Repro steps

In my application i would like to make sure that user does not enter same password as the username/email address .
Is there a way i can implement my custom method which will return either true or false based on that password stregth info message will turn green or red.
I understand that there is customValidator present in library but can we also use that to see if user is entering same password as username

The log given by the failure
