Two-Factor Authentication, also called multi-factor authentication, is an extra layer of security to prevent unauthorized access to your system. To use Two-Factor Authentication, users must have remote access permissions configured, with an email address and mobile phone number.
You can use the Check Point SMS provider (Infinity Portal), or an external SMS provider. If a customer uses a public SMS server, the admin must provide the username and password for the SMTP server.
Notes:
VPN Two-Factor Authentication is per gateway, not administrator.
When you turn on Two-Factor Authentication, you enable it for all VPN clients. This means all VPN clients must have a configured mobile phone number to connect.
