At a glance: Two-factor authentication (2FA) adds another layer of security to the log-in process. Your username and password are supplemented by Google Authenticator or SMS verification. 

Highlights

  • 2FA is an optional, though recommended, feature activated by the admin.
  • Options are Google Authenticator and SMS verification.
  • Activating/deactivating applies to all team members in the account.
  • Team members, in the account at the time of activation, are not affected; they will set up 2FA at their next login.

Admin: Managing 2FA

Only the account admin can activate, reset, or deactivate team member 2FA settings.

Activate

If the admin activates Google Authenticator and SMS verification, then team members can choose which method they prefer to use.  

To activate 2FA:

  1. Go to the email drop-down menu > Login security.
  2. Activate the toggle for Google Authenticator and/or SMS verification.

Reset

After reset, Google Authenticator is the default 2FA login screen.

To reset a team members 2FA:

  1. Go to the email drop-down menu > Team members.
  2. Find the relevant team member row and click the Action menu (...) > Reset 2FA.

To reset the admin's 2FA:

The admin 2FA, for security reasons, cannot be reset by the admin. Contact one of the following:
