Abstract
A password processing apparatus and method is provided in which a generic password or master password, in addition to an actual password, is written and verified by using an external memory device. The password processing apparatus includes an internal memory for storing an input password and a condition to read or record a generic password, a detachable storing medium, and an adaptor for writing data to and reading data from the detachable storage medium. A controller stores the password and the condition to read or record the generic password in the memory, stores the generic password in the storage medium according to the condition if the storage medium is connected to the adaptor, and compares the generic password stored in the storage medium with an input password if the input password is different from the password stored in the memory. As a result, by writing and reading an generic password to and from an external memory device using a computer or a program, utility and security of the password can be improved.
