The Passwords App is accessing websites found in the ASCredentialIdentityStore associated with a 3rd Party password management app (SamuraiSafe). This behaviour appears to be associated with looking up website favicons in order to display in Passwords. However the websites contacted are not stored in the Passwords App/iCloud KeyChain - only the 3rd Party password management app (SamuraiSafe). This is effectively leaking website information stored in the 3rd Party password management app.
I first noticed this behaviour on macOS, and it appears to happen every 8 days. Today it was seen on iOS.
The behaviour is revealed through the App Privacy Report on iOS (and LittleSnitch on macOS).
I would not be surprised to see the Passwords App do this for websites saved in the Passwords App/iCloud KeyChain, however I believe it should not be arbitrarily testing every website found in the ASCredentialIdentityStore as reference to that website url should be entirely under the control of the end user.
See attached screenshots from App Privacy Report.

I read online that there is no way to extract the call log from an iPhone. I want to develop an app to help people remember to call their mom, and if they did, the "nagging" would disappear automatically. I'm looking for any workaround to know when a user called someone, without having them log it manually.
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.
The header documentation for the (deprecated) LAContext.evaluatedPolicyDomainState property contains the following:
@warning Please note that the value returned by this property can change exceptionally between major OS versions even if the state of biometry has not changed.
I noticed that the documentation for the new LAContext.domainState property does not contain a similar warning. I also found this related thread from 2016/17.
Is the domainState property not susceptible to changes between major OS versions? Or is this generally not an issue anymore?
Hello everyone,
We recently transferred our iOS app from one Apple Developer account to another, and after the transfer, we encountered a serious issue where all previously stored Keychain data and the local database became inaccessible.
As a result, all users are automatically logged out and lose access to their locally stored data (such as chat history) once they update to the new version signed with the new Team ID.
We understand that Keychain items are tied to the App ID prefix (Team ID), which changes during an app transfer. However, we’re looking for possible workarounds or best practices to avoid user data loss.
Questions:
Is there any reliable method to maintain or migrate access to old Keychain data after an app transfer?
Would reverting the app back to the original developer account and releasing an update from there (to persist or migrate data) before transferring it again be a viable solution?
Has anyone faced a similar issue and found a practical way to handle data persistence during an app transfer?
Any guidance, technical suggestions, or shared experiences would be highly appreciated. This issue is causing major impact for our users, so we’re hoping to find a safe and supported approach.
Thank you,
Mohammed Hassan
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.
转让app成功了之后,由于开发者账号更改,团队ID改变,导致获取不到原有的keychain中缓存的用户数据,所以在用户进行登录时,无法登录到原有的老账号,而是被识别成了一个新的用户。这种情况怎么解决。
I must be missing something. How can an iphone that is in lockdown mode, using ONLY data, no Bluetooth connected and only one singular iPhone have seven UNLISTED items on the local network in privacy and settings?
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.

I'm trying to use ASWebAuthenticationSession on macOS but there is a weird crash and I have no idea what to do.
It looks like there is a main thread check in a framework code that I have no control over.
Any help would be appreciated.
Thank you in advance.
The stack of crashed thread has no symbols, even for supposedly my code in OAuthClient.authenticate.

In response to inquiries from users, we have confirmed the following phenomenon.
If you select "Private email address" in the flow of new user registration with Apple ID, you will not receive the verification code email when performing two-factor authentication.
■User impact
If you use your Apple ID to link an external account without making your email address public, you will not receive the authentication code during two-factor authentication and will not be able to proceed. The date and time of the impact is currently unknown.
◎Impact 1: New registration
If you select "Private email address" in the flow of registering a new user with Apple ID, the verification code will not be received during two-factor authentication and registration will not be completed.
◎Impact 2: Login of existing account
When two-factor authentication is required for an existing account registered with Apple ID set to "Private email address," the verification code is not received and the user cannot log in.
→If you have not registered a login method other than Apple ID for the relevant account, there is no other way to log in.
■About workarounds
・I thought that I could avoid this issue by canceling the private setting of my Apple ID, but I was unable to do so.
→There is currently no workaround found for existing users who are experiencing this issue.
・However, the scope of influence is limited.
■Cause investigation status
Premise: For an Apple ID whose email address is not made public, the two-factor authentication authentication code email follows the following route.
①CDC/GIGYA
miraiz-persol.jp (SendGrid)
Apple's email server (relay server to hide the user's real email address)
User mailbox
→Since '1' are working, the problem seems to have occurred after the connection from ② or ③.
(At this stage, we cannot determine who is at fault: the user, MIRAIZ, or Apple. We are currently investigating.)
◎Hypothesis
・Is there something wrong with Apple's mail server?
・Is it not delivered because the user's mailbox is full?
■Questions, research, and responses we would like to receive
Please check the following two points and reply.
1st point
As shown in the attached image, there seems to be no problem with the SPF settings.
Is it possible to check to see if any errors have occurred with Apple's mail server?
2nd point
Are there any cases where you still can't receive emails even if you deactivate your Apple ID?
I would like to know if there are any patterns in which emails are not being delivered in terms of past inquiries or overall specifications

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
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?
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!!
Hi everyone,
I'm looking for a way to configure Passkey on iOS so that authentication is only possible using FaceID or TouchID. Specifically, I want to disable the use of passcodes and QR codes for authentication. Additionally, is there a method to detect if the authentication was done using a passcode or QR code?
Thanks for your help!
Hello,
Is there any way to detect if the iOS screen is currently being shared via FaceTime or iPhone Mirroring?
Our application relies on this information to help ensure that users are not accessing it from one location while physically being in another.
Hi Team,
How can we fetch the macOS password requirement(for setting a new password) that are inforce during login for users? Is there a way to get this info in swift programming?
I’d like to confirm something regarding the hosting of the apple-app-site-association (AASA) file.
We have a server that publicly hosts the AASA file and is accessible globally. However, this server sits behind an additional security layer (a security server/reverse proxy).
My question is:
Will this security layer affect Apple’s ability to access and validate the AASA file for Universal Links or App Clips?
Are there specific requirements (e.g. headers, redirects, TLS versions, etc.) that we need to ensure the security server does not block or modify?
Any guidance or best practices would be appreciated.
Thanks!
Hi Forum,
We’re building a security-focused SDK for iOS that includes SIM Binding and SIM Swap detection to help prevent fraud and unauthorised device access, particularly in the context of banking and fintech apps.
We understand that iOS limits access to SIM-level data, and that previously available APIs (such as those in CoreTelephony, now deprecated from iOS 16 onwards) provide only limited support for these use cases.
We have a few questions and would appreciate any guidance from the community or Apple engineers:
Q1. Are there any best practices or Apple-recommended approaches for binding a SIM to a device or user account?
Q2. Is there a reliable way to detect a SIM swap when the app is not running (e.g., via system callback, entitlement, or background mechanism)?
Q3. Are fields like GID1, GID2, or ICCID accessible through any public APIs or entitlements (such as com.apple.coretelephony.IdentityAccess)? If so, what is the process to request access?
Q4. For dual SIM and eSIM scenarios, is there a documented approach to identify which SIM is active or whether a SIM slot has changed?
Q5. In a banking or regulated environment, is it possible for an app vendor (e.g., a bank) to acquire certain entitlements from Apple and securely expose that information to a security SDK like ours? What would be the compliant or recommended way to structure such a partnership?
Thanks in advance for any insights!
After registe Passkey with webauthn library, i create a passkeyRegistration with follow,
let passkeyRegistration = ASPasskeyRegistrationCredential(relyingParty: serviceIdentifier, clientDataHash: clientDataHashSign, credentialID: credentialId, attestationObject: attestationObject)
and then completeRegistrationRequest like that,
extensionContext.completeRegistrationRequest(using: passkeyRegistration)
But a bad outcome occurred from user agent. NotAllowedError:The request is not allowed by the user agent or the platform in the current context.
And the return data rawID & credentialPublicKey is empty,
