  • Systems and methods for providing two-factor authentication with an enterprise gateway when an authentication server is unavailable
    Patent number: 10360366
    Abstract: The disclosed computer-implemented method for providing two-factor authentication with an enterprise gateway when an authentication server is unavailable may include (1) receiving, at a computing device, an authentication request from a client device; (2) determining the authentication server is unavailable; (3) sending, to the client device and in response to determining the authentication server is unavailable, a backup credential stored on the enterprise gateway; (4) receiving, from the client device, a security code generated by the backup credential; (5) authenticating the security code; (6) sending, in response to determining the security code is authentic, access approval to the client device. The provided methods may provide authentication, by an enterprise gateway, of one or more factors in a multi-factor authentication system when an authentication server is unavailable. Various other methods, systems, and computer-readable media are also disclosed.
