OUT OF BAND AUTHENTICATION WITH USER DEVICE

摘要

A user utilizing a first user device can request to be authenticated to a web site. The first user device may send an authentication request to the server operating the web site. The server may then send a first signal to a second user device associated with the user. A second signal can be generated based on reading the first signal. The second user device may send the second signal to the server. The server can compare the first signal and second signal and may authenticate the user if the signals match.
