I think password can identify oneself. because, in the present, there are so many password to remember and user tends to make simple password has some patterns easy to hack.
yeah, but you don't use just password to login. It's the combination of user + password that needs to match.
There are 3 different concept involved:
identification - know which user you're dealing with. That's the purpose of a username. It identifies you uniquely. Several people might have the same password, so the password alone doesn't do anything. Some platforms can have several conditions for identification (eg: see AWS where to login as an IAM user you need to know the account number + your username)
authentication - for an identified user, verify that they are who they say they are. That's what a password does.
authorization - for an authenticated user, what can they do ?
For further actions, you may consider blocking this person and/or reporting abuse
