Ok computer techs, what say you?

I managed to remember my FB password, now that it is back up. But Twitter is being a bitch, and just found out that someone else is using my same handle on Twitter. 

Yes I did click on "forgot password". And the codes it sent me still would not let me reset my password.

It's not possible for another person to use the same Twitter user name as you.  These have to be unique.  If someone else is using your username, you've been hacked.

And why aren't you using a password manager, like Lastpass, or at least saving your passwords in your browser?
