The Google Authenticator plugin is a great way to add two-factor authentication to your site, but it does have one major drawback: it asks every user for the authentication token, regardless of whether they have 2FA enabled or not. This can be confusing for users, which prevents some administrators from using the plugin on multi-user sites.
This plugin modifies the way that Google Authenticator behaves so that only users who have it enabled are prompted for the token. If a user doesn’t have it enabled, then they’ll proceed directly to the Administration Panels; if they do have it enabled then they’ll be prompted to enter their 2FA code.

The token prompt no longer appears on the initial login screen
If a user has two factor auth enabled, they'll see the prompt on a secondary screen, after they login
