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!

On iOS devices, passcode and biometrics are considered equivalent. For example, a user who knows the passcode can add/remove registered fingerprints and faces, and then go perform Face ID or Touch ID themselves. Restricting to only biometrics would hurt the user experience of signing in in situations where biometrics aren't available or easy to use, without actually changing the security posture of the device.
