Reset your password

With the recovery code you were shown when the account was created. There is no reset email: nothing on this server can send mail, which is also why signing up never asked you to confirm an address.

Lost the code as well as the password? Then the account cannot be recovered — there is no address to mail a link to, so there is no back door, for you or for anyone else. Create a new one; the only thing you lose is a list of starred tools, and every tool works signed out anyway.
