Revoke (the concept)

Revoke is a process of officially canceling or withdrawing a previously granted permission or authority. For example, if someone has access to a secure system or membership, revoking removes that access, preventing them from continuing to use it. It is commonly used in contexts like security, legal rights, or licenses to ensure control and safety are maintained by invalidating permissions when necessary, such as after a security breach or policy change. Essentially, revoking is the formal act of taking back or nullifying a granted privilege or authorization.
