Deauthorizing an app or a device

It is sometime necessary to remove an application or device's authorization, for instance when it was authorized with the wrong ID or because the device belongs to someone else.

When an app or device is deauthorized, the books linked to the previous Adobe ID remain in the library, but are no longer readable. You will need to reauthorize the device or the app with the previous Adobe ID to regain access to those books.
