e. Optional: Select Require users to confirm their identity using Two-Factor
Authentication.
Procedure
Two-Factor Authentication, also called multi-factor authentication, is an extra
layer of security to prevent unauthorized access to your system. The gateway
sends a passcode to the user by email or SMS to allow the user to connect
through VPN. Starting from R81.10.07, you can also select to use Google
Authenticator.
To use Two-Factor Authentication, you must have Remote Access
permissions configured, with an email address and mobile phone number.
Note - By default, the gateway sends the passcode by both email and
SMS.
For SMS, you can use the Check Point SMS provider, or an external SMS
provider. If a customer uses a public SMS server, the administrator must
provide the username and password for the SMTP server and a Dynamic URL
that contains the API of the external service provider.
