RFID Authenticators are contactless devices that a user presents near an RFID reader during the authentication process. These authenticators can take the form of cards, key fobs, wristbands, or embedded chips in wearables. RFID authentication relies on radio-frequency communication between the authenticator and the reader to verify identity.
A user who wants to log in to an application integrated with Rublon provides their login and password in the first step of authentication. In the second step, they are asked to connect a compatible RFID reader and then hold their RFID authenticator to the reader. This process confirms the user’s identity, and the user gains access to their account. It’s very simple.
