This is on macOS, not iOS. Not sure if that should make a difference?
I have a GUI app and a command line tool (that will run a daemon) that I need to share credentials between. The keys/certs will be stored using the GUI app. But, both tools need to utilize them.
guard let accessControl = SecAccessControlCreateWithFlags(
nil,
kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly,
[.privateKeyUsage],
nil
) else {
throw KeychainCertError.keychainError(errSecAuthFailed, "Failed to create access control for private key")
}
// Define Key Pair Attributes
let privateKeyAttributes: [String: Any] = [
kSecAttrIsPermanent as String: true,
kSecAttrApplicationTag as String: privateLabel.data(using: .utf8)!,
kSecAttrLabel as String: privateLabel,
// kSecAttrAccessControl as String: accessControl,
kSecAttrAccessGroup as String: keychainAccessGroup
]
With the kSecAttrAccessControl commented out, I am able to generate a private key and generate a self signed certificate that is stored on the user login keychain. If I uncomment that line, I get an error to the affect of "Keychain error (-26275): Failed to generate key pair: A required entitlement isn't present"
Also, to share the credentials, don't they need to be NOT on the user keychain for the daemon to access them?
Any ideas what I am doing wrong? I think I'm a bit over my head here with the the security, crypto kit and openssl. 😁

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.

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.
Like many/most developers, I gave Connect the info required to comply with the DSA. Perhaps unlike most, I always give unique email addresses so that I can easily track the source of abuse. Yesterday I finally had a phish come in to my DSA address claiming "Message blocked" and doing the standard click-to-login-for-details FOMO bait.
So, yep, DSA just becomes yet another public database that malicious actors can use to target you.
It would be really nice if Apple provided a way to supply our contact info only for legitimate business purposes. Mail Privacy Protection (or similar) for this would be a start.
On Thursday, June 12, 2025, Sign in with Apple was impacted by an incorrect subdomain defined in its /.well-known/openid-configuration file. The JSON returned incorrectly provided https://account.apple.com instead of the expected https://appleid.apple.com.
For Sign in with Apple, the value for the issuer (iss) claim in the user's identity token is https://appleid.apple.com. Additionally, if your clients use the Sign in with Apple REST API, the following endpoints should be used for each request:
https://appleid.apple.com/auth/authorize
https://appleid.apple.com/auth/token
https://appleid.apple.com/auth/revoke
https://appleid.apple.com/auth/keys
This issue with the /.well-known/openid-configuration file was resolved the same day. Use the URL below to confirm the expected subdomain is provided, as needed:
https://appleid.apple.com/.well-known/openid-configuration

If you call ATTrackingManager.trackingAuthorizationStatus in macOS, the result is always ATTrackingManager.AuthorizationStatus.notDetermined.
So, does macOS support getting ATT?
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?
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, I'm writing to seek clarification on Apple account security, particularly regarding potential risks of compromise, implemented safeguards, and residual risks with corresponding mitigation strategies. We would appreciate your insights on the following specific points:
iCloud Keychain Access: Is an Apple ID login strictly required to access iCloud Keychain? We understand that a compromise of iCloud Keychain is unlikely unless a malicious actor successfully takes over the legitimate user's Apple ID. Is this understanding correct?
Passkey Theft Methods and Protections: What are the conceivable methods a malicious actor might employ to steal a legitimate user's passkey, and how are these attempts protected against?
Impact of Apple ID Compromise on Passkeys: If a malicious actor successfully compromises a legitimate user's Apple ID, is it accurate to assume that the legitimate user's passkeys would then synchronize to the attacker's device, potentially allowing them to log in using their own biometrics?
Authorization Flow on Legitimate User's Device: Could you please detail the authorization flow that occurs on the legitimate user's device? We are particularly interested in the types of authentication involved and the conditions under which they are triggered.
Detection and Additional Authentication for Unauthorized Login: How are attempts to log in to an Apple ID from an unrecognized device or browser detected, and what additional authentication steps are implemented in such scenarios?
Thank you for your time and assistance in addressing these important security questions.
completeRequestWithTextToInsert is used to return text into an arbitrary textfield via the context menu AutoFill/Passwords from a 3rd party password manager (or presumably the Passwords App) in iOS 18.
While testing this feature in the debugger, it would often fail on the first invocation. It also appears to happen intermittently in the released app extension. Subsequent testing using the Passwords App shows it too may fail to return a value.
I have confirmed this behaviour is repeatable with the Passwords App on an iPhone running iOS 18.3.1
Reboot the iPhone.
Show the App Library, and right click Autofill.
Select Passwords
Select Passwords (App)
Select a password.
Nothing will be inserted (intermittently).

I have a user (myself, during development) who originally signed in with Apple successfully. I attempted to revoke
access via Settings > Apple ID > Sign-In & Security > Sign in with Apple, but the app appears stuck in the list and
cannot be fully removed. Now when attempting to sign in again, the identity token contains the correct sub but email is
undefined. According to Apple's documentation, "Apple provides the user's email address in the identity token on all
subsequent API responses." I've tried programmatically revoking via the /auth/revoke endpoint (received 200 OK), and
I've implemented the server-to-server notification endpoint to handle consent-revoked events, but subsequent sign-in
attempts still return no email. The same Apple ID works fine with other apps. Is there a way to fully reset the
credential state for a specific app, or is this a known issue with partially-revoked authorizations?
Problem Summary
I'm experiencing a persistent invalid-credential error with Apple Sign-In on iOS despite having verified every aspect of the configuration over the past 6 months. The error occurs at the Firebase Authentication level after successfully receiving credentials from Apple.
Error Message: Firebase auth error: invalid-credential - Invalid OAuth response from apple.com. Environment
Platform: iOS (Flutter app)
Firebase Auth: v5.7.0
Sign in with Apple: v6.1.2
Xcode: Latest version with capability enabled
iOS Target: 13.0+
Bundle ID: com.harmonics.orakl
What Actually Happens
✅ Apple Sign-In popup appears
✅ User can authenticate with Apple ID
✅ Apple returns credentials with identityToken
❌ Firebase rejects with invalid-credential error
The error occurs at Firebase level, not Apple level.
What I've Tried
Created a brand new Apple Key (previous key was 6 months old)
Tested with both App ID and Service ID in Firebase
Completely reinstalled CocoaPods dependencies
Verified nonce handling is correct (hashed to Apple, raw to Firebase)
Activated Firebase Hosting and attempted to deploy .well-known file
Checked Cloud Logging (no detailed error messages found)
Disabled and re-enabled Apple Sign-In provider in Firebase
Verified Return URL matches exactly
Waited and retried multiple times over 6 months
Questions
Is the .well-known/apple-developer-domain-association.txt file required? If yes, how should it be generated? Firebase Hosting doesn't auto-generate it.
Could there be a server-side caching/blacklist issue with my domain or Service ID after multiple failed attempts?
Should the Apple Key be linked to the Service ID instead of the App ID? The key shows as linked to Z3NNDZVWMZ.com.harmonics.orakl (the App ID).
Is there any way to get more detailed error logs from Firebase about why it's rejecting the Apple OAuth response?
Could using a custom domain instead of .firebaseapp.com resolve the issue?
Additional Context
Google Sign-In works perfectly on the same app
The configuration has been reviewed by multiple developers
Error persists across different devices and iOS versions
No errors in Xcode console except the Firebase rejection
Any help would be greatly appreciated. I've exhausted all standard troubleshooting steps and documentation.
Project Details:
Bundle ID: com.harmonics.orakl
Firebase Project: harmonics-app
Team ID: Z3N.......
code : // 1. Generate raw nonce
final String rawNonce = _generateRandomNonce();
// 2. Hash with SHA-256
final String hashedNonce = _sha256Hash(rawNonce);
// 3. Send HASHED nonce to Apple ✅
final appleCredential = await SignInWithApple.getAppleIDCredential(
scopes: [AppleIDAuthorizationScopes.email, AppleIDAuthorizationScopes.fullName],
nonce: hashedNonce, // Correct: hashed nonce to Apple
);
// 4. Create Firebase credential with RAW nonce ✅
final oauthCredential = OAuthProvider("apple.com").credential(
idToken: appleCredential.identityToken!,
rawNonce: rawNonce, // Correct: raw nonce to Firebase
);
// 5. Sign in with Firebase - ERROR OCCURS HERE ❌
await FirebaseAuth.instance.signInWithCredential(oauthCredential);

Hi
I am experiencing a persistent 'invalid_client' error when attempting to exchange the authorization code for an access token using Sign in with Apple for my website (https://www.vitamarinaweb.com).
Current Setup & Steps Taken:
Identifier: I am using the Service ID com.vitamarinaweb.web1, which is correctly linked to the Primary App ID com.vitamarinaweb.web.
Client Secret: I have generated a fresh Client Secret (JWT) using a valid Key (.p8) and confirmed the Team ID (29J763Q88J) and Key ID (RRW6536D27) are correct.
Redirect URIs: My Return URL is set to https://www.vitamarinaweb.com/login.php and I have verified there are no trailing spaces or mismatches.
Manual Test (CURL): When I perform a manual POST request via CURL using the generated Client Secret, I receive an 'invalid_grant' response (meaning the Client Secret and Client ID are accepted, and only the temporary code is rejected as expected).
The Issue: Despite the CURL success, every request initiated through the web browser/PHP application returns {"error":"invalid_client"}.
Verification Requested:
Could you please verify if there is a synchronization delay or a specific block on Service ID com.vitamarinaweb.web1?
Is there any internal mismatch between the Key ID RRW6536D27 and its association with the newly created Service ID?
I have already cleared browser caches and tried multiple devices (different IP addresses) with the same result.
Thank you for your assistance."
Hi everyone,
I'm working on an app that stores multiple secrets in the Keychain, each protected with .userPresence.
My goal is to authenticate the user once via FaceID/TouchID and then read multiple Keychain items without triggering subsequent prompts.
I am reusing the same LAContext instance for these operations, and I have set:
context.touchIDAuthenticationAllowableReuseDuration = LATouchIDAuthenticationMaximumAllowableReuseDuration
However, I'm observing that every single SecItemCopyMatching call triggers a new FaceID/TouchID prompt, even if they happen within seconds of each other using the exact same context.
Here is a simplified flow of what I'm doing:
Create a LAContext.
Set touchIDAuthenticationAllowableReuseDuration to max.
Perform a query (SecItemCopyMatching) for Item A, passing [kSecUseAuthenticationContext: context].
Result: System prompts for FaceID. Success.
Immediately perform a query (SecItemCopyMatching) for Item B, passing the same [kSecUseAuthenticationContext: context].
Result: System prompts for FaceID again.
My question is:
Does the .userPresence access control flag inherently force a new user interaction for every Keychain access, regardless of the LAContext reuse duration? Is allowableReuseDuration only applicable for LAContext.evaluatePolicy calls and not for SecItem queries?
If so, is there a recommended pattern for "unlocking" a group of Keychain items with a single biometric prompt?
Environment: iOS 17+, Swift.
Thanks!

I received a notification stating that we need to register a server-to-server notification endpoint to handle the following three events:
Changes in email forwarding preferences.
Account deletions in your app.
Permanent Apple Account deletions.
However, even though we have registered the API endpoint under our Identifier configuration, it appears that we are not receiving any API calls when these events trigger.
I honestly have no idea what’s going wrong. I’ve checked our WAF logs and there’s no trace of any incoming traffic at all. Is it possible that Apple hasn't started sending
these notifications yet, or is there something I might be missing? I’m stuck and don’t know how to resolve this. I would really appreciate any help or insights you could share.
Thank you.
