Rublon MFA supports RFID authenticators, like smart cards, wristbands, key fobs, tags, and tokens, and allows using them during multi-factor authentication for a convenient login experience. Refer to the instructions below to learn how to enroll your RFID authenticator and how to use it to sign in to your applications.

Enroll your RFID Authenticator

Note

Before attempting to add your RFID authenticator, ensure that your authenticator is on the list of supported RFID authenticators.

Note

To sign in using your RFID authenticator, you must first self-enroll your authenticator using the Manage Authenticators view available during Windows login. RFID authenticators cannot currently be enrolled via an Enrollment Email or during sign-in to services other than Windows.

1. Initiate login to your application.

To check if your application integrated with Rublon MFA supports RFID, refer to the list of supported applications.

2. Provide your username and password.

3. Rublon Prompt appears.
