[Resolved] Sign in with Apple Service Outage: Wednesday, June 18, 2025 - Monday, June 23, 2025
On Wednesday, June 18, 2025, Sign in with Apple was impacted by a configuration issue which affected some developer accounts that created new app or Services ID configurations, or edited existing configurations, resulting in the following errors: invalid_client response error returned by the authentication, token validation/revocation, and user migration requests "Sign Up Not Completed" (or equivalent) error presented from the Authentication Services framework. On Monday, June 23, 2025, this issue was resolved. Please retry the Sign in with Apple flows in your Sign in with Apple enabled apps and websites to confirm your developer account configuration has been fixed. Please let us know if you can still reproduce this issue with your developer account. If so, follow the steps outlined in the post below: Gathering required information for troubleshooting Sign in with Apple authorization and token requests https://developer.apple.com/forums/thread/762831 Finally, reply (not comment) with your Feedback ID on either of the posts below: https://developer.apple.com/forums/thread/789011 https://developer.apple.com/forums/thread/789132 Cheers, Paris X Pinkney |  WWDR | DTS Engineer

Unable to give permission to app I'm building to access devices on local network on Sequoia - no prompt given
I am developing apps using NWJS framework, which access devices on the local network. I am doing this on Sequoia on Macos (Desktop). I have developed other apps using NWJS before, but on earlier versions of Macos. My issue is, I am unable to give my app permission to app to access devices on local network on one of the apps. Some background: Other apps which I have used which access devices on the local network, on first-time launching, have given a prompt asking me if I want to allow or deny access to local device for the app. However, on first-time launching (and many others after that), It simply says the device cannot be reached, and I never get a prompt asking me if I want to allow or deny access to local device for my app. In its barebones proof-of-concept stage of my app, I have an iframe who's src attribute is the IP address of a device known on the network with that address. I have tried the protocol https://192.168.1.99 and http://192.168.1.99 in the src attribute. This protocol works in another app I have built where upon first-time launch, I was able to get a prompt and give it the needed permission. If I check in System Settings > Privacy and Security > Network, the app doesn't appear where I can toggle a setting. I also am unable to explicitly add my app to the list. ** This worked for one app, but not another: In researching this issue, it was recommended that I add the following keys in info.plist: com.apple.developer.networking.multicast - boolean true NSLocalNetworkUsageDescription - string description NSNearbyInteractionUsageDescription - string description This worked for one of my apps, but not another, which has a nearly identical structure. In fact, other than CFBundleIdentifier, CFBundleDisplayName and CFBundleName, info.plist is identical. Why did this work one time, and how can I get my app to prompt for permission for local network access?

Empty userID for cross-platform attestation with Android
I've come across strange behavior with the userID property on the returned credential from a passkey attestation. When performing a cross-device passkey assertion between iOS and Android by scanning the generated QR code on my iPhone with an Android device the returned credential object contains an empty userID. This does not happen when performing an on device or cross-device assertion using two iPhones. Is this expected behavior, or is there something I'm missing here? I couldn't find any more information on this in the documentation. iOS Version: 26.0.1, Android Version: 13

SFAuthorizationPluginView and invalid password
I am using SFAuthorizationPluginView in my Security agent plugin. My code expects that its willActivate method be called. With normal screensaver unlock, this works fine. However if I enter an invalid password, then enter the correct password, I never get the willActivate call. I have reproduced this with Quinn's LoginUIAuthPlugin from the QAuthPlugins example code. My mechanisms look like this with LoginUIAuthPlugin: mechanisms HyprAuthPlugin:invoke builtin:authenticate,privileged PKINITMechanism:auth,privileged LoginUIAuthPlugin:login CryptoTokenKit:login I would like to be able to get my plugin working properly when the user had previously entered an invalid password.

Handling ITMS-91061: Missing privacy manifest
An ITMS-91061: Missing privacy manifest rejection email looks as follows: ITMS-91061: Missing privacy manifest- Your app includes "<path/to/SDK>", which includes , an SDK that was identified in the documentation as a privacy-impacting third-party SDK. Starting February 12, 2025, if a new app includes a privacy-impacting SDK, or an app update adds a new privacy-impacting SDK, the SDK must include a privacy manifest file. Please contact the provider of the SDK that includes this file to get an updated SDK version with a privacy manifest. For more details about this policy, including a list of SDKs that are required to include signatures and manifests, visit: https://developer.apple.com/support/third-party-SDK-requirements. Glossary ITMS-91061: Missing privacy manifest: An email that includes the name and path of privacy-impacting SDK(s) with no privacy manifest files in your app bundle. For more information, see https://developer.apple.com/support/third-party-SDK-requirements. : The specified privacy-impacting SDK that doesn't include a privacy manifest file. If you are the developer of the rejected app, gather the name of the SDK from the email you received from Apple, then contact the SDK's provider for an updated version that includes a valid privacy manifest. After receiving an updated version of the SDK, verify the SDK includes a valid privacy manifest file at the expected location. For more information, see Adding a privacy manifest to your app or third-party SDK. If your app includes a privacy manifest file, make sure the file only describes the privacy practices of your app. Do not add the privacy practices of the SDK to your app's privacy manifest. If the email lists multiple SDKs, repeat the above process for all of them. If you are the developer of an SDK listed in the email, publish an updated version of your SDK that includes a privacy manifest file with valid keys and values.

ASAuthorizationPlatformPublicKeyCredentialAssertion.signature algorithm
Hello everyone. Hope this one finds you well) I have an issue with integrating a FIDO2 server with ASAuthorizationController. I have managed to register a user with passkey successfully, however when authenticating, the request for authentication response fails. The server can't validate signature field. I can see 2 possible causes for the issue: ASAuthorizationPlatformPublicKeyCredentialAssertion.rawAuthenticatorData contains invalid algorithm information (the server tries ES256, which ultimately fails with false response), or I have messed up Base64URL encoding for the signature property (which is unlikely, since all other fields also require Base64URL, and the server consumes them with no issues). So the question is, what encryption algorithm does ASAuthorizationController use? Maybe someone has other ideas regarding where to look into? Please help. Thanks)

Backup Eligibility and Backup State has set to true for support hybrid transport with legacy authenticators
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?

AASA not being fetched immediately upon app install
Hi Apple Devs, For our app, we utilize passkeys for account creation (not MFA). This is mainly for user privacy, as there is 0 PII associated with passkey account creation, but it additionally also satisfies the 4.8: Login Services requirement for the App Store. However, we're getting blocked in Apple Review. Because the AASA does not get fetched immediately upon app install, the reviewers are not able to create an account immediately via passkeys, and then they reject the build. I'm optimistic I can mitigate the above. But even if we pass Apple Review, this is a pretty catastrophic issue for user security and experience. There are reports that 5% of users cannot create passkeys immediately (https://developer.apple.com/forums/thread/756740). That is a nontrivial amount of users, and this large of an amount distorts how app developers design onboarding and authentication flows towards less secure experiences: App developers are incentivized to not require MFA setup on account creation because requiring it causes significant churn, which is bad for user security. If they continue with it anyways, for mitigation, developers are essentially forced to add in copy into their app saying something along the lines of "We have no ability to force Apple to fetch the config required to continue sign up, so try again in a few minutes, you'll just have to wait." You can't even implement a fallback method. There's no way to check if the AASA is available before launching the ASAuthorizationController so you can't mitigate a portion of users encountering an error!! Any app that wants to use the PRF extension to encrypt core functionality (again, good for user privacy) simply cannot exist because the app simply does not work for an unspecified amount of time for a nontrivial portion of users. It feels like a. Apple should provide a syscall API that we can call to force SWCD to verify the AASA or b. implement a config based on package name for the app store such that the installation will immediately include a verified AASA from Apple's CDN. Flicking the config on would require talking with Apple. If this existed, this entire class of error would go away. It feels pretty shocking that there isn't a mitigation in place for this already given that it incentivizes app developers to pursue strictly less secure and less private authentication practices.

Are some backgrounded apps allowed to record phone calls but not others?
It’s been established that generally speaking background apps cannot record audio while the foreground app is already reading audio data from the microphone, but are there exceptions? For instance, is there an exception for certain Apple apps? If so, and there’s a special exception that most programmers don’t know about but some Apple’s engineers do and perhaps some hackers do as well, wouldn’t the mechanism that allows that eventually be exploited?

Webview In-App Browser Microsoft Login Redirection Not Working
Hello, We received a rejection on one of our IOS applications because we were doing Microsoft MSAL login through the user's browser. The representative recommended that we use Webview to do in-app logins. However when we tried to handle the custom app uri redirection (looking like myapp://auth/), Webview does not seem to send the user back to the application. Does anyone have a fix for this? Thanks!

Anti-**** Apps Need Solutions to iOS Sandbox Restrictions
Hello everyone, I’ve been working on ways to implement stricter accountability systems for personal use, especially to prevent access to NSFW content in apps like Reddit and Twitter. The main challenge is that iOS sandboxing and privacy policies block apps from monitoring or interacting with other apps on the system. While Apple’s focus on privacy is important, there’s a clear need for an opt-in exception for accountability tools. These tools could be allowed enhanced permissions under stricter oversight to help users maintain accountability and integrity without compromising safety. Here are a few ideas I’ve been thinking about: 1. Vetted Apps with Enhanced Permissions: Allow trusted applications to bypass sandbox restrictions with user consent and close monitoring by Apple. 2. Improved Parental Controls: Add options to send notifications to moderators (like accountability partners) when restrictions are bypassed or disabled. 3. Custom Keyboard or API Access: Provide a framework for limited system-wide text monitoring for specific use cases, again with user consent. If anyone has ideas for how to address this within current policies—or suggestions for advocating for more flexibility—I’d appreciate the input. I’m curious how others have handled similar challenges or if there are better approaches I haven’t considered.

Outlook for Mac add-in - Passkeys
hello, My organization has an outlook add-in that requires auth into our platform. As Microsoft forces Auth on MacOS to use WKWebView https://learn.microsoft.com/en-us/office/dev/add-ins/concepts/browsers-used-by-office-web-add-ins, we are running into a situation that we cannot use passkeys as an auth method as we are unable to trigger WebAuthN flows. We’ve raised this in Microsoft side but they have deferred to Apple given WKWebView is Safari based. This is a big blocker for us to achieve a full passwordless future. Has anyone come across this situation? Thank you.

Impact of SIWA App transfer on migration on relay emails
Hello, we're currently evaluating the side effects of transferring our app to a different Apple developer account. Our users use SIWA to sign in to our platform which uses Auth0. As I understand it, the identifiers provided by Apple will change, and as such Auth0 will not recognise them and treat them as new users. I've read conflicting documentation, reports, discussions, etc, so it would be great if I could get some clarification on the topic. Furthermore we're concerned about the Hide My Email functionality. A lot of our users use this feature. Will the relay email for each user change with the transfer? If so, does the 'old' relay email stop working as soon as the transfer happens? Thanks in advance!

Shared Device Mode iPad Passcode Reset Duration
I was wondering if anyone had experience with Managed Device Profiles on iPad to be able to answer a quick question regarding passcode reset. We are using Microsoft Intune to manage our fleet of iPads that our store employees will use on an Ad-Hoc basis. When a user logs into an iPad for the day, we are issuing a resetPasscode command to the MicrosoftGraph specifying that device ID. We are getting a successful response to the iPad itself. But the device is allowing the user 1 hour of free time to dismiss the reset passcode dialogue. Which enables them to use the iPad unprotected for up to an hour, which is not what we want. Does anyone know of any way to force the user to select a passcode immediately? I know this is a device side restriction. But is there anything apple can do to help us in this instance, since our MDM profile can't close this time window on the Intune side?
