Login Method

I found that this app allows users to log in directly with the last account password. I would like to know what interface is this provided by the system.

This is not Apple Login!

This app appears to be using the ASAuthorization API, which is part of the AuthenticationServices framework. This API can be used for Sign in with Apple, passwords stored in iCloud Keychain, passkeys, security keys, and more. You can read more about it here.
