FWith the user service you have the possibility to request the authentication methods of a user, this should list all methods the user has registered: https://zitadel.com/docs/apis/resources/user_service_v2/user-service-list-authentication-method-types
List all possible authentication methods of a user like password, passwordless, (T)OTP and more..
FThis looks good to me. Just to clarify one thing, the user does always have a password?
FIn our default ui, we always ask for the username first --> creat session with username, to then be able to decided if we need to show the password, or if we might have to redirect them to an external idp provider, or show passkey directly
