Hi, I am developing a Platform SSO in order to have integrated with our IdP, which I am also adapting to provide the right endpoints for Platform SSO. I have a few questions about the implementation: does the client-request-id need to be present on all requests? Is it unique per request, or requests that are bound together like those requesting a nonce and those who will use that nonce should use the same client-request-id? I am not sure how the loginManager.presentRegistrationViewController works. I'd like to get the user to authenticate to my IdP before device registration. So I am not sure if I should provide my own Webview or something similar or if this method should do something for me; My idea is to request user authentication once, save the state when performing device registration, so that I avoid asking for user authentication twice when performing user registration. Is this the right way to do it? How does platform SSO handles tokens? If one application of my IdP requests the authentication on a common OIDC/OAuth2 flow, should I perform some sort of token exchange? How about SAML? Platform SSO seems to be token-centric, but how does one handle SAML flows? Is it by using WebView as well?

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

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!

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 trying to integrate those into my app, stuck on it would not transfer to view that inside app, can someone help? Scott

We are using ASWebAuthenticationSession with apps on IoS to achieve SSO between apps. The IdP for authentication (OIDC) is an on-premise and trusted enterprise IdP based on one of the leading products in the market. Our problem is that the user is prompted for every login (and logouts) with a consent dialogue box: “AppName” wants to use “internal domain-name” to Sign In This allows the app and website to share information about you. Cancel Continue” I have read in various places that Apple has a concept of “Trusted domains” where you can put an “Apple certified” static web-page on the IdP. This page needs to contain specific metadata that iOS can verify. Once a user logs in successfully a few times, and if the IdP is verified as trusted, subsequent logins would not prompt the consent screen. Question: I struggle to find Apple documentation on how to go about a process that ends with this “Apple certified web-page” on our IdP”. Anyone who has experience with this process, or who can point me in some direction to find related documentation?

With the new ios 26 update, certain numbers will be filtered into other inboxes within imessage. What numbers are classified as "known", and will not be moved into these filters. Do they need to be a contact in your phone, or if a business texts you how will that be filtered?

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) ?

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?

Hi, A certificate imported on macOS 15 using the security command with the "non-exportable" option was imported in an exportable state. I would like to know how to change this certificate to be non-exportable. Regards, CTJ

Hi everyone, I’m developing a multiplayer iOS game that uses Multipeer Connectivity for local peer-to-peer networking. I’d like to display user-assigned device names in the UI to help players identify each other during the connection process. In iOS 16 and later, accessing UIDevice.current.name requires the User-Assigned Device Name Entitlement. The documentation states that the entitlement is granted for functionality involving “interaction between multiple devices that the same user operates”. My game is strictly multiplayer, with devices owned by different users, not a single user managing multiple devices. I have a few questions regarding this: Does the requirement for “devices operated by the same user” definitively exclude multiplayer scenarios where devices belong to different players? Can a Multipeer Connectivity-based game qualify for the entitlement in this case? If the entitlement is not applicable, is prompting users to enter custom names the recommended approach for identifying devices in a multiplayer UI? Has anyone successfully obtained this entitlement for a similar multiplayer use case with Multipeer Connectivity? Thanks in advance.

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.

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.

We have been having very high response times in device check device validation service (https://aninterestingwebsite.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?

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://aninterestingwebsite.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.

Hi, my app is receiving all keyboard events through Input Monitoring preference. It completely stopped to work on macOS 15 Sequoia and I have no idea why. Where can I read what has been changed in Input Monitoring? Thanks!

I want to use incrementalUpdates for my app but store always returns false on my iPad with OS18.3.2. I want to know what are th conditions in which store says its unable to perform incrementalUpdates?

Is there a way (in code or on the OAuth2 server/webpage) to specify the desired window size when using ASWebAuthenticationSession on macOS? I haven't found anything, and we would prefer the window to be narrower. For one of our users, the window is even stretched to the full screen width which looks completely broken…
