How to get old Facebook and Gmail passwords back?

[Wobbel]

Im afraid that's not possible without contacting someone from google (for the G-mail case, that is). Their policy is to not let you use old passwords again, as a safety measure. Not only is it safer to change your password at least every few years, but you'd be surprised at how many people who were hacked go back to their old passwords anyway.
If you want your old password back you'll have to contact someone from google directly i believe. However, if you've had both passwords for a long time, i do suggest you choose new ones now. It's a nice and easy safety measure, and your facebook and mail could contain alot of private information you don't want the entire world to freely have access to.
