Hello, I am currently implementing a biometric authentication registration flow using WebAuthn. I am using ASAuthorizationPlatformPublicKeyCredentialRegistrationRequest, and I would like to know if there is a way to hide the "Save to another device" option that appears during the registration process. Specifically, I want to guide users to save the passkey only locally on their device, without prompting them to save it to iCloud Keychain or another device. If there is a way to hide this option or if there is a recommended approach to achieve this, I would greatly appreciate your guidance. Also, if this is not possible due to iOS version or API limitations, I would be grateful if you could share any best practices for limiting user options in this scenario. If anyone has experienced a similar issue, your advice would be very helpful. Thank you in advance.

Hello everyone! I'm encountering an issue while trying to use the Sign in with Apple token revocation API. I've followed the steps outlined in the official documentation (https://developer.apple.com/documentation/sign_in_with_apple/revoke_tokens), but when I consume the API, I receive a 200 status code instead of the expected code. I've double-checked my implementation and can't find any obvious errors. Has anyone else experienced this issue before? I would greatly appreciate any suggestions or advice on how to resolve this issue. Thank you in advance for your help!

My existing chrome extension has "Sign in with Apple" given that we have iOS users. When user clicks "Continue with Apple" button in the extension log in pop up, this is what we do: javascript window.open( 'https://appleid.apple.com/auth/authorize?client_id=' + clientID + '&redirect_uri=' + backEndURL + '&response_type=id_token%20code&response_mode=form_post&scope=email%20name', 'Sign in with Apple', 'height=500,width=400,left=600,top=200,status=no,location=no,toolbar=no,menubar=no' ) In chrome, this opens a popup window with that URL. In Safari Converted Web Extension, it opens custom Apple sign in flow, where it says: "Do you want to sign in to *** with your Apple ID YYY?" and then with my mac password I'm able to authenticate. Afterwards, nothing happens. Expected: a redirect to the URL specified in the window.open. Now let's do a trick: I'll wrap the above window.open code into javascript setTimeout (() = {window.open (...)}, 3000) Because of security reasons, safari then won't open the popup after 3s and will display a notification in the toolbar "Popup blocked..". If we allow the popup, then it finally opens as a normal window popup and after sign in, it redirects to our backend and it successfully authenticates. Any ides what how to solve this? P.S. We're not able to use embedded Sign in with Apple JS - https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/configuring_your_webpage_for_sign_in_with_apple script because we can't host a remote code in the extension (it will be deprecated soon). So, we arere using this. - https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_js/incorporating_sign_in_with_apple_into_other_platforms

Hi everyone, I'm working on a hybrid web application that will serve as a unified login page for two of my existing apps. Both apps currently utilize Apple Sign In with separate app IDs. To provide a seamless user experience, I plan to create a unified login page that displays two distinct Apple Sign In buttons: "Log in with A Service" and "Log in with B Service". Each button will link to the respective Apple Sign In flow for that specific service and app ID. I'm seeking guidance on the following: Apple's Guidelines: Are there any specific Apple guidelines or restrictions that prohibit or discourage the display of multiple Apple Sign In buttons on a single page within a hybrid web app context? I appreciate any insights or suggestions you can provide. Thank you

I'm trying to set up Apple OAuth on my website. Whenever I go to Certificates, Identifiers & Profiles, It gives me the error 'Unable to find team with the given Team ID'

I am researching to apply Apple Sign In to my app. I see response data from Apple just include user name and email (phone number is not required also), but currently my app has only one login method that is by phone number. So I would like to ask:
 Can I request an phone number (by an customize popup) from the user after Signin Apple successfully? If not then which approach that can I apply? Many thanks!

Is there a way to know the event of user unlocking on iOS Device in Application?

Hi everyone, I'm working on a macOS authorization plugin (NameAndPassword) to enable users to log into their system using only MFA, effectively making it passwordless. To achieve this, I'm attempting to store the user's password securely in the Keychain so it can be used when necessary without user input. However, when I attempt to store the password, I encounter error code -25308. Below is the code I'm using to save the password to the Keychain: objc code (void)storePasswordInKeychain:(NSString *)password forAccount:(NSString *)accountName { NSData *passwordData = [password dataUsingEncoding:NSUTF8StringEncoding]; NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: @"com.miniOrange.nameandpassword", (__bridge id)kSecAttrAccount: accountName, (__bridge id)kSecValueData: passwordData, (__bridge id)kSecAttrAccessible: (__bridge id)kSecAttrAccessibleAfterFirstUnlock }; // Delete any existing password for the account OSStatus deleteStatus = SecItemDelete((__bridge CFDictionaryRef)query); if (deleteStatus == errSecSuccess || deleteStatus == errSecItemNotFound) { [Logger debug:@"Old password entry deleted or not found."]; } else { [Logger error:@"Failed to delete existing password: %d", (int)deleteStatus]; } // Add the new password OSStatus addStatus = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (addStatus == errSecSuccess) { [Logger debug:@"Password successfully saved to the Keychain."]; } else { [Logger error:@"Failed to save password: %d", (int)addStatus]; } } Any insights or suggestions would be greatly appreciated!

Hello, I have a public key of type Curve25519.KeyAgreement.PublicKey that I create from the raw representation using: Curve25519.KeyAgreement.PublicKey(rawRepresentation: Data(base64Encoded: "08sYq4gExgX+UApEwLaASkE+TZjAxG1FPYaT+mj2irk=")!) I'm trying to convert that key to a curve, but I don't see an equivalent function in CryptoKit for the Javascript function pk_to_curve25519. Can someone please help? For completeness, I'm trying to implement the handshake protocol that's a part of secure scuttlebutt. https://ssbc.github.io/scuttlebutt-protocol-guide/

Hi everyone, I'm having a recurring issue with the "Sign in with Apple" integration in my web app, and I’m hoping someone here can help or share insights. Here’s the situation: I implemented "Sign in with Apple" following the official documentation, and it worked perfectly at first. After about two weeks, I started getting the "invalid_client" error when redirecting to the authentication page. I reviewed everything and discovered I hadn’t set up the email configuration properly in the Apple Developer Console. Once I fixed that, it worked fine again. Now, the same error ("invalid_client") has returned, and I’ve triple-checked every part of my configuration: The service ID, redirect URIs, and domain settings match exactly. The client_secret is generated correctly with all required fields (iss, iat, exp, aud, and sub) and signed with ES256. My server time is synchronized. Nothing has changed in my code or configuration since it last worked. This seems to be an issue on Apple’s end because everything was functioning perfectly before, and I’ve already resolved this once by updating settings in the Developer Console. Has anyone else faced this issue? Is there something I might be missing, or could this be a problem with Apple’s service? Any advice or guidance would be greatly appreciated!

We run simple iOS Swift code triggered by a remote notification: UserDefaults.standard.set("key", forKey: "value") It runs fine when the app is active or inactive, but when the device is closed/locked and the code is triggered, we see a warning in Xcode: Couldn't write values for keys ( key ) in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): Path not accessible Not updating lastKnownShmemState in CFPrefsPlistSource<0x3018802d0> (Domain: com.example, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: No): 767 -> 767 The issue is that there seems to be no way to catch that warning. The value is set, when it's re-read the value is correct. But the value is never written to disk, so after an app restart/update the value is gone, potentially has an old wrong value. This code runs without any interruption, it's just showing the warning on iOS 17.7.1 on iPad: UserDefaults.standard.set("key", forKey: "value") UserDefaults.standard.synchronize() print("value: \(UserDefaults.standard.string(forKey: "key"))") Should there not be a way to catch this, so the code can act accordingly to the circumstances? It would be good to know inside the code that the value is not persisted. I would expect that an exception is generated somewhere which can be caught. It seems .completeFileProtectionUntilFirstUserAuthentication enables files to be written to disk while the device is closed/locked, can something similar be used for UserDefaults.standard?

Hi there, I'm currently working on a compatibility feature for Apple that allows the user to manage their keys and certificates from within our internal API. For this I need to retrieve all the items contained within keychains. I am looking at the documentation for SecItem API but so far I have not really found an obvious way to link these items together. My best guess so far is to perform two queries, grabbing all SecKeys from the keychains, pairing them up with public keys through SecKeyCopyPublicKey, then downloading all CertItems and pairing them with public keys with SecCertificateCopyKey, and then join the two using public keys. This sounds however somewhat involved and I was wondering if there was a better way of going about the process?

Hi, ASCredentialProvider had been almost identically implemented on both iOS and macOS so far, but the ProvidesTextToInsert feature was only added to iOS. It would have been a crucial point to make Credential Providers available in all textfields, without users having to rely on developers correctly setting roles for their Text Fields. It's right now impossible to paste credentials into Notes, or some other non-password text box both in web and desktop apps for example, in a seamless, OS-supported way without abusing Accessibility APIs which are understandably disallowed in Mac App Store apps. Or just pasting an SSH key, or anything. On macOS this has so many possibilities. It could even have a terminal command. It's even more interesting that "Passwords..." is an option in macOS's AutoFill context menu, just like on iOS, however Credential Providers did not gain this feature on macOS, only on iOS. Is this an upcoming feature, or should we find alternatives? Or should I file a feature request? If it's already in the works, it's pointless to file it.

I have an app (currently not released on App Store) which runs on both iOS and macOS. The app has widgets for both iOS and macOS which uses user preference (set in app) into account while showing data. Before upgrading to macOS 15 (until Sonoma) widgets were working fine and app was launching correctly, but after upgrading to macOS 15 Sequoia, every time I launch the app it give popup saying '“Kontest” would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.' and also widgets do not get user preferences and throw the same type of error on Console application when using logging. My App group for both iOS and macOS is 'group.com.xxxxxx.yyyyy'. I am calling it as 'UserDefaults(suiteName: Constants.userDefaultsGroupID)!.bool(forKey: "shouldFetchAllEventsFromCalendar")'. Can anyone tell, what am I doing wrong here?

In our application, we store user information (Username, Password, accessToken, Refresh token, etc.) in the keychain. However, after performing a hard reboot (unplugging and plugging back in), when we attempt to retrieve the ‘refresh token’ or ‘access token’ from the keychain, we receive the old token instead of the newly saved one.

Hi, I use AudioQueueNewInput() with my very own run loop and dedicated thread. But now it doesn't show the mic alert window. Howto fix this? AudioQueueNewInput(&(core_audio_port->record_format), ags_core_audio_port_handle_input_buffer, core_audio_port, ags_core_audio_port_input_run_loop, kCFRunLoopDefaultMode, 0, &(core_audio_port->record_aq_ref));

Hello all - we have enabled our app users to create and sign in using their passkey. However - for some users, we get a NSLocalizedFailure reason exception that the app is not associated with the domain. We have ensured that the endpoint /.well-known/apple-app-site-association isnt blocking any requests. Like I said before, 90% of our users are able to successfully create and sign in with their passkey but we receive the above error for the remaining 10%. Any suggestions/guidance on how we can resolve this would be helpful and greatly appreciated. Thank you.

Hi, I need to make a "Sign with apple" button. I followed all the instructions and I managed to get apple's response with id_token. I have to continue testing the application but I no longer get the "user" object (name, lastname). How can I get the user object back to continue development?

We received a rejection today based on an invalid PrivacyInfo.xcprivacy file. It contained one extra space character was somehow added to a value field. Is there a tool that can check the validity of our PrivacyInfo.xcprivacy files?

Does macos app support passkey? Can I also use passkey's functionality if it's an internal release, not an Apple App Store release?
