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

Hello, I am currently process of migrating an app from Team A to Team B and attempting to generate transfer identifiers using the migration endpoint: POST https://appleid.apple.com/auth/usermigrationinfo. Content-Type: application/x-www-form-urlencoded However, I am consistently receiving an { "error": "access_denied" } response. [Current Configuration] Team A (Source): Primary App ID: com.example.primary Grouped App IDs: com.example.service (Services ID for Web) com.example.app (App ID for iOS - The one being transferred) All identifiers are under the same App Group. Team B (Destination): New App ID and Key created. [Steps Taken] Created a Client Secret (JWT) using Team A's Key ID and Team ID. The sub (subject) in the JWT is set to the Primary App ID of Team A. Requesting with client_id (Primary App ID), client_secret (JWT), and user_token. [Questions] 1. App Group Impact: Does the fact that the App being transferred is a Grouped App ID (not the Primary) affect the usermigrationinfo request? Should I use the Primary App ID or the specific Grouped App ID as the client_id? 2. Ungrouping Safety: If I need to ungroup the App ID from the Primary App ID to resolve this: Will existing users still be able to sign in without issues? Is there any risk of changing the sub (user identifier) that the app receives from Apple? Will this cause any immediate service interruption for the live app? Any insights on why access_denied occurs in this Primary-Grouped configuration would be greatly appreciated.

I have a question regarding Platform SSO and the use of Secure Enclave–backed keys with biometric policies. If we configure userSecureEnclaveKeyBiometricPolicy with userSecureEnclaveKey, my understanding is that the Secure Enclave key is protected by biometric authentication (e.g., Face ID / Touch ID). In this setup, during a login request that also refreshes the id_token and refresh_token, the assertion is signed using the userSecureEnclaveKey. My question is: Will this signing operation trigger a biometric prompt every time the assertion is generated (i.e., during login/token refresh) ?

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?

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?

My app Mocawave is a music player distributed through the Mac App Store. It declares specific audio document types (public.mp3, com.microsoft.waveform-audio, public.mpeg-4-audio, public.aac-audio) in its CFBundleDocumentTypes with a Viewer role. When a user sets Mocawave as the default app for audio files and double-clicks an MP3 downloaded from the internet (which has the com.apple.quarantine extended attribute), macOS displays the alert: "Apple could not verify [filename] is free of malware that may harm your Mac or compromise your privacy." This does not happen when: Opening the same file via NSOpenPanel from within the app Opening the same file with Apple's Music.app or QuickTime Player The app is: Distributed through the Mac App Store Sandboxed (com.apple.security.app-sandbox) Uses com.apple.security.files.user-selected.read-write entitlement The file being opened is a regular audio file (MP3), not an executable. Since the app is sandboxed and distributed through the App Store, I expected it to have sufficient trust to open quarantined data files without triggering Gatekeeper warnings — similar to how Music.app and QuickTime handle them. Questions: Is there a specific entitlement or Info.plist configuration that allows a sandboxed Mac App Store app to open quarantined audio files without this alert? Is this expected behavior for third-party App Store apps, or could this indicate a misconfiguration on my end? Environment: macOS 15 (Sequoia), app built with Swift/SwiftUI, targeting macOS 13+.

Hi, we are experiencing a specific issue with the Private Email Relay service. Our domain e.glassesdirect.co.uk consistently fails SPF verification while our other domains pass. The Pattern: We've noticed that domains with SPF records fitting in 1-2 TXT strings pass, but this specific domain (~750 chars, 3 TXT strings) fails. Technical Details: Team ID: SM2J7LWD33 Domain: e.glassesdirect.co.uk SPF Record length: ~750 characters Third-party tools (MxToolbox) confirm the record is valid. We suspect Apple's verification parser might be failing to handle concatenated TXT strings or hitting a size limit. Could any Apple engineers confirm if there is a character limit or a bug in handling multi-part TXT records?

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.

Apple has repeatedly ignored my reports about a critical privacy issue in Spotlight on macOS 26, and the problem persists in version 26.3 RC. This is not a minor glitch, it is a fundamental breach of user trust and privacy. Several aspects of Spotlight fail to respect user settings: • Hidden apps still exposed: In the Apps section (Cmd+1), Spotlight continues to display apps marked with the hidden flag, even though they should remain invisible. • Clipboard reactivation: The clipboard feature repeatedly turns itself back on after logout or restart, despite being explicitly disabled by the user. • Excluded files revealed: Most concerning, Spotlight exposes files in Suggestions and Recents (Cmd+3) even when those files are explicitly excluded under System Settings > Spotlight > Search Privacy. This behavior directly violates user expectations and system settings. It is not only a major privacy issue but also a security risk, since sensitive files can be surfaced without consent. Apple must address this immediately. Users rely on Spotlight to respect their privacy configurations, and the current behavior undermines both trust and security.

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

My application is supporting hybrid transport on FIDO2 webAuthn specs to create credential and assertion. And it support legacy passkeys which only mean to save to 1 device and not eligible to backup. However In my case, if i set the Backup Eligibility and Backup State flag to false, it fails on the completion of the registrationRequest to save the passkey credential within credential extension, the status is false instead of true. self.extension.completeRegistrationRequest(using: passkeyRegistrationCredential) The attestation and assertion flow only works when both flags set to true. Can advice why its must have to set both to true in this case?

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'm building a macOS app that registers itself for HTTP(S) url handling and would like it to participate in the ASWebAuthenticationSession fow. I did: update the plist to register as a handler for URL shemes (http, https, file) use NSWorkspace setDefaultApplication API to set this app as a default handler for urls in question wrote custom ASWebAuthenticationSessionWebBrowserSessionHandling implementation and set it as SessionManager's sessionHandler I launched this app from Xcode, then I triggered authentication flow from a third-party app. When the sign in flow is initiated, I can see that my app is activeated (willBecomeActive and didBecomeActive callbacks are both called), but there is no call for sessionHandler's begin() method. With some additional debugging I see that my app receives an apple event when the flow is started: {sfri,auth target=SafariLaunchAgent {qntp=90/$627......},aapd=TRUE If I switch system default browser back to Safari and then start the login flow, it correctly displays a sign in web page. What do I miss? PS. I'm on Tahoe 26.2

Hello, I am implementing "Sign in with Apple" on my backend and validating the Identity Token (JWT) received from the client. I noticed that for some users who choose the "Hide My Email" option, the is_private_email claim is missing from the ID Token payload, even though the email address clearly belongs to the private relay domain (@privaterelay.appleid.com). Here is an example of the decoded payload I received: { "iss": "https://appleid.apple.com", "aud": "com.platform.elderberry.new.signinwithapple", "exp": 1764402438, "iat": 1764316038, "sub": "000851.86193ef81ad247feb673746c19424f28.0747", "c_hash": "3FAJNf4TILzUgo_YFe4E0Q", "email": "x8sqp2dgvv@privaterelay.appleid.com", "email_verified": true, "auth_time": 1764316038, "nonce_supported": true // "is_private_email": true <-- This field is missing } My Questions: Is the is_private_email claim considered optional in the ID Token? Is it safe and recommended to rely solely on the email domain suffix (@privaterelay.appleid.com) to identify if a user is using a private email? Any insights or official references would be appreciated. Thanks.

I was experiencing a weird sign in error when using apple sign in with my app and wanted to put it here for anyone else who might experience it in the future, and so apple can make this requirement more clear. I was using CloudKit and apple sign in. If you are not using both this probably does not apply to you. Every time I would go to sign in in the iOS simulator I would enter my password, hit "sign in", and everything just froze. The very odd reason for this is if you are using iCloudKit and apple sign in you need to go to specifically the "identifiers" in the "Certificates, Identifiers & Profiles" menu (https://developer.apple.com/account/resources/identifiers/list). And from there you specifically need an App ID Configuration with apple sign in enabled. From there you have to have the same exact bundle identifier in Xcode under project settings(not an upper tab just click your project in the left panel). And that should allow you to both pass validation and have your sign in work. Hope this helps!

Hello, I have a question regarding the lifecycle of user consent and tokens in "Sign in with Apple." Specifically, I would like to understand the behavior of the auth/revoke API in relation to App Store Connect status changes. Impact of App Status Changes If an app is "Removed from Sale" or "Deleted" from App Store Connect, does Apple automatically revoke all associated user tokens and consent? Or is it still the developer's responsibility to programmatically revoke each user's token via the REST API to ensure the app is removed from the user’s "Apps Using Apple ID" list? API Availability after Removal Once an app is no longer available on the App Store (or its record is deleted in App Store Connect), is the auth/revoke REST API still accessible? I want to ensure that a developer can still perform necessary privacy clean-up tasks (revoking consent) even if the app is not currently distributed. Specific User Impacts of Non-Revocation If we do not call the revocation API, besides the app remaining in the "Sign in with Apple" list, what are the specific consequences for the user? Thank you for your guidance.

Hello, Is there any way to detect if the iOS screen is currently being shared via FaceTime or iPhone Mirroring? Our application relies on this information to help ensure that users are not accessing it from one location while physically being in another.
