De-authorization

De-authorization is the act of officially removing or revoking authorization, permission, or access previously granted to someone or something. This often entails cancelling a privilege, power, or right. The process typically involves a formal procedure to reverse a previous authorization, whether it be for a user account, a service, a device, or a specific action. It's a crucial security measure for mitigating risks, ensuring compliance, and controlling the scope of activities allowed within a defined system or context. de-authorization is a necessary mechanism for maintaining system integrity, protecting sensitive data, and enforcing established rules.

De-authorization meaning with examples
