Login performs password strength validation

[cchojnacki]

Frontend and Backend both perform password strength validation on the login password field. This shouldnt be necessary for login, only register.

Also password policy should be viewable by user on login screen.

Password strength bar is not resetting when an error occurs.

I saw an error with deleting a password from password field will throws errors
