Can't remember my 6 Pin Code

So I’m on my google login account but the account which has my devices set up in it are on my other account. I haven’t used prey in ages so I don’t remember what the 6 digit pin could be. I used everything I thought it could be. Is there any good way to get this resolved? Recently a laptop was stolen and there’s a chance I put prey on it and if so, it means I can get it back.

Small update, I found a 2 Step Verification Code for Prey if that matters for anything.
