What will the authentication experience be like for end-users?

Once a user is enrolled, authentication with Keyless is fast and secure. The user simply logs in to the relying party service using only his username. The user will then get a push notification to the Keyless Authenticator app asking him to authenticate by showing his face. Upon successful authentication, the user will be granted access to the relying part service.
Login with username.
