Hi, I'm trying to implement web-browser SignIn with Apple with my new app. I'm trying to "Associate your website to your app" like described in this doc: https://aninterestingwebsite.com/help/account/capabilities/configure-sign-in-with-apple-for-the-web So I created a Service ID for this specific login. I want this login page to display my app icon and name when presented to users. My issue: When I associate my new app the the service, the link is somehow not working. The login page show the "service" login (with a generic apple logo and the Service ID's name) instead of the actual App name. I'v been able to link my new service to older apps succesfully !!! (the login page correctly shows the old apps icons and names) Why is my new app not associated with the service ? I am missing something here ? is there an additionnal step that I need to take in order to link the service to my newest app ? Thanks !

Can someone please guide me on the entire process of integrating ads in an IOS application using google's admob sdk? Not related to code but things related to Apple's privacy policy. Which options do need to select or specify in my app profile's privacy policy (identifier) section?

Dear Apple Support Team, I hope this message finds you well. Our tech team is currently working on integrating the Apple Sign-In feature, and we have a specific query where we would appreciate your guidance. Background Context: We have several applications across different brands and are aiming to implement a unified sign-up and sign-in experience. Currently, we are utilizing a shared website to enable single sign-in functionality across all these applications. Our Query: If we embed the same website in all of these applications and implement the Apple Sign-In within this website—using a dedicated Service ID that is configured with the App Store name and icon—will users consistently see the Apple Sign-In pop-up with the Service ID’s name and icon, regardless of which base application (e.g., App A, App B, etc.) the website is accessed from? We would like to ensure a seamless and consistent user experience and want to confirm that the branding within the Apple Sign-In prompt will reflect the Service ID’s configuration, rather than that of the hosting app. Looking forward to your guidance on this matter.

I have an Autofill Passkey Provider working for Safari and Chrome via WebAuthn protocol. Unfortunately, Chrome will not offer my extension as a logon credential provider unless I add the credential to the ASCredentialIdentityStore. I wonder what is the best way to access the ASCredentialIdentityStore from an AutoFill extension? I understand I cannot access it directly from the extension context, so what is the best way to trigger my container app to run, based on a new WebAuthn registration? The best I can think of so far is for the www site to provide an App Link to launch my container app as part of the registration ceremony. Safari will offer my extension even without adding it to the ASCredentialIdentityStore, so I guess I should file a request with Chrome to work this way too, given difficulty of syncing ASCredentialIdentityStore with WebAuthn registration.

I'm testing app transferring, before, I have migrate user from teamA to teamB, including subA->transferSub->subB process, now I'm transfer the app from teamB to teamC, after the transfer requested, I can't get transfer_id by /usermigrationinfo api, which response 400 invalid request. the question is I can still get transfer sub by the auth/token api(grant_type: authorization_code) with teamB parameters(teamIdB/clientIdB/appSecretB/redirectUrlB/subB)，but the value is same as first time transfer_id which get during teamA to teamB. when use parameters above with target(teamIdC) to request /usermigrationinfo, invalid request was responsed. im sure that all parameters is correct, dose it cause by teamB still in 60-days first transferring(sure already accepted)?

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!

I received Apple’s recent notice about the new requirement to provide a server-to-server notification endpoint when registering or updating a Services ID that uses Sign in with Apple. (Official notice: https://aninterestingwebsite.com/news/?id=j9zukcr6 ) We already use Sign in with Apple on our website and app, but only as a login method for pre-registered users, not as a way to create new accounts. That means users already exist in our system, and Apple login is used only for authentication convenience (similar to linking a social account). I have some questions about how to properly implement the required server-to-server notifications in this case: 1. email-enabled / email-disabled: We don’t use or store the email address provided by Apple. Are we still required to handle these events, or can we safely ignore them if the email is not used in our system? 2. consent-revoked: We don’t store Apple access or refresh tokens, we use them only during login and discard them immediately. In this case, do we still need to handle token revocation, or can we simply unlink the Apple login from the user account when receiving this notification? 3. account-delete: If a user deletes their Apple account, we can unlink the Apple login and remove related Apple data, but we cannot delete the user’s primary account in our system (since the account exists independently). Is this acceptable under Apple’s requirements as well? We want to make sure our implementation aligns with Apple’s policy and privacy requirements, while maintaining consistency with our existing account management system. If anyone from Apple or other developers who implemented similar logic could provide guidance or share examples, it would be greatly appreciated. Thank you!

Problem Summary I'm experiencing a persistent invalid-credential error with Apple Sign-In on iOS despite having verified every aspect of the configuration over the past 6 months. The error occurs at the Firebase Authentication level after successfully receiving credentials from Apple. Error Message: Firebase auth error: invalid-credential - Invalid OAuth response from apple.com. Environment Platform: iOS (Flutter app) Firebase Auth: v5.7.0 Sign in with Apple: v6.1.2 Xcode: Latest version with capability enabled iOS Target: 13.0+ Bundle ID: com.harmonics.orakl What Actually Happens ✅ Apple Sign-In popup appears ✅ User can authenticate with Apple ID ✅ Apple returns credentials with identityToken ❌ Firebase rejects with invalid-credential error The error occurs at Firebase level, not Apple level. What I've Tried Created a brand new Apple Key (previous key was 6 months old) Tested with both App ID and Service ID in Firebase Completely reinstalled CocoaPods dependencies Verified nonce handling is correct (hashed to Apple, raw to Firebase) Activated Firebase Hosting and attempted to deploy .well-known file Checked Cloud Logging (no detailed error messages found) Disabled and re-enabled Apple Sign-In provider in Firebase Verified Return URL matches exactly Waited and retried multiple times over 6 months Questions Is the .well-known/apple-developer-domain-association.txt file required? If yes, how should it be generated? Firebase Hosting doesn't auto-generate it. Could there be a server-side caching/blacklist issue with my domain or Service ID after multiple failed attempts? Should the Apple Key be linked to the Service ID instead of the App ID? The key shows as linked to Z3NNDZVWMZ.com.harmonics.orakl (the App ID). Is there any way to get more detailed error logs from Firebase about why it's rejecting the Apple OAuth response? Could using a custom domain instead of .firebaseapp.com resolve the issue? Additional Context Google Sign-In works perfectly on the same app The configuration has been reviewed by multiple developers Error persists across different devices and iOS versions No errors in Xcode console except the Firebase rejection Any help would be greatly appreciated. I've exhausted all standard troubleshooting steps and documentation. Project Details: Bundle ID: com.harmonics.orakl Firebase Project: harmonics-app Team ID: Z3N....... code : // 1. Generate raw nonce final String rawNonce = _generateRandomNonce(); // 2. Hash with SHA-256 final String hashedNonce = _sha256Hash(rawNonce); // 3. Send HASHED nonce to Apple ✅ final appleCredential = await SignInWithApple.getAppleIDCredential( scopes: [AppleIDAuthorizationScopes.email, AppleIDAuthorizationScopes.fullName], nonce: hashedNonce, // Correct: hashed nonce to Apple ); // 4. Create Firebase credential with RAW nonce ✅ final oauthCredential = OAuthProvider("apple.com").credential( idToken: appleCredential.identityToken!, rawNonce: rawNonce, // Correct: raw nonce to Firebase ); // 5. Sign in with Firebase - ERROR OCCURS HERE ❌ await FirebaseAuth.instance.signInWithCredential(oauthCredential);

Hi, Before I begin my investigation, I want to explain our code-level support process for issues related to Sign in with Apple—as the issue you’re reporting may be the result of any of the following: An error in your app or web service request. A configuration issue in your Developer Account. An internal issue in the operation system or Apple ID servers. To ensure the issue is not caused by an error within your app or web service request, please review TN3107: Resolving Sign in with Apple response errors to learn more about common error causes and potential solutions when performing requests. If the technote does not help identify the cause of the error, I need more information about your app or web services to get started. To prevent sending sensitive JSON Web Tokens (JWTs) in plain text, you should create a report in Feedback Assistant to share the details requested below. Additionally, if I determine the error is caused by an internal issue in the operating system or Apple ID servers, the appropriate engineering teams have access to the same information and can communicate with you directly for more information, if needed. Please follow the instructions below to submit your feedback. Gathering required information for troubleshooting Sign in with Apple authorization and token requests For issues occurring with your native app, perform the following steps: Install the Accounts/AuthKit profile on your iOS, macOS, tvOS, watchOS, or visionOS device. Reproduce the issue and make a note of the timestamp when the issue occurred, while optionally capturing screenshots or video. Gather a sysdiagnose on the same iOS, macOS, tvOS, watchOS, or visionOS device. Create a report in Feedback Assistant, and ensure your feedback contains the following information: the primary App ID or Bundle ID the user’s Apple ID, email address, and/or identity token the sysdiagnose gathered after reproducing the issue the timestamp of when the issue was reproduced screenshots or videos of errors and unexpected behaviors (optional) For issues occurring with your web service, ensure your feedback contains the following information: the primary App ID and Services ID the user’s Apple ID, email address, and/or identity token the failing request, including all parameter values, and error responses (if applicable) the timestamp of when the issue was reproduced (optional) screenshots or videos of errors and unexpected behaviors (optional) Important: If providing a web service request, please ensure the client secret (JWT) has an extended expiration time (exp) of at least ten (10) business days, so I have enough time to diagnose the issue. Additionally, if your request requires access token or refresh tokens, please provide refresh tokens as they do not have a time-based expiration time; most access tokens have a maximum lifetime of one (1) hour, and will expire before I have a chance to look at the issue. Submitting your feedback Before you submit to Feedback Assistant, please confirm the requested information above (for your native app or web service) is included in your feedback. Failure to provide the requested information will only delay my investigation into the reported issue within your Sign in with Apple client. After your submission to Feedback Assistant is complete, please respond in your existing Developer Forums post with the Feedback ID. Once received, I can begin my investigation and determine if this issue is caused by an error within your client, a configuration issue within your developer account, or an underlying system bug.

"Our app has absolutely no integration with DiDi login. We only integrate WeChat, QQ, carrier, and Apple ID login, and all related login entry icons are local resources. On an iPhone 16 Pro Max device with iOS system version 18.7, there was one isolated incident where the Apple ID login entry icon mysteriously changed to the DiDi app icon. What could be the possible iOS system-level causes for this?"

Our proposed solution to identify an app user when opening a website operated by app developer is: Apps sends a request to backed with app users auth header Backend fetches a generated authenticated url from website backend, based on users auth header App opens it in browser The browser journey is self contained within domain of the business. Would this interaction require an ATT request given that the users identity cannot be tracked back to the app user ? Thanks

I understand from the recent Apple Developer News that Korean developers are now required to register a URL to receive notifications from the Apple server when creating or modifying a Sign in With Apple Service ID. However, it is not clear whether simply registering the URL is sufficient, or if it is also mandatory to implement the real-time processing of those notifications. I am inquiring whether the processing part is also a mandatory requirement.

With the new ios 26 update, certain numbers will be filtered into other inboxes within imessage. What numbers are classified as "known", and will not be moved into these filters. Do they need to be a contact in your phone, or if a business texts you how will that be filtered?

Hey folks, I'm seeing an issue where my iOS app is getting an "unknown" error when US users try to sign in with Apple. It works fine for users in other countries like the UK, Singapore, and Taiwan. Could it be related to my developer account not being based in the US? Or have I missed something in my settings? Thanks in advance!

We have a crash on DCDevice.current.isSupported We want to try to make a serial queue to generate tokens but the side effect would be the same token would be used on multiple server API requests that are made within a few ms of each other? Is this safe or will the Apple server immediately reject the same token being reused? Can you share how long tokens are safe to use for? Here is the code we want to try final actor DeviceTokenController: NSObject { static var shared: DeviceTokenController = .init() private var tokenGenerationTask: Task<Data?, Never>? var ephemeralDeviceToken: Data? { get async { // Re-using the token for short periods of time if let existingTask = tokenGenerationTask { return await existingTask.value } let task = Task<Data?, Never> { guard DCDevice.current.isSupported else { return nil } do { return try await DCDevice.current.generateToken() } catch { Log("Failed to generate ephemeral device token", error) return nil } } tokenGenerationTask = task let result = await task.value tokenGenerationTask = nil return result } } }

Hi, I followed step by step documentation to implement SignIn with Apple in iOS/Android application. I created an AppId com.nhp.queenergy, a related ServiceId com.nhp.queenergy.apple, and a KeyId. Authorization request is correctly performed by using ServiceId as client_id and my backend redirect_uri I receive code on my backend Token request is performed by using ServiceId as client_id, same redirect_uri, the code I have just received and the client_secret as JWT signed with my .p8 certificate with the following decoded structure Header { "kid": , "typ": "JWT", "alg": "ES256" } Payload { "iss": , "sub": "com.nhp.queenergy.apple", "aud": "https://appleid.apple.com", "exp": 1756113744, "iat": 1756111944 } I always receive "invalid_grant" error without any further error description. Moreover the error is always the same even though I use any fake string as client secret. If the code expires, as expected the error changes by adding "The code has expired or has been revoked." I really don't know how to solve this issue Best regards

Hi everyone, We just completed an App Store Connect app transfer between two developer teams and ran into what seems like an inconsistency with TN3159 (Migrating Sign in with Apple users for an app transfer). According to the technote, both the source and destination teams should be able to call /auth/usermigrationinfo for 60 days after the transfer, even if the migration wasn’t run beforehand. However, right after the transfer completed, the source team (Team A) started receiving: {"error":"invalid_client"} on all /auth/usermigrationinfo requests, even though /auth/token with scope=user.migration still works fine. What we verified before transfer: Team A’s Sign in with Apple key (ES256) was linked to the app and Services ID. OAuth flow for com.org.appname.web returned valid tokens, and the decoded ID token showed aud=com.org.appname.web with a valid private relay email, confirming the key was trusted. What happens after transfer: The key now shows “Enabled Services: —” and the App/Services IDs are no longer selectable in the Developer portal. /auth/usermigrationinfo immediately returns invalid_client for Team A, even within the same day of the transfer. This effectively makes Team A unable to generate transfer_sub values, blocking the migration flow TN3159 describes. Questions: Is Team A supposed to retain authorization to call /auth/usermigrationinfo for 60 days post-transfer? If yes, is there any known workaround to re-authorize the key or temporarily re-bind it to the transferred identifiers? If not, does this mean transfer_sub must be generated before transfer acceptance, contrary to how TN3159 reads? Would really appreciate any confirmation or guidance from Apple or anyone who’s gone through this recently. Thanks,

Hello everyone, I'm encountering a persistent 503 Server Temporarily Not Available error when trying to implement "Sign in with Apple" for my web application. I've already performed a full review of my configuration and I'm confident it's set up correctly, which makes this server-side error particularly confusing. Problem Description: Our web application uses Firebase Authentication to handle the "Sign in with Apple" flow. When a user clicks the sign-in button, they are correctly redirected to the appleid.apple.com authorization page. However, instead of seeing the login prompt, the page immediately displays a 503 Server Temporarily Not Available error. This is the redirect URL being generated (with the state parameter truncated for security): https://appleid.apple.com/auth/authorize?response_type=code&client_id=XXXXXX&redirect_uri=https%3A%2F%2FXXXXXX.firebaseapp.com%2F__%2Fauth%2Fhandler&state=AMbdmDk...&scope=email%20name&response_mode=form_post Troubleshooting Steps Performed: Initially, I was receiving an invalid_client error, which prompted me to meticulously verify every part of my setup. I have confirmed the following: App ID Configuration: The "Sign in with Apple" capability is enabled for our primary App ID. Services ID Configuration: We have a Services ID configured specifically for this. The "Sign in with Apple" feature is enabled on this Services ID. The domain is registered and verified under "Domains and Subdomains". Firebase Settings Match Apple Settings: The Services ID from Apple is used as the Client ID in our Firebase configuration. The Team ID is correct. We have generated a private key, and both the Key ID and the .p8 file have been correctly uploaded to Firebase. The key is not revoked in the Apple Developer portal. Since the redirect to Apple is happening with the correct client_id and redirect_uri, and the error is a 5xx server error (not a 4xx client error like invalid_client), I believe our configuration is correct and the issue might be on Apple's end. This has been happening consistently for some time. My Questions: What could be causing a persistent 503 Server Temporarily Not Available error on the /auth/authorize endpoint when all client-side configurations appear to be correct? What is the formal process for opening a technical support ticket (TSI) directly with Apple Developer Support for an issue like this? Thank you for any insights or help you can provide.

Confirmation on "Sign in with Apple JS" Web Implementation Compatibility Hello Developers We are trying to implement "Sign in with Apple JS" on our e-commerce website, which is built on a SaaS platform called Ticimax in Turkey. Our platform provider (Ticimax) claims that a web-based implementation of "Sign in with Apple" is not currently possible. They state this is due to "Apple's browser security policies" that prevent consistent and secure support across all major browsers, particularly Safari with its privacy features. Could you please confirm if there are any fundamental security policies or technical restrictions imposed by Apple that would prevent a standard, secure implementation of "Sign in with Apple JS" on a typical e-commerce website? We know many global websites use this feature successfully. We need to know if our provider's claim has a technical basis from Apple's perspective, or if this is a standard implementation challenge that developers are expected to handle (e.g., using pop-ups instead of redirects to comply with ITP). Any official clarification or documentation you can provide on this matter would be greatly appreciated. Thank you.
