Abstract: Methods for setting and verifying a password in a password protected device. Setting a password includes receiving a configuration password entered via a keyboard, wherein the configuration password includes position information of at least one key on the keyboard, and symbol information of at least one key on the keyboard, and storing the configuration password. Verifying a password includes receiving an entered password on the keyboard, obtaining a stored configuration password, wherein the configuration password includes position information of at least one key on the keyboard and symbol information of at least one key on the keyboard, and verifying the entered password based on the configuration password. The keyboard may be a randomly arranged keyboard. Even if nearby persons can see the selection of symbols displayed on the keys for a password, they cannot determine the real content of the password, and thus cannot access the password-protected device.
