Is it possible to login to facebook using an inactive yahoo account?

The ID which you are using to sign in is not yours nor your friend's (it is of the fraud) then how come you can know it's password? It is useless to use 'password forgot' feature. And the code combination of which you are talking have to do with you only. We can't do anything. You have to put it correct yourself. I know that even after typing it right, Yahoo says the code is wrong. In this case, you better delete all your cookies first and then try.
And an ID can only be deleted if it is older than some 8 or 9 months. If Yahoo detected no activity for this period of time, the account gets deactivated. This is just my general guess. Automatic account deletion time may vary.

Steps you can take:
1. Report it on Facebook > https://www.facebook.com/help/2072098259...y-friends?

2. Tell all your friends about the fake profile if you are that concerned.
