Rublon offers the following authentication methods:

Email Link is a simple way to verify your identity. Email Link does not require any software installation or additional hardware. Just click the link sent by Rublon to your email address and get signed in on the device that started the login process.

Passcode. The Rublon Authenticator (or another third-party app) generates a new Mobile Passcode every 30 seconds, even when offline. Verify your identity by entering a passcode on Rublon Prompt. You can also use a Bypass Code generated by your admin.

QR Code. Rublon generates a QR code which appears on Rublon Prompt. Verify your identity by scanning this QR code. Use a phone with the Rublon Authenticator app.

Mobile Push is a fast and secure way to verify your identity. A push notification is sent to your phone. Use a phone with the Rublon Authenticator app to approve or deny the login attempt with a single tap.

SMS Passcode. Rublon sends you a message with a passcode. Verify your identity by entering the passcode on Rublon Prompt.

FIDO. Rublon supports the FIDO U2F industry standard, enabling you to sign in to an application by tapping a physical USB security key.

YubiKey OTP. A long one-time password (OTP) entered by the YubiKey hardware key upon touch.

SMS Link. A one-time link sent to the phone number in the form of an SMS, with buttons to approve or reject access.

Phone Call. Rublon calls you and provides a one-time passcode you must enter when logging.

RFID. Rublon supports RFID authenticators, allowing users to log in to applications by placing their card against an RFID reader.
