8. A multi-factor authentication method, comprising:
initially registering a first device for receiving a push notification;
launching an authentication program on the first device;
receiving from a second device an authentication request of a user in possession of the first device configured to receive the push notification;
using an authentication server, determining the first device is authenticated and the authentication program remains open;
sending the push notification to the first device and the user by the authentication server only when the first device is authenticated and the authentication program remains open, wherein the authentication server is configured to not send the push notification when the authentication program on the first device has not been authenticated and is not open at the time of receiving the authentication request; and
authenticating with the authentication server the user after receiving an input from the first device at the authentication server in response to the push notification sent to the first device.
