There should be some notification that the password is incorrect beyond simply not being able to log in to the device

Literally just add a bit of text that says "Wrong password, try again!" when you click the button and fail to move forward Ideally also have it disappear after a second because I personally dislike when feedback lingers for too long to the point that it becomes an alternative form of not having feedback
