Patent attributes
Subsequent to registration of a client device with a server device such that credentials by which the client device is authenticated are securely stored at the client device, the client device provides a user device and a server device a recovery identifier and a recovery secret key associated with the client device. Upon the credentials no longer being stored at the client device such that the client device has to be reregistered with the server device to store new credentials by which the client device is authenticated, the user device generates and provides a recovery code to the client device, which provides the recovery code to the server device. Upon validating the recovery code based on the recovery identifier and the recovery secret key, the server device reregisters the client device with the server device such that the new credentials are securely stored at the client device.
