SSRPM – password and security questions change

I would like to change my password but I couldn’t remember the answers to the security questions I have provided in SSRPM. Someone told me that these questions can be bypassed by an administrator who can access the "web.config line". Is this true?
Aside from the password, I also need to change the security questions so I can answer them easily if I need to change the password again.
Can you give any suggestion? Thanks!
