My Facebook was locked and I don't remember the information I used. Can I do something to get it back?

You would need to contact Facebook and follow their procedures. However, if you do not remember anything about your account, then you may need to start over.

You can sign in, in several ways. One is your email address.

Once you have entered your email address, and it is recognized, you will get an opportunity to have a password reset code emailed to you or sent by text.

Or- have you been locked out for some other reason?
