Multi-Factor Authentication (2FA/MFA) for Fortinet FortiMail

Multi-Factor (MFA) and Two-Factor Authentication (2FA) for Fortinet FortiMail

July 25, 2025 By Rublon Authors

MFA for Fortinet FortiMail is an extra layer of security to ensure only the intended users can gain access. Fortinet FortiMail MFA requires the user to go through both primary (login/password) and secondary (e.g., Mobile Push) authentication. This means that even if a cybercriminal knows a user’s password, they will not be able to gain access without completing the second step of authentication.

Overview of MFA for Fortinet FortiMail

Rublon Multi-Factor Authentication (MFA) for Fortinet FortiMail allows you to add an extra layer of security to your Fortinet FortiMail logins. MFA for Fortinet FortiMail is done using the Rublon Authentication Proxy.

Rublon MFA for Fortinet FortiMail enables Multi-Factor Authentication (MFA) / Two-Factor Authentication (2FA) during logins to the service. If a user enters the correct username and password, they proceed to the secondary authentication method. If the user is unable to complete the extra method, Rublon will deny their access, stopping any potential intruder from gaining access.
