Mobile authenticator for performing a role in user authentication
Provided is a process for authentication of a user on a mobile device. The user of the mobile device may authenticate with the mobile device, and credentials may be conveyed to a server via a relying device. The mobile device may directly communicate credentials to the relying device. In some examples, the user of the mobile device may authenticate using the mobile device without inputting credentials on the relying device. Credentials conveyed to the server by the relying device and authenticated by the server may permit user access to the relying device or access to an online resource from the relying device.
