance or suggestions.

Problem Saving a ASPasskeyCredentialIdentity
Hi I'm developing an app that autofills Passkeys. The app allows the user to authenticate to their IdP to obtain an access token. Using the token the app fetches from <server>/attestation/options. The app will generate a Passkey credential using a home-grown module - the extension has no involvement, neither does ASAuthorizationSecurityKeyPublicKeyCredentialProvider. I can confirm the passkey does get created. Next the credential is posted to <server>/attestation/results with the response JSON being parsed and used to create a ASPasskeyCredentialIdentity - a sample of the response JSON is attached. Here is my save function: static func save(authenticator: AuthenticatorInfo) async throws { guard let credentialID = Data(base64URLEncoded: authenticator.attributes.credentialId) else { throw AuthenticatorError.invalidEncoding("Credential ID is not a valid Base64URL string.") } guard let userHandle = authenticator.userId.data(using: .utf8) else { throw AuthenticatorError.invalidEncoding("User handle is not a valid UTF-8 string.") } let identity = ASPasskeyCredentialIdentity( relyingPartyIdentifier: authenticator.attributes.rpId, userName: authenticator.userId, // This is what the user sees in the UI credentialID: credentialID, userHandle: userHandle, recordIdentifier: authenticator.id ) try await ASCredentialIdentityStore.shared.saveCredentialIdentities([identity]) } Although no error occurs, I don't get any identities returned when I call this method: let identities = await ASCredentialIdentityStore.shared.credentialIdentities( forService: nil, credentialIdentityTypes: [.passkey] ) Here is the Info.plist in the Extension: <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>ASCredentialProviderExtensionCapabilities</key> <dict> <key>ProvidesPasskeys</key> <true/> </dict> <key>ASCredentialProviderExtensionShowsConfigurationUI</key> <true/> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.authentication-services-credential-provider-ui</string> <key>NSExtensionPrincipalClass</key> <string>$(PRODUCT_MODULE_NAME).CredentialProviderViewController</string> </dict> </dict> </plist> The entitlements are valid and the app and extension both support the same group. I'm stumped as to why the identity is not getting saved. Any ideas and not getting retrieved. attestationResult.json

Conditional create on iPhone + Safari + Passwords violates the WebAuthn spec
WebAuthn Level 3 § 5.1.3 Step 22 Item 4 states the steps a user agent MUST follow when "conditional" mediation is used in conjunction with required user verification: Let userVerification be the effective user verification requirement for credential creation, a Boolean value, as follows. If pkOptions.authenticatorSelection.userVerification is set to required If options.mediation is set to conditional and user verification cannot be collected during the ceremony, throw a ConstraintError DOMException. Let userVerification be true. On my iPhone 15 Pro Max running iOS 18.5, Safari + Passwords does not exhibit this behavior; instead an error is not reported and user verification is not performed (i.e., the UV bit is 0). Per the spec this results in a registration ceremony failure on the server which is made all the more "annoying" since the credential was created in Passwords forcing a user to then delete the credential. : If the Relying Party requires user verification for this registration, verify that the UV bit of the flags in authData is set. In contrast when I use Google Password Manager + Chrome on a Samsung Galaxy S24 running Android 15, user verification is enforced and the UV bit is 1. Either the UV bit should be 1 after enforcing user verification or an error should be thrown since user verification cannot be performed.

com.apple.developer.web-browser.public-key-credential still leads to com.apple.AuthenticationServices.AuthorizationError Code=1004
Hi, we were recently approved for the com.apple.developer.web-browser.public-key-credential entitlement and have added it to our app. It initially worked as expected for a couple of days, but then it stopped working. We're now seeing the same error as before adding the entitlement: Told not to present authorization sheet: Error Domain=com.apple.AuthenticationServicesCore.AuthorizationError Code=1 "(null)" ASAuthorizationController credential request failed with error: Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1004 "(null)" Do you have any insights into what might be causing this issue? Thank you!

Developing Platform SSO extension
Hi, I am developing a Platform SSO in order to have integrated with our IdP, which I am also adapting to provide the right endpoints for Platform SSO. I have a few questions about the implementation: does the client-request-id need to be present on all requests? Is it unique per request, or requests that are bound together like those requesting a nonce and those who will use that nonce should use the same client-request-id? I am not sure how the loginManager.presentRegistrationViewController works. I'd like to get the user to authenticate to my IdP before device registration. So I am not sure if I should provide my own Webview or something similar or if this method should do something for me; My idea is to request user authentication once, save the state when performing device registration, so that I avoid asking for user authentication twice when performing user registration. Is this the right way to do it? How does platform SSO handles tokens? If one application of my IdP requests the authentication on a common OIDC/OAuth2 flow, should I perform some sort of token exchange? How about SAML? Platform SSO seems to be token-centric, but how does one handle SAML flows? Is it by using WebView as well?

email sent to to an iCloud account is landed to junk when email sent from user-*dev*.company.com micro service
Our company has a micro service which sends a notification email to an iCloud account/email and the email is going to the junk folder. As we tested, the email generated from user-field.company.com goes to the Inbox, while the email from user-dev.company.com goes to the Junk folder. Is there a way to avoid sending the emails to client's Junk folder when the email is sent from a specific company domain?

Control over "\(your_app) wants to open \(another_app)" Dialog
I can't find any information about why this is happening, nor can I reproduce the 'successful' state on this device. My team needs to understand this behavior, so any insight would be greatly appreciated! The expected behavior: If I delete both apps and reinstall them, attempting to open the second app from my app should trigger the system confirmation dialog. The specifics: I'm using the MSAL library. It navigates the user to the Microsoft Authenticator app and then returns to my app. However, even after resetting the phone and reinstalling both apps, the dialog never shows up (it just opens the app directly). Does anyone know the logic behind how iOS handles these prompts or why it might be persistent even after a reset? Thanks in advance!

ASWebAuthenticationSession: Form submit fails on TestFlight unless submitted through Keychain autofill
I'm experiencing a strange issue where ASWebAuthenticationSession works perfectly when running from Xcode (both Debug and Release), but fails on TestFlight builds. The setup: iOS app using ASWebAuthenticationSession for OIDC login (Keycloak) Custom URL scheme callback (myapp://) prefersEphemeralWebBrowserSession = false The issue: When using iOS Keychain autofill (with Face ID/Touch ID or normal iphone pw, that auto-submits the form) -> works perfectly When manually typing credentials and clicking the login button -> fails with white screen When it fails, the form POST from Keycloak back to my server (/signin-oidc) never reaches the server at all. The authentication session just shows a white screen. Reproduced on: Multiple devices (iPhone 15 Pro, etc.) iOS 18.x Xcode 16.x Multiple TestFlight testers confirmed same behavior What I've tried: Clearing Safari cookies/data prefersEphemeralWebBrowserSession = true and false Different SameSite cookie policies on server Verified custom URL scheme is registered and works (testing myapp://test in Safari opens the app) Why custom URL scheme instead of Universal Links: We couldn't get Universal Links to trigger from a js redirect (window.location.href) within ASWebAuthenticationSession. Only custom URL schemes seemed to be intercepted. If there's a way to make Universal Links work in this context, without a manual user-interaction we'd be happy to try. iOS Keychain autofill works The only working path is iOS Keychain autofill that requires iphone-authentication and auto-submits the form. Any manual form submission fails, but only on TestFlight - not Xcode builds. Has anyone encountered this or know a workaround?

Custom MFA Authorization Plugin XIB Window Lacks Focus during reboot on macOS
I have enabled FileVault on macOS having a custom authorisation plugin , which will load our multi-factor authentication (MFA) window . This third-party custom authorisation plugin replaced loginwindow:login mechanism from authorisation db (system.login.console) .After these changes, during reboot, we observed that the focus isnt on our custom Xib window.We noticed that the custom Xib window is rendered on a completely black background . End user has to use mouse to click on the custom Xib window, so that the textbox gains its focus. The possible solutions we have tried, Simulating mouse click Making Window to gain focus using makeKeyAndOrderFront Steps to reproduce: Enable Filevault on the machine Remove loginwindow:login and add your custom authorisation plugin in its place with a textbox to capture password 3.Perform reboot of the machine 4.The custom xib window is rendered on a black window but the window doesnt gain focus. The user has to perform a mouse click on the window to gain its focus Any help would be greatly appreciated on the above mentioned issue

App Attest Issue in Production - Attestation Object Size Increased
Hi Apple Team and Community, We encountered a sudden and widespread failure related to the App Attest service on Friday, July 25, starting at around 9:22 AM UTC. After an extended investigation, our network engineers noted that the size of the attestation objects received from the attestKey call grew in size notably starting at that time. As a result, our firewall began blocking the requests from our app made to our servers with the Base64-encoded attestation objects in the payload, as these requests began triggering our firewall's max request length rule. Could Apple engineers please confirm whether there was any change rolled out by Apple at or around that time that would cause the attestation object size to increase? Can anyone else confirm seeing this? Any insights from Apple or others would be appreciated to ensure continued stability. Thanks!

Custom right using builtin:authenticate on macOS
When implementing a custom right in macOS authorizationdb, the mechanism array element builtin:authenticate is displaying the message 'Enter the name and password of a user in the "(null)" group to allow this.' on the macOS credential prompt UI popup. I am trying to find a fix to avoid the reference to null group in the message label that is displayed just above the username and password input fields. The current plist uses class as the key and value as the evaluate-mechanisms. The mechanisms array includes mechanism array with elements "builtin:login-begin", "mycustombundle:mycustompreaction", "builtin:authenticate", "mycustombundle:mycustommechanism". I have tried specifying group in the plist, have tried setting hint in the MechanismInvoke for group, username, security, authority, prompt, reason among several other hints into the context duing the execution of mycustombundle:mycustompreaction, but none seem to fix the "(null)" in the message label. Any help is greately appreciated. There is not much of any documentation for developers implementing custom authorization in macOS.

iPhone + Safari + Passwords violates WebAuthn spec when pubKeyCredParams doesn't contain ES256
WebAuthn Level 3 § 6.3.2 Step 2 states the authenticator must : Check if at least one of the specified combinations of PublicKeyCredentialType and cryptographic parameters in credTypesAndPubKeyAlgs is supported. If not, return an error code equivalent to "NotSupportedError" and terminate the operation. On my iPhone 15 Pro Max running iOS 18.5, Safari + Passwords does not exhibit this behavior; instead an error is not reported and an ES256 credential is created when an RP passes a non-empty sequence that does not contain {"type":"public-key","alg":-7} (e.g., [{"type":"public-key","alg":-8}]). When I use Chromium 138.0.7204.92 on my laptop running Arch Linux in conjunction with the Passwords app (connected via the "hybrid" protocol), a credential is not created and instead an error is reported per the spec.

Incorrect Branding and Messaging Displayed on "Call Customer Center" Feature
We’ve identified an issue in our app where, upon clicking the "Call Customer Center" button, users are unexpectedly shown a logo and message option on a native pop-up window. However, this wasn't the case before, and it should only display a phone number to dial, which was given inside our code. This is incorrect and misleading for our users, as: We are a Canadian-based service and have no affiliation with US messaging chat. The messaging feature was never enabled or intended for our app. Our app should only initiate a phone call to our customer support center — no messages or branding from third parties should appear

Issue to reset "Privacy & Security" permissions
Hello, I am working on a script to update an application which bundle ID changed. Only the bundle ID was modified; all other aspects remain unchanged. This application requires access to "Screen & System Audio Recording" permissions, which are currently granted to the old bundle ID. The script performs the following steps: launchctl bootout gui/$(id -u) /Library/LaunchAgents/com.my_agent_1.plist pkgutil --forget com.my_agent_1 tccutil reset All com.my_agent_1 rm /Library/LaunchAgents/com.my_agent_1.plist rm -rf </path/to/com_my_agent_1> installer -dumplog -allowUntrusted -pkg </path/to/com_my_agent_2.pkg> -target / ... When running steps #1-6 without a restart between steps #5 and #6, the old bundle ID (com.my_agent_1) remains visible in TCC.db (verified via SQL queries). Looks like this is the reason why "com.my_agent_2" is not automatically added to the permission list (requiring manual add). Moreover, "tccutil reset All com.my_agent_1" does not work anymore, the error: tccutil: No such bundle identifier "com.my_agent_1": The operation couldn’t be completed. (OSStatus error -10814.) Is there any way to completely clear the "Privacy & Security" permissions without requiring a system restart? Thank you a lot for your help in advance!

DeviceCheck - Device Validation Endpoint not working
We have been having very high response times in device check device validation service (https://developer.apple.com/documentation/devicecheck/accessing-and-modifying-per-device-data#Create-the-payload-for-a-device-validation-request) since 17 July at 19:10hs GMT. The service information page says the service was running in green status but that isn't the case and we currenly have stop consuming it. Is it being looked at? Are you aware of this issue? Can you give us an estimate of when it should be working correctly?

email sent to to an iCloud account is landed to junk when email sent from user-*dev*.company.com micro service
Our company has a micro service which sends a notification email to an iCloud account/email and the email is going to the junk folder. As we tested, the email generated from user-field.company.com goes to the Inbox, while the email from user-dev.company.com goes to the Junk folder. Is there a way to avoid sending the emails to client's Junk folder when the email is sent from a specific company domain?

Control over "\(your_app) wants to open \(another_app)" Dialog
I can't find any information about why this is happening, nor can I reproduce the 'successful' state on this device. My team needs to understand this behavior, so any insight would be greatly appreciated! The expected behavior: If I delete both apps and reinstall them, attempting to open the second app from my app should trigger the system confirmation dialog. The specifics: I'm using the MSAL library. It navigates the user to the Microsoft Authenticator app and then returns to my app. However, even after resetting the phone and reinstalling both apps, the dialog never shows up (it just opens the app directly). Does anyone know the logic behind how iOS handles these prompts or why it might be persistent even after a reset? Thanks in advance!

ASWebAuthenticationSession: Form submit fails on TestFlight unless submitted through Keychain autofill
I'm experiencing a strange issue where ASWebAuthenticationSession works perfectly when running from Xcode (both Debug and Release), but fails on TestFlight builds. The setup: iOS app using ASWebAuthenticationSession for OIDC login (Keycloak) Custom URL scheme callback (myapp://) prefersEphemeralWebBrowserSession = false The issue: When using iOS Keychain autofill (with Face ID/Touch ID or normal iphone pw, that auto-submits the form) -> works perfectly When manually typing credentials and clicking the login button -> fails with white screen When it fails, the form POST from Keycloak back to my server (/signin-oidc) never reaches the server at all. The authentication session just shows a white screen. Reproduced on: Multiple devices (iPhone 15 Pro, etc.) iOS 18.x Xcode 16.x Multiple TestFlight testers confirmed same behavior What I've tried: Clearing Safari cookies/data prefersEphemeralWebBrowserSession = true and false Different SameSite cookie policies on server Verified custom URL scheme is registered and works (testing myapp://test in Safari opens the app) Why custom URL scheme instead of Universal Links: We couldn't get Universal Links to trigger from a js redirect (window.location.href) within ASWebAuthenticationSession. Only custom URL schemes seemed to be intercepted. If there's a way to make Universal Links work in this context, without a manual user-interaction we'd be happy to try. iOS Keychain autofill works The only working path is iOS Keychain autofill that requires iphone-authentication and auto-submits the form. Any manual form submission fails, but only on TestFlight - not Xcode builds. Has anyone encountered this or know a workaround?

I have enabled FileVault on macOS having a custom authorisation plugin , which will load our multi-factor authentication (MFA) window . This third-party custom authorisation plugin replaced loginwindow:login mechanism from authorisation db (system.login.console) .After these changes, during reboot, we observed that the focus isnt on our custom Xib window.We noticed that the custom Xib window is rendered on a completely black background . End user has to use mouse to click on the custom Xib window, so that the textbox gains its focus. The possible solutions we have tried, Simulating mouse click Making Window to gain focus using makeKeyAndOrderFront Steps to reproduce: Enable Filevault on the machine Remove loginwindow:login and add your custom authorisation plugin in its place with a textbox to capture password 3.Perform reboot of the machine 4.The custom xib window is rendered on a black window but the window doesnt gain focus. The user has to perform a mouse click on the window to gain its focus Any help would be greatly appreciated on the above mentioned issue

App Attest Issue in Production - Attestation Object Size Increased
Hi Apple Team and Community, We encountered a sudden and widespread failure related to the App Attest service on Friday, July 25, starting at around 9:22 AM UTC. After an extended investigation, our network engineers noted that the size of the attestation objects received from the attestKey call grew in size notably starting at that time. As a result, our firewall began blocking the requests from our app made to our servers with the Base64-encoded attestation objects in the payload, as these requests began triggering our firewall's max request length rule. Could Apple engineers please confirm whether there was any change rolled out by Apple at or around that time that would cause the attestation object size to increase? Can anyone else confirm seeing this? Any insights from Apple or others would be appreciated to ensure continued stability. Thanks!

Custom right using builtin:authenticate on macOS
When implementing a custom right in macOS authorizationdb, the mechanism array element builtin:authenticate is displaying the message 'Enter the name and password of a user in the "(null)" group to allow this.' on the macOS credential prompt UI popup. I am trying to find a fix to avoid the reference to null group in the message label that is displayed just above the username and password input fields. The current plist uses class as the key and value as the evaluate-mechanisms. The mechanisms array includes mechanism array with elements "builtin:login-begin", "mycustombundle:mycustompreaction", "builtin:authenticate", "mycustombundle:mycustommechanism". I have tried specifying group in the plist, have tried setting hint in the MechanismInvoke for group, username, security, authority, prompt, reason among several other hints into the context duing the execution of mycustombundle:mycustompreaction, but none seem to fix the "(null)" in the message label. Any help is greately appreciated. There is not much of any documentation for developers implementing custom authorization in macOS.

iPhone + Safari + Passwords violates WebAuthn spec when pubKeyCredParams doesn't contain ES256
WebAuthn Level 3 § 6.3.2 Step 2 states the authenticator must : Check if at least one of the specified combinations of PublicKeyCredentialType and cryptographic parameters in credTypesAndPubKeyAlgs is supported. If not, return an error code equivalent to "NotSupportedError" and terminate the operation. On my iPhone 15 Pro Max running iOS 18.5, Safari + Passwords does not exhibit this behavior; instead an error is not reported and an ES256 credential is created when an RP passes a non-empty sequence that does not contain {"type":"public-key","alg":-7} (e.g., [{"type":"public-key","alg":-8}]). When I use Chromium 138.0.7204.92 on my laptop running Arch Linux in conjunction with the Passwords app (connected via the "hybrid" protocol), a credential is not created and instead an error is reported per the spec.

Incorrect Branding and Messaging Displayed on "Call Customer Center" Feature
We’ve identified an issue in our app where, upon clicking the "Call Customer Center" button, users are unexpectedly shown a logo and message option on a native pop-up window. However, this wasn't the case before, and it should only display a phone number to dial, which was given inside our code. This is incorrect and misleading for our users, as: We are a Canadian-based service and have no affiliation with US messaging chat. The messaging feature was never enabled or intended for our app. Our app should only initiate a phone call to our customer support center — no messages or branding from third parties should appear
