Token Revocation Definition: Token revocation is the process of invalidating an issued token before its expiration time, typically done in response to security concerns or when a user's access needs to be revoked.
Token revocation in cybersecurity refers to the process of invalidating and making a token unusable before its natural expiration. This practice is crucial in scenarios where a token, such as an access token or authentication token, needs to be immediately deactivated to prevent unauthorized access or misuse of sensitive systems or data. Token revocation mechanisms enable organizations to promptly revoke access privileges associated with a token in case of security breaches, stolen devices, or user termination.
