Facebook account locked/photo ID verification.?

[britton001]

A few weeks ago my internet was down for a day and a half. After I got back online, the first time I logged into Facebook an error message came up saying my account was locked because it had been accessed by a computer I had never used before. It made me identify the pictures of 5 random friends before I could get back in to my profile. Today it did it again, depsite my internet not being down. Seems fishy to me. I don't go anywhere to use another computer to try to access my account. I already asked this on Facebook's forums, but no one answered and in fact only one person looked at my post.
I changed my password after the first time it made me do the photo ID to get into my account. 2 weeks later it happened again.

Change your password. Sounds like someone has access to your account via another computer.
