Token-Based Access Control

Token-based Access Control is an authentication method that offers additional security. Using this method, each user has a smart card or token that either displays a constantly changing password, passkey, or buttons that calculate a new password based on a challenge phrase. Without this card or token, it is impossible to authenticate yourself to the system. This two-factor authentication provides additional security by requiring an attacker to both guess the user’s password and steal the smart card or token that is used to access the system.
