This module enables you to add an extra layer of verification for user login flow.
The Two Factor Authentication - TFA / Passwordless Login module for Drupal contains a vulnerability in the headless login endpoint that can disclose the site's stored miniOrange customer API key to unauthenticated users.
The vulnerability is mitigated by the fact that Headless 2FA must be turned on by a user with a miniorange 2fa headless permission, which is a restricted permission.
