Attesting Secure Enclave-Generated Keys in a WebAuthn Flow
Hello everyone, I'm working on a project where I intend to use Secure Enclave-based, device-bound private keys within a Webauthn flow. I have the following question: Is it possible to generate private keys in the Secure Enclave with integrated attestation in order to reliably prove to a relying party the authenticity and uncompromised state of the key? If so, I would appreciate details on the implementation—specifically, any prerequisites, limitations, or particular API calls and configuration options that need to be considered. I look forward to any advice, best practices, or pointers to further documentation on this topic. Thank you in advance for your support! Best regards, Alex

Issue Updating User Password via OpenDirectory API with Root Daemon Privileges
Description: I am attempting to use the OpenDirectory API ODRecord.changePassword to change a user's password without needing the old password, given that I have the appropriate permissions. The goal is to ensure that the password change operation bypasses third-party tools such as EDR or eBPF apps that might otherwise intercept commands, as the operation occurs directly via the API. Problem: When invoking the OpenDirectory API from a launch daemon with root privileges, I receive the following error message: Error Domain=com.apple.OpenDirectory Code=4001 "Operation was denied because the current credentials do not have the appropriate privileges." UserInfo={NSUnderlyingError=0x135907570 {Error Domain=com.apple.OpenDirectory Code=4001 "Credential cannot update user's SecureToken" UserInfo={NSDescription=Credential cannot update user's SecureToken}}, NSLocalizedDescription=Operation was denied because the current credentials do not have the appropriate privileges., NSLocalizedFailureReason=Operation was denied because the current credentials do not have the appropriate privileges.} It seems the error is related to SecureToken, and the underlying issue is that the current credentials (even though they are root-level) do not have the necessary privileges to update the SecureToken status for the user. Steps I’ve Taken: Tested the API via a launch daemon running with root privileges. Ensured that Full Disk Access was granted to the daemon, but this did not resolve the issue. Request: Has anyone encountered this specific issue where root privileges are insufficient to update the user password via the OpenDirectory API ? What additional steps or permissions are required for a user password change? Is there a specific API or method to elevate the privileges for modifying SecureToken, or a workaround to overcome this limitation? Any insights or guidance on this issue would be greatly appreciated! Thank you in advance for your help!

What purpose do shared web credentials in a Message Filter Extension serve?
I'm experiencing the same situation as this post from several months ago, which never received an answer to their follow up question. https://forums.developer.apple.com/forums/thread/759255 The documentation for adding a message filter extension says "you must set up shared credentials as described in Shared Web Credentials" (https://developer.apple.com/documentation/sms_and_call_reporting/sms_and_mms_message_filtering/creating_a_message_filter_app_extension) However credentials are not forwarded to the server and calling SecAddSharedWebCredential from within the extension isn't possible. So I don't understand why the documentation states Shared Web Credentials must be set up. After setting them up, then what is expected to happen with them, or what are you supposed to do with them next. The documentation just says to set them up, it doesn't say how/if they are used or how to use them in the specific context of a message filter extension

prepareInterfaceToProvideCredential .oneTimeCode case is not called
Since release of 18.4. prepareInterfaceToProvideCredential .oneTimeCode case is not called and instead prepareInterfaceForUserChoosingTextToInsert() is called. That is the wrong delegate for this case and it causes confusion for the users. Also, some TOTP fields are recognised however, the key icon button is not presented above the keyboard next to TOTP suggestions. I've also tested 18.5 and it has the same issue. provideOneTimeCodeWithoutUserInteraction works just fine.

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!

Verify the Password using the AuthorizationCopyRights
Hi everyone, I’m working on building a passwordless login system on macOS using the NameAndPassword module. As part of the implementation, I’m verifying if the password provided by the user is correct before passing it to the macOS login window. Here’s the code snippet I’m using for authentication: // Create Authorization reference AuthorizationRef authorization = NULL; // Define Authorization items AuthorizationItem items[2]; items[0].name = kAuthorizationEnvironmentPassword; items[0].value = (void *)password; items[0].valueLength = (password != NULL) ? strlen(password) : 0; items[0].flags = 0; items[1].name = kAuthorizationEnvironmentUsername; items[1].value = (void *)userName; items[1].valueLength = (userName != NULL) ? strlen(userName) : 0; items[1].flags = 0; // Prepare AuthorizationRights and AuthorizationEnvironment AuthorizationRights rights = {2, items}; AuthorizationEnvironment environment = {2, items}; // Create the authorization reference [Logger debug:@"Authorization creation start"]; OSStatus createStatus = AuthorizationCreate(NULL, &environment, kAuthorizationFlagDefaults, &authorization); if (createStatus != errAuthorizationSuccess) { [Logger debug:@"Authorization creation failed"]; return false; } // Set authorization flags (disable interaction) AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights; // Attempt to copy rights OSStatus status = AuthorizationCopyRights(authorization, &rights, &environment, flags, NULL); // Free the authorization reference if (authorization) { AuthorizationFree(authorization, kAuthorizationFlagDefaults); } // Log the result and return if (status == errAuthorizationSuccess) { [Logger debug:@"Authentication passed"]; return true; } else { [Logger debug:@"Authentication failed"]; return false; } } This implementation works perfectly when the password is correct. However, if the password is incorrect, it tries to re-call the macOS login window, which is already open. even i though i did not used the kAuthorizationFlagInteractionAllowed flag. This causes the process to get stuck and makes it impossible to proceed. I’ve tried logging the flow to debug where things go wrong, but I haven’t been able to figure out how to stop the system from re-calling the login window. Does anyone know how to prevent this looping behavior or gracefully handle an incorrect password in this scenario? I’d appreciate any advice or suggestions to resolve this issue. Thanks in advance for your help!

Publishing an app with the correct privacy settings
I am a new developer working to publish an app that includes a location tracker but does not collect user location data. I lam developing my app using Thunkable. My initial submission was rejected because opening the app triggered the error message: "This app is missing "NUserTrackingDescription so tracking transparency will fail. Ensure that this key exists in app's info.plist" However when I add in the NUserTrackingDescription it triggers a process by which I have to notify users that their location data is being collected, which is not the case. I am looking for advice on how to re-submit my app with the correct privacy settings that do not trigger the error message received previously.

Binary executable requires Accessibility Permissions in Tahoe
I have a binary executable which needs to be given Accessibility Permissions so it can inject keypresses and mouse moves. This was always possible up to macOS 15 - when the first keypress arrived the Accessibility Permissions window would open and allow me to add the executable. However this no longer works in macOS 26: the window still opens, I navigate to the executable file and select it but it doesn't appear in the list. No error message appears. I'm guessing that this may be due to some tightening of security in Tahoe but I need to figure out what to change with my executable to allow it to work.

Receiving Apple SignIn profile info again after deleting account
We are currently trying to fix a bug when using SignIn with Apple. It appears that on some occasions we are not receiving a user's profile info (name, email) when a new account is created. After doing some investigation we believe this bug is due to the same Apple login being used as an already deleted account. ASF only appears to send profile info the very first time an Apple login is used. If that account is deleted and another is created with the same apple login we won't receive the profile info. As a result we are not in compliance with Apple's guidelines requiring that we use the provided profile info with Apple SigIn, and need to prompt users to enter it again. Is there a process in place to properly "clear" a user after their account is deleted in our system, so that the next time a user creates an account with the same Apple login, we receive their profile info again?

Enhanced Security Capability < iOS 26
Hi, After enabling the new Enhanced Security capability in Xcode 26, I’m seeing install failures on devices running < iOS 26. Deployment target: iOS 15.0 Capability: Enhanced Security (added via Signing & Capabilities tab) Building to iOS 18 device error - Unable to Install ...Please ensure sure that your app is signed by a valid provisioning profile. It works fine on iOS 26 devices. I’d like to confirm Apple’s intent here: Is this capability formally supported only on iOS 26 and later, and therefore incompatible with earlier OS versions? Or should older systems ignore the entitlement, meaning this behavior might be a bug?

Application not getting identified after notarization
Hi folks We have a Developer ID Application which we create using electron. We made our last release for our Application on Nov'24 which was correctly working. Using the same code, we tried creating a notarized application again which started showing the following error while opening our Application. Monterey- M2- When we directly run the dmg on the dev machine, it does not give us the prompt. But if we download it from somewhere and run, the prompt comes up even in dev machine. We executed some commands to verify the notarization: 1- spctl --assess -vv /Applications/Refresh\ Pro.app On both dev machine and non-dev machine, the output was "accepted" /Applications/Refresh Pro.app: accepted source=Notarized Developer ID origin=Developer ID Application: Prograde Digital Incorporated (*******) 2- xcrun stapler validate /Applications/Refresh\ Pro.app On dev machine, we executed this command and the output is as follows. Processing: /Applications/Refresh Pro.app The validate action worked! 3- codesign -vvv --deep --strict /Applications/Refresh\ Pro.app/ /Applications/Refresh Pro.app: valid on disk /Applications/Refresh Pro.app: satisfies its Designated Requirement We have created a bug attaching the dmg. Please suggest anything we can try to make the release out the door. Bug link- https://feedbackassistant.apple.com/feedback/16811025

Enquiry about the Apple DeviceCheck service
Recently, we received an user enquiry regarding the inability to perform bookings for the app. After investigation, we found that the issue appears to be caused by the failure of the Apple DeviceCheck service. Based on our checks, approximately 0.01% of requests fail each day (e.g., on 26 June: 6 failures out of 44,544 requests) when using Apple DeviceCheck. Could you please assist in raising the following enquiries with Apple Support? What is the typical failure rate of Apple DeviceCheck? Are there any reliability metrics or benchmarks for its performance? How can the failures be prevented, or is there a recommended retry mechanism to handle such failures? Does the iOS version affect the performance or reliability of Apple DeviceCheck? Are there known issues or limitations with specific iOS versions? How long does the token remain valid, and when should a new one be retrieved? Does using a jailbroken device affect the functionality of Apple DeviceCheck?

Accessing the key generated by DCAppAttestService
Hi, is it somehow possible to access a key that was generated by the DCAppAttestService generateKey() function? I need to be 100% sure that no actor from within or outside of my app can access the generated key with the DeviceCheck Framework. It would also be helpful to get some official resources to the topic. Thank you in advance, Mike

Question: Best Practice for Storing API Keys in iOS Apps (RevenueCat, PostHog, AWS Rekognition, etc.)
Hi everyone, I’m looking for clarification on best practices for storing API keys in an iOS app — for example, keys used with RevenueCat, PostHog, AWS Rekognition, barcode scanners, and similar third-party services. I understand that hard-coding API keys directly in the app’s source code is a bad idea, since they can be extracted from the binary. However, using a .plist file doesn’t seem secure either, as it’s still bundled with the app and can be inspected. I’m wondering: What are Apple’s recommended approaches for managing these kinds of keys? Does Xcode Cloud offer a built-in or best-practice method for securely injecting environment variables or secrets at build time? Would using an external service like AWS Secrets Manager or another server-side solution make sense for this use case? Any insights or examples of how others are handling this securely within Apple’s ecosystem would be greatly appreciated. Thanks for considering my questions! — Paul

Apple Sign-In Private Relay Issue Across Two Organizations
Hello Apple Developer Support, I am experiencing an issue with Apple Sign-In and Private Relay across two separate organizations. I have a web application that supports Apple Sign-In, configured under organization ID: 62P86SVLK4. Users can log in using their Apple accounts with the Hide My Email (Private Relay) feature enabled. This web application was created a long time ago and initially only had a web component. Recently, we developed a native mobile version of this application, which also supports Apple Sign-In. However, due to business constraints, the mobile application was created under a different organization ID: T6JT35U9NW. The Issue Since the web and mobile applications are registered under different organizations, accounts created using Apple Sign-In with Private Relay are not recognized across both applications. For example: A user creates an account in the web app using Apple Sign-In with Private Relay. When they attempt to log in to the mobile app with Apple Sign-In (also using Private Relay), authentication fails because the generated Private Relay email addresses do not match between the two organizations. Question Is there any way to link Private Relay accounts across these two organizations so that users who signed up on the web application can log in to the mobile application seamlessly? I appreciate any guidance on how to resolve this issue. Best regards, Kamil Gronert

Password AutoFill doesn't work - help needed
I have a project with a single app target that serves two environments, and two schemes, one for each env, using xcconfig files for defining environment-specific stuff. I'm trying to figure this out for months, so I've tried multiple approaches throughout this period: Have a single domain in "Associated domains" in Xcode, defined as webcredentials:X where X gets replaced using a value from xcconfig. Have two domain entries in "Associated domains" webcredentials:PROD_DOMAIN and webcredentials:STAGING_DOMAIN. Have a different order of domains Results are very interesting: whatever I do, whatever approach I take, password autofill works on staging, but doesn't work on production. I'm aware that we need to test production on Test Flight and AppStore builds. That's how we're testing it, and it's not working. Tested on multiple devices, on multiple networks (wifi + mobile data), in multiple countries.. you name it. The server side team has checked their implementation a dozen times; it's all configured properly, in the exact same way across environments (except bundle ID, ofc). We tried a couple websites for validating the apple-app-site-association file, and while all of those are focused on testing universal links, they all reported that the file is configured properly. Still, password autofill doesn't work. I prefer not to share my app's domains publicly here. Ideally I would contact Apple Developer Support directly, but they now require a test project for that, and since 'a test project' is not applicable to my issue, I'm posting here instead.

Xcode SwiftUI Preview "app" wants to access data from other app
I am writing SwiftData app, using a group container. When editing a SwiftUI file, every couple of seconds a dialog - that the app wants to access data from other apps - pops up. It is impossible to edit a view file while Canvas preview is open. If preview is resumed the dialog has to be confirmed twice. Each time the app is started from Xcode, the dialog has to be confirmed again. Any idea, how to stop these boring dialogs?
