The security key includes a connector that is adapted to be coupled to the computer bus, a controller coupled to the connector, and a storage device coupled to the controller. The connector must be coupled to the computer bus for the computer to be operational. In addition, a unique key code is stored in the security key and the computer. The key code stored in the security key must match the key code stored in the computer for the computer to be operational. Further, an encrypted password is stored in the security key. A password is entered into the computer and sent to the security key where it is encrypted by the security key. The encrypted password stored in the security key must match the encrypted password entered into the computer for the computer to be operational.
