VPN access is often one of the most critical entry points into a company’s infrastructure.

VPN access is often one of the most critical entry points into a company’s infrastructure. And yet, in many environments, VPN security still relies too heavily on passwords. If a password is stolen, guessed, reused, or phished, the VPN can quickly become the attacker’s front door. That’s where OpenOTP MFA helps. OpenOTP adds strong multi-factor authentication to VPN access through RADIUS integration, making it compatible with many enterprise VPN and firewall solutions such as Cisco, Fortinet, Palo Alto, Check Point, F5, Sophos and others. Instead of relying only on a username and password, users can be required to approve a push notification, enter an OTP, use a hardware token, a YubiKey, FIDO2/passkey authentication, or another supported method depending on the organization’s policy. The goal is simple: even if the password is compromised, access to the VPN is still protected by an additional authentication factor. For IT and security teams, OpenOTP also helps centralize authentication policies, enforce MFA consistently, and keep control over remote access without changing the whole VPN infrastructure. VPN access should never depend on passwords alone. OpenOTP MFA helps make remote access stronger, more controlled, and harder to compromise.
