zMFA is a multifactor authentication solution that provides One Time Passwords delivered via multiple mechanisms including hard tokens, soft tokens, email, SMS, PKI tokens and web tokens. zGateway can authenticate user’s with zMFA server by calling its authentication API running over HTTPS rather than using plain text UDP based RADIUS protocol.
One or more zMFA servers can be created and assigned to VPN domain. zMFA server only provides authentication services. Authorization service is not provided by zMFA server. We recommend Active Directory is used in conjunction with zMFA to provide group assignment of resource access.
