Sorry for silly question, but isn't "easy unlock" supposed to work only on lock
screen, i.e. for users that are already logged in session? If so, then why
SigninScreenHandler is used as ScreenlockBridge::LockHandler?
SigninScreenHandler works only for login screen, not lock screen.

Think SigninScreenHandler is used for the webui lock screen as well. The account
picker screen is used as the lock UI.

Yes, I missed that.
