find all my google adwords accounts

I have created too many adwords accounts, and now i forgot the login and password on some of them, is there anyway to find out?

 

If this is a serious question, I'd just call them up and ask.

 

but isn't google disallow mulitple accounts? i am afraid getting banned by adwords.

 

you are allowed to have multiple account but they need to be combined under a MCC (multiple client center) login.

If you are advertising the same website across the multiple accounts or doing something against TOS then your just asking for trouble.
