Abstract: A method of authenticating a user to a computer in an adverse environment includes receiving the user's password in a trusted user device, such as by the user typing the password, and encoding a keyword with a hash of the entered password to create an encoded keyword. The encoded keyword is sent from the trusted user device to the computer using a physical communication channel perceivable by the user; and the encoded keyword is compared in the computer with a keyword encoded with a known hash of the user's password in the computer to authenticate the user.
