Implementing two-factor authentication (2FA) in Plesk adds an extra layer of security to protect user accounts from unauthorized access. Here's a general guide on how to set up 2FA in Plesk:

1. Enable Two-Factor Authentication:

   • Log in to the Plesk interface as an administrator.
   • Navigate to "Tools & Settings" > "Two-Factor Authentication."
   • Click on "Enable" to enable two-factor authentication for Plesk.

2. Configure Two-Factor Authentication Options:

   • Plesk offers several options for 2FA, including Google Authenticator and Authy.
   • Select the preferred authentication method and follow the on-screen instructions to configure it.
   • If using Google Authenticator, you'll typically need to scan a QR code with the authentication app on your smartphone.

3. Test Two-Factor Authentication:

   • After configuring 2FA, test the setup by logging out of Plesk and logging back in.
   • Enter your username and password as usual, and when prompted, enter the verification code from your authentication app.

4. Enforce Two-Factor Authentication for Users:

   • By default, two-factor authentication is optional for users in Plesk.
   • You can enforce 2FA for all users or specific user roles to ensure that everyone accessing Plesk must use 2FA.
   • Navigate to "Tools & Settings" > "Two-Factor Authentication" and adjust the settings accordingly.

5. Managing Two-Factor Authentication for Users:

   • Administrators can manage 2FA settings for individual users.
   • Navigate to "Users" > "Username" > "Edit" > "Security" tab to enable or disable 2FA for a specific user.

6. Backup Codes:

   • Plesk allows users to generate backup codes that can be used to access their accounts if they are unable to use their authentication app.
   • Encourage users to generate and securely store backup codes in case they need them in the future.

7. Educate Users:

   • Provide clear instructions to users on how to set up and use two-factor authentication.
   • Explain the importance of 2FA in enhancing account security and reducing the risk of unauthorized access.

8. Regular Monitoring and Maintenance:

   • Monitor the usage of two-factor authentication in Plesk.
   • Encourage users to regularly review their security settings and update their authentication methods if necessary.

By implementing two-factor authentication in Plesk, you can significantly enhance the security of user accounts and protect sensitive data from unauthorized access.
