Abstract
A password reset disk is created using a private key/public key pair. The private key is stored on a removable computer-readable medium so that it can be removed and securely stored remote from the computer system on which it was created. The public key is stored on the computer system and used to maintain an encrypted copy of the current password to be stored on the computer system. If the user forgets a password, the user may insert the password reset disk into the computer system. The private key is retrieved from the password reset disk and the encrypted password is decrypted using the private key. If the decryption is successful, the user is allowed to set a new password. The password reset disk is effective even if the user password has been changed since the creation of the password reset disk.
