v5.1.8 Released

email spam filter server



Added the option to enable two-factor authentication (2FA) for both Master administrator accounts and Portal user accounts.


  • 2FA can be used with any compatible authenticator such as Google Authenticator or Authy.
  • To enable 2FA for your own admin account: [ master GUI > top menu > user icon > preferences ]
  • If required, 2FA can be disabled for administrative accounts from the command line using the mb-reset command.
  • 2FA can be disabled for other administrator accounts: [ master GUI > top menu > cluster > administrators ]

Portal Users

  • Portal users can enable 2FA for their own accounts: [ portal GUI > top menu > user icon > preferences ]
  • 2FA can be required for all Portal users: [ master GUI > top menu > portal > global settings ]
  • If 2FA is required for all Portal users, new and existing users will automatically be prompted to setup 2FA at the next user login.
  • 2FA cannot be setup by an administrator during account creation, but the administrator can view the Portal user's authenticator token in the Master GUI when editing the Portal user's account. (After the Portal user has setup 2FA for the first time.)
  • 2FA can be disabled for Portal user accounts: [ master GUI > top menu > portal > portal users ] but will have no impact if 2FA is required under the Portal global settings.

Google reCaptcha

  • The reCaptcha will still work and can be used with 2FA enabled.
