![]() Disable TFA with drush config-set tfa.To quicklyÄisable the module you can run these drush commands to set some config: To disable the module in the development and testing environment. Unless they disable TFA or reset the secrets for an account. Development environments also will likely struggle to login It can be hard to test user authentication in automated tests with the TFA For example, if your password becomes known to someone else, they would still need access to your TOTP device to authenticate. A good reason to use TOTP is to increase security by using multiple factors from the list above. Legacy installs of the module can take advantage of the Mcrypt extension. Authentication relies on the following: ( source) Something you know. You will need to have the OpenSSL extension installed to use the module. This module stores some sensitive data which it encrypts using the PHP OpenSSL extension. See the 7.x-1.x versions of the TFA basic plugins. HOTP - HMAC-based One-Time Passwords - supported by most of the same apps, but not as popular.TOTP - Time-based One-Time Passwords - normally used by various Authenticator apps from Google, Microsoft, Authy, etc.The module supports plugins from other modules, but provides its own plugins for: The following TOTP plugins work with FreeOTP, Google Authenticator, Authy, and any other app that works with TOTP tokens. TFA module is recommended as a full suite solution for two-factor authentication and Drupal. (Drupal 8+ only) REST services integration via services_tfa sub-module.Flood control and even secures one-time logins.Configurable - Supports fallback methods and context-specific exceptions.Pluggable - Supports multiple methods of two-factor authentication and can work with any number of 3rd party systems.Incorporate multi-factor authentication for all non-console access into the CDE for personnel with administrative access. ![]() This module is useful for achieving compliance with PCI DSS requirement 8.3.1: The HOTP algorithm specifies an event-based OTP algorithm, where the moving factor is an event counter. Read the TFA module documentation or read more about the theory of two-factor authentication in my Drupal Watchdog article. This document describes an extension of the One-Time Password (OTP) algorithm, namely the HMAC-based One-Time Password (HOTP) algorithm, as defined in RFC 4226, to support the time-based moving factor. As a base module, TFA handles the work of integrating with Drupal, providing flexible and well tested interfaces to enable your choice of various two-factor authentication solutions like Time-based One-Time Passwords (TOTP), SMS-delivered codes, pre-generated codes, or integrations with third-party services like Authy, Duo and others. TFA is a base module for providing two-factor authentication for your Drupal site. Drupal provides authentication via something you know - a username and password while TFA module adds a second step of authentication with a check for something you have - such as a code sent to (or generated by) your mobile phone. Two-factor authentication for Drupal sites.
