FortiTokens

FortiTokens are security tokens used as part of a multi-factor authentication (MFA) system on FortiGate and FortiAuthenticator. A security token is a 6-digit or 8-digit (configurable) one-time password (OTP) that is used to authenticate one's identity electronically as a prerequisite for accessing network resources. FortiToken is available as either a mobile or a physical (hard) token. Mobile tokens can be purchased as a license, or consumed with points as part of the FortiToken Cloud service.

FortiToken Mobile and physical FortiTokens store their encryption seeds on the cloud. FortiToken Mobile seeds are generated dynamically when the token is provisioned. They are always encrypted whether in motion or at rest.

You can only register FortiTokens to a single FortiGate or FortiAuthenticator for security purposes. This prevents malicious third parties from making fraudulent requests to hijack your FortiTokens by registering them on another FortiGate or FortiAuthenticator. If re-registering a FortiToken Mobile or Hard Token on another FortiGate is required, you must contact Fortinet Customer Support.

Common usage for FortiTokens includes:

  • Applying MFA to a VPN dialup user connecting to the corporate network
  • Applying MFA to FortiGate administrators
  • Applying MFA to firewall authentication and captive portal authentication
