Hi everyone, I have followed all the Apple procedures, read the forums, and looked at various experiences of other users who had my problem, but I haven’t found a solution. On my site, I have added login with all the “big” providers, and Apple is the only one missing. I’ve tried everything, but when the user logs in and is authenticated, I get an error. In order, here’s what I receive: Received Apple code: cfbf091dd6... JWT generated correctly HTTP Error (400): {"error":"invalid_client"} I’ve read all sorts of things, including that you have to wait up to 48 hours for the Key to be enabled. Any ideas? I’ve read that this is a common problem, but I haven’t found a valid solution. Thanks in advance to anyone who can help me.

I no longer have an app on the store. I do have an apple books account on the same login but there's no need for me to have the appstore connect account or whatever you call it and keep getting notifications when I don't have an app, don't want an app, will never do another app.

Recently I am trying to implement apple oauth in expo web version, I created the service id and other related info, i have issue @PostMapping("/callback") public ResponseEntity handleAppleCallback(@RequestParam Map<String, String> body) { String code = body.get("code"); String idToken = body.get("id_token"); if (code == null) { return ResponseEntity.badRequest().build(); } // Redirect to your Expo Web app with the code in query String frontendUrl = "https://mobile-dot-dev-epicportal.uc.r.appspot.com/apple-callback?code=" + code; return ResponseEntity.status(HttpStatus.FOUND) .header("Location", frontendUrl) .build(); } when i pass the code recived from apple to this route i am getting invalid_grant i am not sure what is wrong here

Hi, we are having Sign in with Apple issues. For a large % of new users on our app which select this option, the first name and last name values are not being passed to us. This is the case in both scenarios - where the user shares their email address or hides it, and happens on iPhone when the user selects the default iCloud account. We're unclear why this is occurring.

Hello everyone! We are from Russia, and we no longer have an official Apple store. All phones are imported through parallel imports. Yesterday, my wife logged out of her Apple ID and logged in to someone else's account, and as a result, her phone was in lost and locked mode. We have a sales receipt confirming the purchase, but it is from a Russian store. Can you please tell me if there is a way to unlock the phone or if it is already a brick? Scammers are asking for money to unlock the phone. Thank you in advance for your reply!

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://developer.apple.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 !

My existing iOS app has a legacy App ID prefix which does not match my Team ID. I am planning on migrating it to my Team ID. I am aware of the potential issues with keychain access groups, however I wanted to double check that there are no issues related to "Sign in with Apple". My app is currently the "Primary App ID" in the "Sign in with Apple" settings. The full App ID is listed there, including the prefix. Can someone from the relevant team at Apple confirm that changing the App ID prefix to Team ID has no effect related to "Sign in with Apple"?

Our app (app1) was recently transferred from Team A to Team B. While reviewing the Apple login implementation, we discovered that "Sign in with Apple" had been incorrectly set up to use the Service ID and App ID of another app (app2) — specifically, it was using app2.service as the Service ID and app2 as the App ID. In other words, app1’s users were authenticated through app2’s credentials due to a misconfiguration on our part. Now that app1 has been transferred to Team B, we’re trying to preserve those users. However, app2 is still in Team A, and we cannot maintain Team A anymore — meaning app2 must also be transferred to Team B if we want to retain access to the user data. One idea we considered is submitting app2 for App Review (even though it's non-functional) just to fulfill the transfer requirements, and then transferring it to Team B solely to retain the Apple login setup. Is this approach acceptable? Are there any recommended ways to handle this kind of misconfiguration while preserving existing Sign in with Apple users?

Our organization operates a web platform that hosts numerous newspaper properties. We recently acquired a new newspaper and are in the process of integrating it into our platform. As part of this transition, we’ve successfully transferred the App and App ID for the acquired newspaper into our Apple Developer portal. However, no Service ID associated with Sign in with Apple was included in the transfer. Our current implementation uses a single, unified Service ID for all existing newspaper properties. This Service ID facilitates OAuth via a centralized Identity Server. The organization we acquired provided a CSV file containing a list of transport_ids, and based on our understanding, we’re expected to use the Apple endpoint: https://appleid.apple.com/auth/usermigrationinfo to initiate a registration process by submitting our Service ID (client_id) along with each transport ID. This step is required before users can sign in, and it should return the existing relay email address. We have a few key concerns: Service ID Compatibility It appears that users cannot be transferred between Service IDs. In our case, there are now two: a.) Our existing Service ID (used across all current newspaper properties) b.) A separate Service ID previously associated with the acquired newspaper 3.) Due to architectural constraints, our platform cannot dynamically toggle between multiple Apple Service IDs. All properties authenticate through our unified Identity Server bound to our existing Service ID. 4.) Is it possible to call /usermigrationinfo using our existing Service ID rather than the one originally used by the acquired property? 5.) Relay Email and Apple ID Consistency 6.) We’re seeing conflicting information about whether the Apple relay email address (@privaterelay.appleid.com) and the Apple user ID are preserved during this migration. Some sources suggest that the relay email and Apple ID are tightly coupled to both the Service ID and Team ID. 7.) If we call /usermigrationinfo with our existing Service ID, will the same relay email be returned, or will Apple issue a new one?

Hello. Some of my users are signing in using "Sign in with Apple" and choosing the "Hide My Email" option. As expected, Apple generates a private relay email address. However, emails that we send to these addresses are not being delivered — the users report that they are not receiving anything. We’ve configured our email sending domains in the Apple Developer portal, and all domains have been successfully verified with SPF records marked as OK. Our system is sending the emails as usual, and we're not receiving any bounce-back or error messages. Everything looks fine on our end. Is there something specific we need to configure to ensure emails sent to privaterelay.appleid.com addresses are delivered correctly? Are there any known limitations or additional requirements for using Apple's private relay service? Thank you!

Dear Sir or Madam, Thank you for your continued support. My name is Sato from atmos. We are currently working with a vendor to implement Apple Sign In as a login method for our app, but we are encountering some issues and would like to contact you about them. The Apple Sign In functionality itself is almost complete, but during verification, email relay is not permitted by Apple when Apple Sign In is used with a non-public email address, making it impossible to complete email relay verification for users. We have reviewed the settings in “/account/resources/services/configure,” checked your FAQ, and explored all other possible solutions within our scope, but the situation remains unchanged. Would it be possible for your team to confirm the cause of the email relay not being permitted? Thank you for your assistance. atmos Sato Translated with DeepL.com (free version)

Private relay emails are not being delivered, even though we've followed the guidance here, https://developer.apple.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).

Hello, I’m experiencing an issue with email deliverability when sending messages through Apple’s private email relay service. Our app uses “Sign in with Apple” and sends communication emails to users through relay addresses . Messages are successfully delivered but are consistently being placed in users’ spam or junk folders. Configuration summary: Domain: myapp.example Mail server: OVH SMTP SPF and DKIM: Active and validated Domain and sender registered under “Sign in with Apple for Email Communication” Messages pass SPF and DKIM checks successfully, but emails relayed by Apple’s private service are still being marked as spam. Could anyone confirm if there are additional steps or configurations required to improve deliverability (e.g., DMARC alignment or specific header requirements)? Thank you for your help!

If a user triggers account revoke on their Apple ID—but does not perform an in-app account deletion—will Apple send a server-to-server notification to inform us of this revoke event? Additionally, in this scenario, if the user later wants to restore access to their existing game account data (for example, by re-binding Sign in with Apple or switching to another login method), are developers expected to restore all previously linked game data, or should the revoke event be treated as a permanent loss of authorization?

Goal I want to reply to feedback from customers who signed up using a private.relay account. Problem I am getting this error when sending an email: Reporting-MTA: dns; mailfout.stl.internal X-Postfix-Queue-ID: B87481D0015B X-Postfix-Sender: rfc822; hello@mydomain.com Arrival-Date: Fri, 7 Nov 2025 03:37:29 -0500 (EST) Final-Recipient: rfc822; xxxx@privaterelay.appleid.com Original-Recipient: rfc822;xxxx@privaterelay.appleid.com Action: failed Status: 5.1.1 Remote-MTA: dns; smtp3.privaterelay.appleid.com Diagnostic-Code: smtp; 550 5.1.1 <hello@mydomain.com>: unauthorized sender What have I done?

Question detail Dear Apple Developer Technical Support, We are currently following the official Apple documentation “TN3159: Migrating Sign in with Apple users for an app transfer” to carry out a Sign in with Apple user migration after successfully transferring several apps to a new developer account. Here is a summary of our situation: Under the original Apple developer account, we had five apps using Sign in with Apple, grouped under a shared primary app using App Grouping. Recently, we transferred three of these apps to our new Apple developer account via App Store Connect. After the transfer, these three apps are no longer associated with the original primary App ID. We reconfigured individual Services IDs for each app in the new account and enabled Sign in with Apple for each. More than 24 hours have passed since the app transfer was completed. Now we are attempting to follow the migration process to restore user access via the user.migration flow. Specifically, we are using the following script to request an Apple access token: url = "https://appleid.apple.com/auth/token" headers = {"Content-Type": "application/x-www-form-urlencoded"} data = { "grant_type": "client_credentials", "scope": "user.migration", "client_id": "com.game.friends.ios.xxxx", # New Primary ID in the new account "client_secret": "<JWT signed with new p8 key>" } response = requests.post(url, headers=headers, data=data) However, the API response consistently returns: { "error": "invalid_client" } We have verified that the following configurations are correct: The client_secret is generated using the p8 key from the new account, signed with ES256 and correct key_id, team_id, and client_id. The client_id corresponds to the Services ID created in the new account and properly associated with the migrated app. The scope is set to user.migration. The JWT payload contains correct iss, sub, and aud values as per Apple documentation. The app has been fully transferred and reconfigured more than 24 hours ago. Problem Summary & Request for Support: According to Apple’s official documentation: “After an app is transferred, Apple updates the Sign in with Apple configuration in the background. This can take up to 24 hours. During this time, attempts to authenticate users or validate tokens may fail.” However, we are still consistently receiving invalid_client errors after the 24-hour waiting period. We suspect one of the following issues: The transferred apps may still be partially associated with the original App Grouping or primary App ID. Some Sign in with Apple configuration in Apple’s backend may not have been fully updated after the transfer. Or the Services ID is not yet fully operational for the transferred apps in the new account. We kindly request your assistance to: Verify whether the transferred apps have been completely detached from the original App Grouping and primary App ID. Confirm whether the new Services IDs under the new account are fully functional and eligible for Sign in with Apple with user.migration scope. Help identify any remaining configuration or migration issues that may cause the invalid_client error. If necessary, assist in manually ungrouping or clearing any residual App Grouping relationships affecting the new environment. We have also generated and retained the original transfer_sub identifiers and are fully prepared to complete the sub mapping once the user.migration flow becomes functional. Thank you very much for your time and support!

Hi Apple Developer Community, We have carefully reviewed the documentation on App Transfer and User Migration, but we still have a few unresolved questions regarding Apple Sign-In token behavior and testing strategies. Would appreciate any guidance! Token Behavior for Pre-Transfer App Versions After the app transfer: If a user logs in via an existing pre-transfer version of the app (published under Team A before transfer), will the Apple Sign-In token’s sub (or private email) switch to new value tie to Team B, or unchanged? This is critical for our user migration plan. Preserving sub Across Transfers (Internal Team Transfer) Since our app-transfer is an internal transfer (no change in app ownership outside our organization), is there a way to retain the original sub value（or private email） for users after the transfer? We are concerned that Apple Sign-In errors during the app transfer process may negatively impact user experience. Testing the Transfer Process Safely We’d like to simulate the app transfer and user migration process in a sandbox/test environment before executing it in production. Is there a way to test app transfers without affecting live users? (e.g., a staging mode for transfers) Thank you for your expertise! Any insights would be invaluable.

Hello I am trying to release an application using EXPO ROUTER + EXPO RN WEB. I am trying to implement Apple Login using Firebase. I have already put necessary info in both App Store Connect and Firebas console. Now I am so confused what I have to do next. What are some resource I could use or tips you could possibly give me when making apple login available using firebase. Pleas all helps are welcomed and needed

I’m using Sign in with Apple in my iOS app. When a user chooses “Hide My Email”, I receive the @privaterelay.appleid.com relay address. For marketing reasons, I would prefer to have the user’s real email address instead of the relay email. I want to stay compliant with App Store Review and the Sign in with Apple design/UX requirements. My questions are: Is it allowed to force the user (as part of the registration process) to provide their real email address, even if they chose “Hide My Email” during Sign in with Apple? Are there any specific App Store Review guidelines that forbid: Blocking sign up or access to features if the user keeps the relay email, or Showing a strong prompt like “We can’t log you in unless you share your real email”? What is the recommended, compliant pattern for collecting a “real” email when using Sign in with Apple + Private Relay? I’d appreciate any official clarification or examples of what App Review considers acceptable vs. reject-worthy here.

Our background monitoring application uses a Unix executable that requests Screen Recording permission via CGRequestScreenCaptureAccess(). This worked correctly in macOS Tahoe 26.0.1, but broke in 26.1. Issue: After calling CGRequestScreenCaptureAccess() in macOS Tahoe 26.1: System dialog appears and opens System Settings Our executable does NOT appear in the Screen Recording list Manually adding via "+" button grants permission internally, but the executable still doesn't show in the UI Users cannot verify or revoke permissions Background: Unix executable runs as a background process (not from Terminal) Uses Accessibility APIs to retrieve window titles Same issue occurs with Full Disk Access permissions Environment: macOS Tahoe 26.1 (worked in 26.0.1) Background process (not launched from Terminal) Questions: Is this a bug or intentional design change in 26.1? What's the recommended approach for background executables to properly register with TCC? Are there specific requirements (Info.plist, etc.) needed? This significantly impacts user experience as they cannot manage permissions through the UI. Any guidance would be greatly appreciated. Thank you
