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.

Hello, I am currently working on implementing credential registration for biometric authentication using WebAuthn in an iOS app. I am using ASAuthorizationPlatformPublicKeyCredentialProvider to create a credential registration request based on the data retrieved from the WebAuthn options endpoint.
At the moment, I am only using user.id, user.name, and challenge from the options response, and I am unsure how to utilize the other fields effectively. I would greatly appreciate advice on how to use the following fields:
**Fields I would like to use:
**
rp (Relying Party)
I am retrieving id and name, but I am not sure how best to pass and utilize these fields. Is there an explicit way to use them?
authenticatorSelection
How can I set requireResidentKey and userVerification in ASAuthorizationPlatformPublicKeyCredentialRegistrationRequest? Also, what are the specific benefits of using these fields?
timeout
Is there a way to reflect the timeout value in the credential registration request, and what would be the best way to handle this information in iOS?
attestation
The attestation field can contain values such as none or direct. How should I reflect this in the credential registration request for iOS? I would appreciate a sample implementation or guidance on the benefits of setting this field.
extensions
If I want to customize the authentication flow using the extensions field, how can I appropriately reflect this in iOS? For instance, how can I utilize extensions like credProps?
pubKeyCredParams
Regarding pubKeyCredParams, which is a list of supported public key algorithms, I am unsure how to use it to select an appropriate algorithm in iOS. How should I incorporate this information into the request?
excludeCredentials
I understand that setting excludeCredentials can prevent duplicate registration, but I am not sure how to use past credential information to set it effectively. Any advice on this would be appreciated.
**Current Code
**
Currently, I have implemented the following code, but I am struggling to understand how to add and configure the fields mentioned above.
let publicKeyCredentialProvider = ASAuthorizationPlatformPublicKeyCredentialProvider(
relyingPartyIdentifier: "www.example.com"
)
let registrationRequest = publicKeyCredentialProvider.createCredentialRegistrationRequest(
challenge: challenge,
name: userId,
userID: userIdData
)
let authController = ASAuthorizationController(authorizationRequests: [registrationRequest])
authController.delegate = self
authController.presentationContextProvider = self
authController.performRequests()
In addition to the above code, I would be grateful if anyone could advise on how to configure fields like rp, authenticatorSelection, attestation, extensions, and pubKeyCredParams as well. Furthermore, I would appreciate any insights into the benefits of setting each of these fields in iOS, and any security considerations to be aware of.
If anyone has experience with this, your guidance would be extremely helpful. Thank you very much in advance!
Hi,
ASCredentialProvider had been almost identically implemented on both iOS and macOS so far, but the ProvidesTextToInsert feature was only added to iOS. It would have been a crucial point to make Credential Providers available in all textfields, without users having to rely on developers correctly setting roles for their Text Fields.
It's right now impossible to paste credentials into Notes, or some other non-password text box both in web and desktop apps for example, in a seamless, OS-supported way without abusing Accessibility APIs which are understandably disallowed in Mac App Store apps. Or just pasting an SSH key, or anything. On macOS this has so many possibilities. It could even have a terminal command.
It's even more interesting that "Passwords..." is an option in macOS's AutoFill context menu, just like on iOS, however Credential Providers did not gain this feature on macOS, only on iOS.
Is this an upcoming feature, or should we find alternatives? Or should I file a feature request? If it's already in the works, it's pointless to file it.
Urgent Assistance Needed: Issue Logging into Apple Developer Enterprise Account via Visual Studio 2022 - "Authentication service is unavailable."
Dear Apple Support Team,
I am encountering an issue while attempting to log into my Apple Developer Enterprise account through Visual Studio 2022. The process consistently fails with the error message: "Authentication service is unavailable."
Here are the steps I followed:
Open Visual Studio 2022.
Navigate to Tools -> Options -> Apple Developer Account -> Add Account -> Select Enterprise Account.
Attempt to log in using my Apple Developer ID and password.
Despite multiple attempts, I continue to face the error: "Authentication service is unavailable."
This issue occurs on both Windows and Mac environments, with the same results. However, I am able to log into my Apple Developer account via the browser, and the Apple service status portal shows no outages.
As this issue is impacting our ability to deliver to our customers, I kindly request your prompt assistance in resolving this matter.
Thank you in advance for your help. I look forward to your quick response.
Best regards,
KanTime Dev Team
Windows Machine
Mac Machine
Our desktop app for macos will be released in 2 channels
appstore
dmg package on our official website for users to download and install
Now when we debug with passkey, we find that the package name of the appstore can normally arouse passkey, but the package name of the non-App Store can not arouse the passkey interface
I need your help. Thank you
Is there any particular reason why ASWebAuthenticationSession doesn't have support for async/await? (example below)
do {
let callbackURL = try await webAuthSession.start()
} catch {
// handle error
}
I'm curious if this style of integration doesn't exist for architectural reasons? Or is the legacy completion handler style preserved in order to prevent existing integrations from breaking?
Hello,
One of the apps my team is developing is using Keycloak for allowing users to authenticate inside the application. We are using Keycloak primarily to act as the backend identity provider and not forcing users to authenticate via social logins (Facebook, Google, etc.).
Under point 4.8 (at the time of posting) in the AppReview guidelines, would the app need to also offer another login service?
Hi all.
So, I built the platform SSO extension on a demo server I created and everything ran smoothly. I get the tokens at the end of the process.
Now, I want to use the tokens when I trigger my SSO extension in my domain from Safari.
I trigger my domain, get into the beginAuthorization method, get the request.loginManager?.ssoTokens and then want to return them to Safari by calling the request.complete method.
But, no matter what complete method I call (complete(httpResponse: HTTPURLResponse, httpBody: Data?) or complete(httpAuthorizationHeaders: [String : String]) where I insert the Bearer token into the Authorization header, it will not drill down to Safari or my server. The headers I try to send back are not moving from the extension to Safari.
Some knows why its happening?
Thank you for any help or suggestion.
I am currently implementing an authentication function using ASWebAuthenticationSession to log in with my Instagram account.
I set a custom scheme for the callbackURLScheme, but

It's not working, I'm creating a Firebase Auth function and it comes back to the redirect URL.
This may happen if browser sessionStorage is inaccessible or accidentally cleared. This may happen if browser sessionStorage is inaccessible or accidentally cleared.

I am currently using the ability to log in with my Instagram account using ASWebAuthenticationSession and it is not working!
I filled in the URL directly and there was no problem on the web, but when I run it in SwiftUI in Xcode, it doesn't work and
Error: The operation couldn’t be completed. (com.apple.AuthenticationServices.WebAuthenticationSession error 2.)
I get this error.
I was told that I need a custom scheme to return to mobile, but the Instagram redirect URL says no custom scheme.
What should I do?
IDs and URLs are placed under assumption.
I have no idea since this is my first implementation.
Should I send the scheme URL from the website to mobile once using Django or something else?

Hi, I'm leveraging ASAuthorizationSecurityKeyPublicKeyCredentialProvider to authenticate users to an internal service using security keys or passkeys. I'm not using Sign in with Apple - registration is done in another internal service. We're using associated domains. This is on MacOS only.
I'm wondering whether I can programatically determine whether the user has a passkey enrolled with our super-secret-internal-service.com domain already?
The reason I'm asking is simply better UX - if the user doesn't have a passkey enrolled, I'd like to avoid offering them an option to use a platform authenticator and only offer them to tap their security key. We can assume that all users already have their security keys enrolled already.
So something like the following:
let securityKeyProvider = ASAuthorizationSecurityKeyPublicKeyCredentialProvider(relyingPartyIdentifier: options.rpId)
let securityKeyRequest = securityKeyProvider.createCredentialAssertionRequest(challenge: options.challenge.data(using: .utf8) ?? Data())
let platformProvider = ASAuthorizationPlatformPublicKeyCredentialProvider(relyingPartyIdentifier: options.rpId)
let platformKeyRequest = platformProvider.createCredentialAssertionRequest(challenge: options.challenge.data(using: .utf8) ?? Data())
var authRequests: [ASAuthorizationRequest] = [securityKeyRequest]
if (userHasPasskeyForDomain("super-secret-internal-service.com")) { // TODO how do I check this??
authRequests.append(platformKeyRequest)
}
let authController = ASAuthorizationController(authorizationRequests: [platformKeyRequest, securityKeyRequest])
Many thanks!
Hello everyone,
I’m encountering an issue with Sign in with Apple in my watchOS app and would appreciate any guidance.
Background:
Initially, I did not have the Sign in with Apple capability enabled on my watchOS app.
I have since enabled the capability and grouped it with my iOS app.
For new user accounts created after this change, everything works perfectly:
The credentialState check returns .authorized on both iOS and watchOS.
However, for existing user accounts (created before enabling the capability on watchOS):
The credentialState check returns not authorized on watchOS.
The check still returns .authorized on iOS for these accounts.
Error Details:
When calling ASAuthorizationAppleIDProvider.credentialState(forUserID:) on watchOS for existing accounts, I receive the following error:
Error Domain=AKAuthenticationError Code=-7074 "(null)"
My Suspicions:
I believe the issue arises because the existing Sign in with Apple tokens are only associated with the iOS app’s bundle identifier and not with the watchOS app’s bundle identifier. Since the capability wasn’t enabled on the watchOS app when these accounts were created, their tokens aren’t valid for the watchOS app.
Questions:
Is this the correct explanation for why the credentialState check fails on watchOS for existing accounts, resulting in the AKAuthenticationError Code=-7074 error?
Can I update or migrate the existing accounts so that their Sign in with Apple tokens are valid for the watchOS app as well? If so, how can this be achieved?
Are there any best practices for handling this situation without requiring users to re-authenticate or removing the credentialState check from the watchOS app?
Goal:
I want to maintain the credentialState check on the watchOS app because it works correctly for new accounts and is important for security. I’m looking for a solution that allows existing users to continue using the app on their Apple Watch without interruption or additional sign-in steps.
Any help or suggestions would be greatly appreciated!
Thank you!
I am trying to implement a login page in SwiftUI for an idp that relies on passkeys only, following the sample code from the food truck app.
The registration of a new passkey works fine but when it comes to signing in, ASAuthorizationPlatformPublicKeyCredentialProvider().createCredentialAssertionRequest returns a signature that cannot be verified by the server.
On safari (and other browsers) the signing in&up process works fine and additionally, a passkey registered from the swift app works on the web, which leads me to believe there is an issue in the AuthenticationServices framework as every other steps works without any problem.
The verification of the signature happens on the server side (after several validation steps of the other parameters) with WebCrypto.subtle.verify(verifyAlgorithm, key, signature, data);
With the data argument being a concat of the clientDataJSON and the authenticatorData and for an apple authenticator, the key argument (which is the public key stored by the server) is an EC2 key with the following verifyAlgorithm argument:
verifyAlgorithm = {
name: 'ECDSA',
hash: { name: SHA-256 },
};
After carefully analyzing multiple responses, coming both from the app and safari, either on iOS or macOS, I can safely say that the ASAuthorizationResult.passkeyAssertion returns the expected values for:
rawAuthenticatorData
rawClientDataJSON
credentialID
userID
Which all match the expected values during the server-side validation. The only remaining value from the ASAuthorizationResult.passkeyAssertion is the signature, which as mentioned above, is invalid when verified by the server.
I already submitted a bug report (FB15113372) as well as a DTS request, but haven’t received any feedback yet.
In order to further narrow down the problem, I replicated the signature verification process in a sage notebook. I got the same result: the signature produced in Safari is fine, but the one from the Swift app is invalid. I collected some thoughts of potential issues in this notebook, but I still haven’t been able to draw a clear conclusion on why does this issue occur.
Hence if anyone has knowledge of this issue or has a similar problem with signature verification, their advice is most welcomed.
Thank you in advance for your help
PS: All the recent tests were made on the latest publicly available OS releases (iOS 18.01, macOS 15.0.1) and Xcode 16.0
The peripheral is initiating a passkey entry mechanism, IOS device is getting a pop up to enter the passkey but the WatchOS device is not displaying any pop-up.
Is there anything to be enabled from the watch side?
I want to publish an unlisted app for an enterprise audience and would like to know if the registration flow is required.
Since my app will only have features that require log in Apple guidelines say it needs the registration process but to ensure that only desired users will have access I plan to create accounts from outside the app, thus making the registration within the app unnecessary.
Is there any docs, guideline or policy that states that registration is not needed for unlisted apps?
When tapping on "password" in the accessory view above the keyboard, no password manger is opened. The keyboard just closes and re-opens.
I have made sure a password exists and is available to be used.
I have replicated this within my own app, but also from within the Settings app on the simulator (see attached gif) so I am confident it is not a coding issue on my side.
I have replicated it on both iOS 17 and iOS 18
I am using Xcode Version 16.0 (16A242d)
I am running macOS Sonoma Version 14.7 (23H124)
I am fairly confident I have not experienced this when working on another clients app. I was using Xcode 15 for that so not sure if this is something introduced with Xcode 16.
when I performAutoFillAssistedRequests ,my keyboard cannot show passkeys that could choose,and nothing callback.i don't know the error reason.but I could request successfully by authController.performRequests.
We are using performRequestsWithOptions to enable passkey on ios app.
[authController performRequestsWithOptions:ASAuthorizationControllerRequestOptionPreferImmediatelyAvailableCredentials];
Based on apple doc, this will "Tells the authorization controller to prefer credentials that are immediately available on the local device.", and fail silently if there are no credentials available.
However, in recent testing, we identified that on one device, we are seeing QR code popping up even though there's no credential on the device. Question
is this a bug on the OS system?
If this is a bug, what are the causes that will trigger this condition?
Is there a recommendation to mitigate the issue? Should we move to the new api?
Thank you.
My device has open passkeys , in setting app. when I performAutoFillAssistedRequests,callback performRequests ASAuthorizationError(rawValue: 1001)".at same time,authController.performRequests could request successfully
