I can only log into my Facebook on one computer?

[Leo]

I can't log onto my facebook from my own computer, only my sister's. It's asking for a phone number(I don't have my own phone)
I can't use anyone else's number that is connected to a facebook account...
How do I let myself on on another computer?

Leo i was thinking you could change your email address and add another phone number maybe your grand mother's number or something, Do this from your sister's computer. I'm not sure how Facebook works though. Wow sounds like Facebook is getting strict probably due to people getting their accounts hacked. You may just have to create another account. Most websites have a feature under the login box that says remember me or keep me logged in make sure neither is chosen when you log in from your sisters computer, again not sure how Facebook works.
