Hi,
I am developing an app that checks if biometric authentication capabilities (Face ID and Touch ID) are available on a device. I have a few questions:
Do I need to include a privacy string in my app to use the LAContext's canEvaluatePolicy function? This function checks if biometric authentication is available on the device, but does not actually trigger the authentication.
From my testing, it seems like a privacy declaration is only required when using LAContext's evaluatePolicy function, which would trigger the biometric authentication. Can you confirm if this is the expected behavior across all iOS versions and iPhone models?
When exactly does the biometric authentication permission pop-up appear for users - is it when calling canEvaluatePolicy or evaluatePolicy? I want to ensure my users have a seamless experience.
Please let me know if you have any insights on these questions. I want to make sure I'm handling the biometric authentication functionality correctly in my app. Thank you!

I am having trouble with one of my apps that will not let me log in via Apple Sign In. I am using Firebase and Firebase UI for the sign in process. I have many other apps with the same exact config that currently work just fine, but this one I have gone as far as completely deleting the targets and rebuilding and it will not return from the login screen
I checked the following:
Sign in with Apple ID Capability is available in XCode and on the dev certificate on developer.apple.com
I have also toggled both of them on and off.
I have double checked the config in Firebase to turn on the Apple Login identifier. Again I have toggle it on and off.
I have cleaned the project multiple times to no avail.
I have logged out and back into my developer account in XCode.
It seams like after I put in the correct password to log in, it just never returns to the app, there is no logging. I do get a notified(shaking input box) if I put in an incorrect password, but when I put in the correct one, the login window never dismisses and my app is not notified.
I checked the Console and the last message from akd on a working app is:
Notifying client (bundle) of credential state change 1.
Remote view sent a finish event
On the one not working, using the same user and password akd returns:
SRP authentication with server failed! Error: Error Domain=com.apple.AppleIDAuthSupport Code=2 "M2 missing (bad password)
I have 100% verified I am putting in the correct user password. I was only notified of this issue because Policy is having the same issue logging in during App Review. Also, if I put in a bad password the input window shakes and when this is happening, the input window is not shaking
Hello.
I have issue with implementing "Sign in with Apple" on my website.
As folow, I have created:
App ID identifier: com.livnobus.app (G2F5N5UHYZ)
Service ID identifier: com.livnobus.client (B25ZN8P84U) with option enabled "Sign in with Apple" and configuration (Primary App ID and Webiste URLs)
Key ID: 43N8XKUW7S with option enabled "Sign in with Apple" and configuration (Primary App ID and Grouped App Ids)
When I click "Sign in with Apple" on my website (https://dev.livnobus.com/auth/login), system redirect me to https://appleid.apple.com/ and error show "invalid_client".
Redirect URL on my web site is:
https://appleid.apple.com/auth/authorize?client_id=com.livnobus.client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO
There was old Service ID identifier com.livnobus.app-client, for which I lost private KEY, so I have created new one: com.livnobus.client
With old Service ID com.livnobus.app-client, https://appleid.apple.com/ shows me Apple form for sign in, but with new Service ID com.livnobus.client there is error "invalid_client"
https://appleid.apple.com/auth/authorize?client_id=com.livnobus.app-client&redirect_uri=https%3A%2F%2Fdev.livnobus.com%2Fauth%2Fapple%2Fcallback&scope=name%20email&response_type=code&response_mode=form_post&state=eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO&nonce=e7c7a242-1977-47ea-9013-98820c24bfba.eGAgdpLrvskJc26RbTizc9TGwxnL6KAEJOf68pmO
These changes I have made last Friday, and since then I can't use "Sign in with Apple" on my website.
Thanks!
I’m implementing a custom Authorization right with the following rule:
<key>authenticate-user</key>
<true/>
<key>allow-root</key>
<true/>
<key>class</key>
<string>user</string>
<key>group</key>
<string>admin</string>
The currently logged-in user is a standard user, and I’ve created a hidden admin account, e.g. _hiddenadmin, which has UID≠0 but belongs to the admin group.
From my Authorization Plug-in, I would like to programmatically satisfy this right using _hiddenadmin’s credentials, even though _hiddenadmin is not the logged-in user.
My question:
Is there a way to programmatically satisfy an authenticate-user right from an Authorization Plug-in using credentials of another (non-session) user?
Hi, I've been developing an app with a server. I'm hosting the server on an IPv6-ONLY network that's hidden behind the CloudFlare, so it works flawlessly from the clients point of view, but if server needs to access external resources, they need to be accessible over IPv6. As it turns out, appleid.apple.com doesn't support IPv6, and the Sign In with Apple happens with the help of my server.
So, I can't sign users in as Apple doesn't support IPv6 traffic on appleid.apple.com. Are there any plans to support IPv6 in the near future, or should I work on the networking setup to enable IPv4 just for the Apple SSO? Or maybe there's a clever workaround I'm missing?

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 am implementing Apple Sign-In for a multi-platform application, specifically for the web component using the REST API flow.
I am encountering an invalid_request Invalid web redirect url error when attempting to use a newly registered redirect URL.
Here are the details:
Original Test URL: I initially registered a redirect URL, let's call it [Your Original Test Redirect URL, e.g., https://test.yourdomain.com/auth/callback], for testing purposes. This URL worked correctly.
New Service URL: I then registered a second redirect URL, [Your New Service Redirect URL, e.g., https://www.yourdomain.com/auth/callback], intended for my production service. This URL was registered approximately 5 days ago (including the weekend).
The Problem: The new service URL ([Your New Service Redirect URL]) is still not working and consistently returns the invalid_request Invalid web redirect url error.
Puzzling Behavior: Furthermore, I have since deleted the original test URL ([Your Original Test Redirect URL]) from the Service ID configuration in the Apple Developer portal. However, the deleted test URL still appears to function correctly when I use it.
This situation is highly confusing: The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational.
The Service ID in question is [Your Service ID, e.g., com.yourdomain.service].
Could you please investigate why the new redirect URL ([Your New Service Redirect URL]) is not becoming active and is returning the invalid_request error, and also explain why the deleted URL ([Your Original Test Redirect URL]) remains functional?
Any guidance or assistance you can provide to resolve this issue with the new URL would be greatly appreciated. Thank you for your time and support.
Sincerely,
I have the exact same problem.
The newly registered URL is not working after 5 days, while the URL I have deleted from the configuration is still operational.
In addition to the above problem, I also get a response of 'invalid_client' when I newly register a service in configuration.
Please check it out as it needs to be resolved quickly.
What Has Been Implemented
Replaced the default loginwindow:login with a custom authorization plugin.
The plugin:
Performs primary OTP authentication.
Displays a custom password prompt.
Validates the password using Open Directory (OD) APIs.
Next Scenario was handling password change
Password change is simulated via: sudo pwpolicy -u robo -setpolicy "newPasswordRequired=1"
On next login:
Plugin retrieves the old password.
OD API returns kODErrorCredentialsPasswordChangeRequired.
Triggers a custom change password window to collect and set new password.
Issue Observed : After changing password:
The user’s login keychain resets.
Custom entries under the login keychain are removed.
We have tried few solutions
Using API, SecKeychainChangePassword(...)
Using CLI, security set-keychain-password -o oldpwd -p newpwd ~/Library/Keychains/login.keychain-db
These approaches appear to successfully change the keychain password, but:
On launching Keychain Access, two password prompts appear, after authentication, Keychain Access window doesn't appear (no app visibility).
Question:
Is there a reliable way (API or CLI) to reset or update the user’s login keychain password from within the custom authorization plugin, so:
The keychain is not reset or lost.
Keychain Access works normally post-login.
The password update experience is seamless.
Thank you for your help and I appreciate your time and consideration

Hello Experts,
I am in need of your help with this feedback from the App Reviewer.
Issue Description: One or more purpose strings in the app do not sufficiently explain the use of protected resources. Purpose strings must clearly and completely describe the app's use of data and, in most cases, provide an example of how the data will be used.
Next Steps: Update the location purpose string to explain how the app will use the requested information and provide a specific example of how the data will be used. See the attached screenshot.
Resources: Purpose strings must clearly describe how an app uses the ability, data, or resource. The following are hypothetical examples of unclear purpose strings that would not pass review:
"App would like to access your Contacts"
"App needs microphone access"
Feedback #2
"Regarding 5.1.1, we understand why your app needs access to location. However, the permission request alert does not sufficiently explain this to your users before accessing the location.
To resolve this issue, it would be appropriate to revise the location permission request, specify why your app needs access, and provide an example of how your app will use the user's data.
To learn more about purpose string requirements, watch a video from App Review with tips for writing clear purpose strings. We look forward to reviewing your app once the appropriate changes have been made."
May I know how can I update my purpose string? I appealed on the first feedback by explaining what is the purpose of it but got the Feedback #2.
TYIA!!
Since a few days, we are hitting AuthorizationError 1000 / 1001 whenever we try to use Sign in with Apple for a new app. We have added entitlements to the app in both release and debug, and setup the services id.
Many other devs are complaining about the same issue lately, and it's possible to reproduce on a fresh app id, see this thread:
https://www.reddit.com/r/flutterhelp/comments/1lf6kmq/sign_in_with_apple_signup_not_completed
We're integrating Sign in with Apple into our iOS app using both SwiftUI and UIKit.
The Apple ID login UI appears correctly on real devices, but after tapping Continue, the system immediately stops and shows code 1001.
This issue happens across multiple devices and Apple ID accounts, even with no prior login history.
We’ve confirmed the following:
Sign in with Apple is enabled in both Developer Portal and Xcode Capabilities
Automatic signing and provisioning are set correctly
Device is signed into iCloud and system time is synced
Performed clean build, app reinstall, and other standard debugging steps
We suspect that the sign-in process may not be completing properly due to some kind of account or server-side restriction, and we’d appreciate any insights into this behavior.
I am asking about the apple Sign in implementation.
▫️ problems
eas local build or test flight, I get a “Could not complete registration” message.
When I check the console, I see the following error message.
akd SRP authentication with server failed! Error: Error
Domain=com.apple.AppleIDAuthSupport Code=2
UserInfo={NSDescription=<private>, Status=<private>}
▫️ Assumption
・Developed with Expo
・"expo-apple-authentication":"^7.2.4"
・Two apps are developed at the same time, using supabase, firebase, but both have the same error
・On Xcode, on app ids, apple sign in capability is turned on
・Service ids is set to domain, return url
・keys is created
・Internal test of testfligt is set to deliver

Authentication Services
I'm developing a Unity iOS app using the official "Sign In with Apple" Unity plugin (v1.5.0), and I'm encountering persistent errors during authentication. Here’s the full context:
App Info:
Unity version: 6000.0.32f1
Bundle ID: com.pfcgaming.applesignin
Sign In with Apple enabled in the Apple Developer portal
Real iOS device, not simulator
Error Logs:
txt
Copy
Edit
Authorization failed: Error Domain=AKAuthenticationError Code=-7003 "(null)"
UserInfo={AKClientBundleID=com.pfcgaming.applesignin}
ASAuthorizationController credential request failed with error:
Error Domain=com.apple.AuthenticationServices.AuthorizationError Code=1001 "(null)"
Description: The operation couldn’t be completed. No credentials available for login.
What I’ve Done So Far:
Verified "Sign In with Apple" is enabled under the App ID in developer.apple.com.
Provisioning profile has been regenerated with correct entitlements.
Xcode project has the “Sign In with Apple” capability added.
Tested on multiple real iOS devices with iCloud + Keychain enabled.
Tried both PerformQuickLogin() and LoginWithAppleId() approaches in the plugin.
My Observations:
These errors started occurring right after enabling "Sign In with Apple" in the developer portal.
Based on some community feedback, there may be a backend propagation delay after enabling SIWA (Sign In With Apple) which might cause these errors.
Questions:
Is it expected to receive error -7003 or 1001 immediately after enabling SIWA in the Developer Portal?
How long does it typically take for entitlement changes to fully propagate?
Is there any Apple-recommended workaround to test during this wait time?
Any insight or confirmation would be helpful. Thanks in advance!

Sign in with Apple
Hello,
I'm developing an iOS app that includes a Sign In with Apple feature.
I’ve completed the following setup steps:
Enabled Sign In with Apple for the app’s Bundle ID in the Apple Developer Console.
Added Sign In with Apple capability in Xcode under Signing & Capabilities.
Tested the feature on a real device, not a simulator.
Registered the real device ID in the Developer Console just in case any hidden permission issues exist.
Despite following all the necessary steps (and even using the official Apple sample code) the Sign In bottom sheet displays a "Sign Up Not Completed" message. Unfortunately, I don’t receive any further error details to help diagnose the issue.
After searching through StackOverflow and this forum, I came across posts suggesting that the feature might take up to 48 hours to become active after setup. Is this still the case in 2025? Or is there something I might be missing?
For additional context: other features such as APNs (Push Notifications) are working as expected.
Thank you in advance for any help or insight!

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.
When implementing Sign In with Apple I created an App ID and a Service ID for my app. I didn't configure the Server-to-Server Notification URL properly there and token revocation didn't work.
Later on I updated the url config and the name of the identifiers. However, when I Sign in with Apple in my app I still see the old identifier name in my iPhone Settings->Apple Account->Sign in with Apple. I would assume that if the name doesn't update, the configuration doesn't update either.
I'm using automatic Xcode signing, I have deleted all the profiles locally, cleaned project, bumped versions, waited for a week, nothing worked.
Token revocation for account deletion doesn't work properly I would assume because of the initial misconfiguration. I want to mention that this is working fine for my development build (another bundleID, AppID, ServiceID)
What am I missing here?

Hello, I am at wits' end with the Apple Sign-in api. I have tested in stage and it works beautifully, but when i push to production it gives me the error "invalid_client".
I'm confident the setup is correct, when I asked Apple for help over the phone, they sent me a few forums with no answers.
Has anyone had the same issue? How did you resolve?
Could it be because I have two app IDs and two service IDs? (prod + stage)
