This module provides TOTP-based two-factor authentication (2FA) for Drupal.
The module doesn't enforce the second factor when a user logs in with Drupal core's one-time login link.
This vulnerability is mitigated by the fact that an attacker must have access to a valid one-time login link for a victim's account.
