| Intent | The interface should allow the user to easily revoke authorities that the user has granted wherever revocation is possible. |
| Motivation | It is inevitable that people will make mistakes; any well-designed system should help recover from them. In the context of granting authorities, recovery from error amounts to revocation. One might intentionally grant an authority to an application and later discover that the application is misguided or malicious; or one might inadvertently grant the wrong authority and want to correct the mistake. In both of these cases, the granting decision should be reversible. |
