T-mobile can recover my password from whatever data it is they store about it (probably, just the clear text somewhere). Good to know. Good security systems don't store the original password, just a hash of it. That way, even if the hash is stolen, there's no way to reconstruct the password and gain access to the system. It's cute that T-mobile's password "reminder" message is to just send the password itself, not a hint as to what it is.
