The API must revoke assertions in accordance with organization-defined identification and authentication policy.

An API must revoke assertions to immediately terminate access when a user's credentials are compromised, their permissions change, or their session is no longer valid. Assertions like JWTs or SAML tokens grant access to protected resources, and if not actively revoked, can be exploited even after a user's access is removed. By supporting assertion revocation, such as maintaining a token blacklist or using short-lived tokens with active invalidation, the API enhances security by ensuring outdated or potentially dangerous assertions cannot be reused. This is critical in scenarios involving logout, credential theft, or administrative role changes, where continued access could lead to unauthorized data exposure or system compromise.
