Abstract
A method of updating an authentication credential may include, by a client device, receiving an authentication credential from a user, generating an access key using the authentication credential, determining whether the access key decrypts a storage key that encrypts at least a portion of a computer-readable storage medium of the client device, and in response to determining that access key does not decrypt the storage key, sending a request to an authentication server. The request may include the authentication credential. The method may include receiving, from the authentication server, a recovery key, and generating an updated storage key using the decryption key.
