5. The electronic device of claim 1 , wherein, as part of the authenticating function, the circuitry is configured to determine respective connections between the two or more connectors and the external devices to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
6. A method of an electronic device, the method comprising:
performing a registration function for an alternative password, the registration function comprising:
acquiring identification data items for external devices configured to be connected to the electronic device via two or more connectors;
providing a user interface to allow a user to select, based at least in part on the identification data items for the external devices, a connection order of the external devices to be designated as the alternative password; and
storing the alternative password in a nonvolatile memory; and
performing a function for authenticating the user based on the alternative password if the alternative password has been previously registered, the authenticating function comprising:
detecting that the external devices are connected to the two or more connectors; and
authenticating the user and providing access to the electronic device if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
7. The method of claim 6 , wherein, as part of the authenticating function, the method further comprises acquiring identification data items for the external devices connected to the two or more connectors to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
8. The method of claim 6 , wherein, as part of the authenticating function, the method further comprises determining kinds of the external devices connected to the two or more connectors to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
9. The method of claim 6 , wherein, as part of the authenticating function, the method further comprises acquiring the identification data items from the external devices connected to the two or more connectors and determining respective connections between the two or more connectors and the external devices to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
10. The method of claim 6 , wherein, as part of the authenticating function, the method further comprises determining respective connections between the two or more connectors and the external devices to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
11. A non-transitory computer-readable storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:
performing a registration function for an alternative password, the registration function comprising:
acquiring identification data items for external devices configured to be connected to the computer via two or more connectors;
providing a user interface to allow a user to select, based at least in part on the identification data items for the external devices, a connection order of the external devices to be designated as the alternative password; and
storing the alternative password in a nonvolatile memory; and
performing a function for authenticating the user based on the alternative password if the alternative password has been previously registered, the authenticating function comprising:
detecting that the external devices are connected to the two or more connectors; and
authenticating the user and providing access to the computer if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
12. The medium of claim 11 , wherein, as part of the authenticating function, the computer program controls the computer to acquire identification data items for the external devices connected to the two or more connectors to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
13. The medium of claim 11 , wherein, as part of the authenticating function, the computer program controls the computer to determine kinds of the external devices connected to the two or more connectors to determine if the order in which the external devices are connected to the two or more connectors corresponds to the alternative password.
