We are experiencing an issue with Apple’s Private Email Relay service for Sign in with Apple users. Our setup details are as follows: • Domain: joinalyke.com • Domain successfully added under “Sign in with Apple for Email Communication” • SPF verified • DKIM enabled (2048-bit Easy DKIM via AWS SES) • Emails are being sent from S***@joinalyke.com Amazon SES confirms that emails sent to users’ @privaterelay.appleid.com addresses are successfully delivered (Delivery events recorded in SES and no bounce reported). However, users are not receiving the forwarded emails in their actual inboxes. Since: SES shows successful delivery, SPF and DKIM are properly configured, Domain is registered in the Apple Developer portal, we suspect that the Private Email Relay service may be blocking or not forwarding these emails. Could you please investigate whether: Our domain or IP reputation is being blocked or filtered, There are additional configuration requirements, The relay service is rejecting emails after acceptance, There are content-related filtering policies we should review. We are happy to provide message IDs, timestamps, and sample relay email addresses if required.

Hi team, We are experiencing an issue where some users in China are unable to create passkeys due to authentication errors. This is the UI flows The method we use to prompt users is passkey creation. Technically, this is implemented using Apple’s AuthenticationServices framework. We create an instance of ASAuthorizationController and conform to ASAuthorizationControllerDelegate to handle the results of the authentication attempt. In failure cases, we receive ASAuthorizationError.failed (code 1004), along with some additional details describing the nature of the failure. However, we are currently unable to determine the exact root cause of this issue or how to resolve it. At this point, we can only make assumptions based on the limited error information provided. Our current hypothesis is that due to network restrictions, Apple may be unable to reach the .well-known endpoint where we host the associated domain file. Alternatively, even if the file is successfully loaded and cached to Apple’s CDN, the system in China may not be able to reach the CDN itself. We would greatly appreciate it if you could help us understand what might be causing this problem and guide us on how we can resolve it effectively. Thanks, Hung

Since release of 18.4. prepareInterfaceToProvideCredential .oneTimeCode case is not called and instead prepareInterfaceForUserChoosingTextToInsert() is called. That is the wrong delegate for this case and it causes confusion for the users. Also, some TOTP fields are recognised however, the key icon button is not presented above the keyboard next to TOTP suggestions. I've also tested 18.5 and it has the same issue. provideOneTimeCodeWithoutUserInteraction works just fine.

Hi everyone, I am currently implementing Server-to-Server Notifications for Sign in with Apple. I’ve encountered a discrepancy between the official documentation and the actual payload I received, and I would like to clarify which one is correct. The Situation: I triggered an account deletion event via privacy.apple.com to test the notification flow. When my server received the notification, the type field in the JSON payload was account-deleted (past tense). The Issue: According to the official Apple documentation, the event type is listed as account-delete (present tense). Here is the discrepancy I am observing: Documentation: account-delete Actual Payload: account-deleted My Question: Is the documentation outdated, or is this a known inconsistency? Should I handle both strings (account-delete and account-deleted) in my backend logic to be safe, or is account-deleted the new standard? Any insights or confirmation from those who have implemented this would be greatly appreciated. Thanks!

Private relay emails are not being delivered, even though we've followed the guidance here, https://aninterestingwebsite.com/help/account/capabilities/configure-private-email-relay-service/ iCloud, gmail etc. get delivered fine but as soon as its a private relay email address they get bounced as unauthorized sender. We've tried a couple of domains but here I'll document test.x.domain.com We have registered domains (test.x.domain.com), also the sender communication emails just to be safe (noreply at test.x.domain.com).

Hi there, I'm trying to use SFAuthorizationPluginView in order to show some fields in the login screen, have the user click the arrow, then continue to show more fields as a second step of authentication. How can I accomplish this? Register multiple SecurityAgentPlugins each with their own mechanism and nib? Some how get MacOS to call my SFAuthorizationPluginView::view() and return a new view? Manually remove text boxes and put in new ones when button is pressed I don't believe 1 works, for the second mechanism ended up calling the first mechanism's view's view() Cheers, -Ken

Hi I am experiencing a persistent 'invalid_client' error when attempting to exchange the authorization code for an access token using Sign in with Apple for my website (https://www.vitamarinaweb.com). Current Setup & Steps Taken: Identifier: I am using the Service ID com.vitamarinaweb.web1, which is correctly linked to the Primary App ID com.vitamarinaweb.web. Client Secret: I have generated a fresh Client Secret (JWT) using a valid Key (.p8) and confirmed the Team ID (29J763Q88J) and Key ID (RRW6536D27) are correct. Redirect URIs: My Return URL is set to https://www.vitamarinaweb.com/login.php and I have verified there are no trailing spaces or mismatches. Manual Test (CURL): When I perform a manual POST request via CURL using the generated Client Secret, I receive an 'invalid_grant' response (meaning the Client Secret and Client ID are accepted, and only the temporary code is rejected as expected). The Issue: Despite the CURL success, every request initiated through the web browser/PHP application returns {"error":"invalid_client"}. Verification Requested: Could you please verify if there is a synchronization delay or a specific block on Service ID com.vitamarinaweb.web1? Is there any internal mismatch between the Key ID RRW6536D27 and its association with the newly created Service ID? I have already cleared browser caches and tried multiple devices (different IP addresses) with the same result. Thank you for your assistance."

Hi everyone, I'm currently working on a native macOS app (built with SwiftUI) and I'm trying to implement Password AutoFill functionality so users can use their saved credentials from Keychain or third-party password managers. I've gone through Apple's documentation, WWDC sessions, and sample code, but I've noticed that the resources primarily focus on iOS and web implementations. There's very limited guidance specifically for macOS. I've set up: Associated Domains entitlement with the webcredentials: service The apple-app-site-association file on my server TextField with .textContentType(.username) and SecureField with .textContentType(.password) However, I'm still not seeing the expected AutoFill behavior on macOS like I would on iOS. Has anyone successfully implemented Password AutoFill on a native macOS app? Are there any macOS-specific considerations or additional steps required that differ from iOS? Any guidance, sample code, or pointers to documentation I might have missed would be greatly appreciated.

Hello, I have encountered several challenges related to System Integrity Protection (SIP) state detection and code signing requirements. I would like to seek clarification and guidance on the proper approach to programmatically determine the SIP state. Here are the issues I’ve encountered: XPC Code Signing Check APIs: APIs like setCodeSigningRequirement and setConnectionCodeSigningRequirement do not work when SIP disabled and that's ok given what SIP is. LaunchCodeRequirement API: When using Process.launchRequirement, the LaunchCodeRequirement API does not function anymore when SIP disabled. The IsSIPProtected requirement behaves in a way that is not clearly documented -- it appears to only apply to pre-installed Apple apps. Legacy APIs: Older APIs like SecCodeCheckValidity are likely to be non-functional, though I haven’t had the chance to validate this yet. Private API Concerns: So to mitigate those limitations I prefer my app to not even try to connect to untrusted XPC or launch untrusted Processes when SIP is disabled. The only way to determine SIP state I could find is a low-level C function csr_get_active_config. However, this function is not declared in any publicly available header file, indicating that it is a private API. Since private APIs cannot be used in App Store-distributed apps and are best avoided for Developer ID-signed apps, this does not seem like a viable solution. Given these limitations, what is the recommended and proper approach to programmatically determine the SIP state in a macOS application? Any insights or guidance would be greatly appreciated. Thank you!

Using the simplified sign-in with tvOS and a third party password manager, I receive a complete ASPasswordCredential, and I can easily log into my app. When I do the same thing but with Apple's password manager as the source, I receive an ASPasswordCredential that includes the email address, but the password is an empty string. I have tried deleting the credentials from Apple Passwords and regenerating them with a new login to the app's website. I have tried restarting my iPhone. Is this the expected behavior? How should I be getting a password from Apple's Password app with an ASAuthorizationPasswordRequest?

Hi, We're in the process of implementing Apple's App Integrity, but am getting stalled due to missing documents. Can anyone assist with this? We've been following https://aninterestingwebsite.com/documentation/devicecheck/validating-apps-that-connect-to-your-server to make the necessary updates, but have come up short with where the document references decoding the Attestation Object. Can we get more information here and how the decoding process work?

Hi all, I’m building a macOS-native C++ trading bot, compiled via Xcode. It sends REST API requests to a crypto exchange (Bitvavo) that require HMAC-SHA256 signatures using a pre-sign string (timestamp + method + path + body) and an API secret. Here’s the issue: • The exact same pre-sign string and API secret produce valid responses when signed using Python (hmac.new(secret, msg, hashlib.sha256)), • But when I generate the HMAC signature using C++ (HMAC(EVP_sha256, ...) via OpenSSL), the exchange returns an invalid signature error. Environment: • Xcode 15.3 / macOS 14.x • OpenSSL installed via Homebrew • HMAC test vectors match Python’s output for basic strings (so HMAC lib seems correct) Yet when using the real API keys and dynamic timestamped messages, something differs enough to break verification — possibly due to UTF-8 encoding, memory alignment, or newline handling differences in the Xcode C++ runtime? Has anyone experienced subtle differences between Python and C++ HMAC-SHA256 behavior when compiled in Xcode? I’ve published a GitHub repo for reproducibility: 🔗 https://github.com/vanBaardewijk/bitvavo-cpp-signature-test Thanks in advance for any suggestions or insights. Sascha

Hello, I’m trying to set up Sign In with Apple for my Firebase Authentication integration. Steps I followed: Created a Service ID in Apple Developer, e.g. com.example.myapp.signin. Tried to enable Sign In with Apple and configure the Web Authentication Configuration. Web Domain: myapp.firebaseapp.com Return URL: https://myapp.firebaseapp.com/__/auth/handler When I click Save, I get the following error in the browser console and a blank response page: Unsupported Request PATCH to http://aninterestingwebsite.com/services-account/v1/bundleIds/XXXXXXXX not supported. Reference #... What I have verified so far: My Apple Developer Program membership is active (paid). My App ID (e.g. com.example.myapp) exists in Identifiers. The App ID has Sign In with Apple capability checked. I need to link the Service ID with this App ID for Firebase web-based auth. Goal: Complete setup of Apple as a sign-in provider in Firebase Authentication. To do this, Apple requires me to add the Firebase return URL above, but the Developer Portal prevents saving with the 501 error. Has anyone else run into this, and is there a workaround (e.g. enabling via Xcode, App Store Connect, or other methods)? Is this a known bug with the Apple Developer Portal? Here is the screenshot of the error: And Response part: Thanks in advance!

Hello, We’ve resumed the migration process after a break. Since my colleague is no longer with us, I had to go through the steps again myself. As before, we’re trying to migrate "Sign In with Apple" users from tenant TENANT_A with client_id=CLIENT_ID_A to tenant TENANT_B with client_id=CLIENT_ID_B I followed the procedure described here: [Apple Developer Documentation](https://aninterestingwebsite.com/documentation/technotes/tn3159-migrating-sign-in-with-apple-users-for-an-app-transfer – Migrating Sign In with Apple Users, essentially repeating what my coworker previously attempted in coordination with your employee Stephanie. Here’s a summary of the steps and the issue we’re facing: STEP 1 - get authcode for TEAM A curl --location 'https://appleid.apple.com/auth/token' --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode 'grant_type=client_credentials' --data-urlencode 'scope=user.migration' --data-urlencode 'client_id=pl.CLIEND_ID_A' --data-urlencode 'client_secret=<TEAM_A_SECRET>' I receive response: { "access_token": "<ACCESS_TOKEN_TEAM_A>", "token_type": "Bearer", "expires_in": 3600 } STEP 2 - get authcode for TEAB B curl --location 'https://appleid.apple.com/auth/token' --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode 'grant_type=client_credentials' --data-urlencode 'scope=user.migration' --data-urlencode 'client_id=CLIENT_ID_B' --data-urlencode 'client_secret=<TEAB_B_SECRET>' I receive response: { "access_token":"<ACCESS_TOKEN_TEAB_B>", "token_type": "Bearer", "expires_in": 3600 } STEP 3 - get transfer_sub from TEAM A curl --location 'https://appleid.apple.com/auth/usermigrationinfo' --header 'Authorization: Bearer <ACCESS_TOKEN_TEAM_A>' --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode 'client_id=CLIENT_ID_A' --data-urlencode 'client_secret=<TEAM_A_SECRET>' --data-urlencode 'sub=USER_SUB_FROM_TEAM_A' --data-urlencode 'target=TENANT_B' I receive response: { "transfer_sub": "USER_SUB_FROM_TEAM_B" } STEP 4 - Team B exchanges transfer identifers curl --location 'https://appleid.apple.com/auth/usermigrationinfo' --header 'Authorization: Bearer <ACCESS_TOKEN_TEAM_B' --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode 'client_id=CLIENT_ID_B' --data-urlencode 'client_secret=<TEAM_B_SECRET>' I receive response: { "error": "invalid_request" } We’ve created a new client_id under tenant B and want to migrate users there. However, we skipped the step described in Step 3 of the documentation(https://aninterestingwebsite.com/documentation/technotes/tn3159-migrating-sign-in-with-apple-users-for-an-app-transfer#3-Team-A-initiates-app-transfer-to-Team-B), which involves initiating an app transfer. The reason is that this client_id is used solely for web authentication, not for a mobile app, so we don’t have an app to transfer. Based on our analysis and your documentation, it seems this flow only works if the client_id matches across both tenants, which can only be achieved through an app transfer, something we cannot proceed with. Apple previously insisted that we migrate these users, but as shown above, we’re stuck. Is there any alternative flow available, or can you assist us in completing this migration?

Our app uses Sign in with Apple. In recent weeks (or months), we've noticed that emails sent to @privaterelay.appleid.com addresses are not being delivered. We're not receiving any bouncebacks or error messages from the mail server, but the emails never reach the user's mailbox. We've also checked spam folders, with no luck. We have verified that our Email Sources are configured correctly in Apple Developer settings. Is there any way to debug or trace what might be happening with these messages? Thanks in advance!

For context, my company develops a data loss prevention (DLP) product. Part of our functionality is the ability to detect sensitive data being pasted into a web browser or cloud-based app. The AppKit release notes for April 2025 document an upcoming “macOS pasteboard privacy” feature, which will presumably ship in macOS 26. Using the user default setting “EnablePasteboardPrivacyDeveloperPreview” documented in the release notes, I tested our agent under macOS 15.5, and encountered a modal alert reading " is trying to access the pasteboard" almost immediately, when the program reads the General pasteboard to scan its contents. Since our product is aimed at enterprise customers (and not individual Mac users), I believed Apple would implement a privacy control setting for this new feature. This would allow our customers to push a configuration profile via MDM, with the “Paste from Other Apps” setting for our application preset to “Allow”, so that they can install our product on their endpoints without manual intervention. Unfortunately, as of macOS 26 beta 4 (25A5316i), there does not seem to be any such setting documented under Device Management — for example in PrivacyPreferencesPolicyControl.Services, which lists a number of similar settings. Without such a setting available, a valuable function of our product will be effectively crippled when macOS 26 is released. Is there such a setting (that I've overlooked)? If not, allow me to urge Apple to find the resources to implement one, so that our customers can preset “Paste from Other Apps” to “Allow” for our application.

I have been implementing an sdk for authenticating a user. I have noticed that on iOS 18.5, whether using SFSafariViewController, or the sdk (built on ASWebAuthenticationSession), password autofill does not work. I have confirmed it works on a different device running iOS 18.0.1. Are there any work arounds for this at this time? Specifically for ASWebAuthenticationSession?

Apple Sign In - "Sign up not completed" Error in Development Build (React Native / Expo) Problem Summary I'm implementing Apple Sign In in a React Native app using expo-apple-authentication. The Apple sign-in dialog appears as expected, but after tapping "Continue," it displays the message: "Sign up not completed". No credential is returned, and the promise eventually rejects with ERR_REQUEST_CANCELED. App Configuration Platform: React Native (Expo SDK 52) Library: expo-apple-authentication v7.1.3 Target: iOS development build (not Expo Go) Bundle ID: com.example.appname.nativetest (new App ID created for testing) Apple Developer Console Setup (Reviewed Carefully) App ID Explicit App ID (not a wildcard) "Sign In with Apple" capability enabled No associated Services IDs or Sign In with Apple Keys Provisioning Profile Development profile created for the test App ID Profile includes the test device and development certificate Installed successfully and used to sign the app Certificates and Signing Valid Apple Developer Program membership Development certificate installed and selected during build App installs and launches properly on the test device Implementation Attempts Attempt 1: Supabase OAuth Method Initially tried using Supabase’s built-in Apple OAuth provider: Configured with team ID, key ID, and JWT credentials Proper redirect URLs and scheme were in place Resulted in OAuth URL pointing to Supabase instead of Apple, with incomplete client ID Ultimately moved to native implementation for improved control and reliability Attempt 2: Native Apple Sign In (Current Approach) Using expo-apple-authentication with the following code: const credential = await AppleAuthentication.signInAsync({ requestedScopes: [ AppleAuthentication.AppleAuthenticationScope.FULL_NAME, AppleAuthentication.AppleAuthenticationScope.EMAIL, ], }); Relevant app.config.js Section: ios: { bundleIdentifier: 'com.example.appname.nativetest', usesAppleSignIn: true, infoPlist: { NSAppTransportSecurity: { NSAllowsArbitraryLoads: true, NSAllowsLocalNetworking: true, }, }, }, plugins: ['expo-apple-authentication'] Observed Behavior AppleAuthentication.isAvailableAsync() → true Credential state → NOT_FOUND (expected for new user) Apple Sign In dialog appears and allows interaction User taps "Continue" → dialog reports "Sign up not completed" Eventually returns: [Error: The user canceled the authorization attempt], code ERR_REQUEST_CANCELED Confirmed Working Aspects AppleAuthentication API is available and initialized App is signed correctly and launches on the physical test device Apple Sign In dialog appears with correct styling and options Same result observed across both Wi-Fi and cellular networks Clean Setup and Debugging Performed Removed all previous build artifacts Created a new App ID and new provisioning profile Rebuilt the app using expo run:ios --device Validated entitlements and provisioning assignments Removed any Services IDs and Apple Sign In keys used in previous attempts Verified ATS (App Transport Security) policies allow dev-time communication Environment Information Device: iPhone (not simulator) iOS Version: 18.5 Xcode: Latest version Apple ID: Developer account with 2FA enabled Build Method: EAS CLI using expo run:ios --device Open Questions Has anyone experienced the "Sign up not completed" issue with a clean native implementation in Expo? Are there known limitations when testing Apple Sign In in local development builds? Could prior Apple ID authorization attempts impact sign-in behavior during testing? Are there any additional configuration steps, Info.plist changes, or entitlements required beyond those listed above? Thank you in advance for any suggestions or guidance. We’re hoping this is simply a configuration detail that needs to be adjusted.

In one of my apps I would like to find out if users have their device set up to authenticate with their Apple Watch. According to the documentation (https://aninterestingwebsite.com/documentation/localauthentication/lapolicy/deviceownerauthenticationwithcompanion) this would be done by evaluating the LAPolicy like this: var error: NSError? var canEvaluateCompanion = false if #available(iOS 18.0, *) { canEvaluateCompanion = context.canEvaluatePolicy(.deviceOwnerAuthenticationWithCompanion, error: &error) } But when I run this on my iPhone 16 Pro (iOS 18.5) with a paired Apple Watch SE 2nd Gen (watchOS 11.5) it always returns false and the error is -1000 "No companion device available". But authentication with my watch is definitely enabled, because I regularly unlock my phone with the watch. Other evaluations of using biometrics just works as expected. Anything that I am missing?

Is there any particular reason why ASWebAuthenticationSession doesn't have support for async/await? (example below) do { let callbackURL = try await webAuthSession.start() } catch { // handle error } I'm curious if this style of integration doesn't exist for architectural reasons? Or is the legacy completion handler style preserved in order to prevent existing integrations from breaking?
