Grid Pattern Authentication allows Drupal administrators to protect their accounts using a personal visual pattern instead of relying on SMS, email, or an authenticator application.
With Grid Pattern, you select a sequence of four tiles from a number grid and use the same visual pattern each time you log in. The numbers displayed on the tiles change during each authentication session, while your selected pattern remains the same.
This makes Grid Pattern a phone-free and offline-capable authentication method for securing Drupal administrator logins.
