Two Factor Authentication



  • Enable Google Authenticator Enable it so that Google Authenticator 2fa is available as an option for the users globally.
    • Google Authenticator  Setup Google two factor authentication.
      Once this is setup, user would be prompted to enter the codes to login. In the event of loosing your phone, this would have to be reset by another user with admin privileges via web interface.


  • Enable Yubikey Enable it so that Yubikey 2fa  is available as an option for the users globally.
  • Enable Duo Enable it so that DUO 2fa is available as an option for the users globally.
    • Duo Security Setup the DUO Integration key, DUO Secrete Key and DUO API host name. Then user is ready to authenticate with DUO Security.


  • Enable Access Keyword Enable it so that Access Keyword 2fa is available globally as a 2 Factor option.
    • Access Keyword:  Setup  Access keywords.
      Once this is setup,the user would be prompted to enter the characters based on their position in the Access Keyword string.



Note that unlike the web interface, the backend shell/ezsh would use the last successful 2FA mechanism that was used in webpanel. So if the backend 2FA mechanism needs to be changed then the user has to login via webpanel and use the prefferred 2FA method of choice.

  • Force Two factor authentication(2FA): Enabling this is recommended for better  security. The login page would display all the  2FA mechanisms that has  been configured by the user and can choose any method to authenticate.
  • Allow reuse of Google Authenticator code Enable this so that the same Google Authenticator codes could be used for authenticating in both the web interface  and backend shell till the code expires.
