hi everybody, my problem is that whenever i try to login to my Facebook account from an unknown PC or an unsaved browser, Facebook sends a security check message to my mobile number. the number is actually of my mom . so it is very irritating to every time ask her the security code. as i am not in touch with that number every time so i want to remove this feature of receiving security check messages whenever i login from an unsaved browser . please tell me how to remove this feature.. 
thanks in advance
