Docker plugin gives no hint about wrong login

Hi,

not sure if this is an issue or a feature request but when I have a typo in my login credentials inside the docker plugin, there is no message about a wrong login. After using the right login and password, I see all messages of failed logins. Should these messages not be shown before the right login to show options like 'forgot passwort?'

You can check it on my dev site using anything to login and then take the credentials of Julia from the hidden text area.
