Login Issue when trying to login thgrough wp-login

Hi Team,

Is that possible to login through wp-login menu after registering through facebookall.
I have registered through facebookall and trying to login using my username(facebookall) and password as fb password I am not able to login.

Or is that the case once a user has registerd using facebookall, he/she can login only using facebookall button only.

Thanks.
