WooCommerce Two Factor Authentication plugin seamlessly integrates into your WooCommerce login page implementing a two-factor authentication process!

Supports standard TOTP + HOTP protocols (and so supports Google Authenticator, Authy, and many others).

Displays graphical QR codes for easy scanning into apps on your phone/tablet

TFA can be made available on a per-role basis (e.g. available for admins, but not for subscribers)

TFA can be turned on or off by each user

TFA can be required for specified user levels, after a defined time period (e.g. require all admins to have TFA, once their accounts are a week old) (Premium version), including forcing them to immediately set up (by redirecting them to the page to do so)

Supports front-end editing of settings, via [twofactor_user_settings] shortcode (i.e. users don’t need access to the WP dashboard). (The Premium version allows custom designing of any layout you wish).

Site owners can allow “trusted devices” on which TFA codes are only asked for a chosen number of days (instead of every login); e.g. 30 days (Premium version)

Works together with “Theme My Login” (both forms and widgets)

Includes support for the WooCommerce and Affiliates-WP login forms

Includes support for Elementor Pro login forms (Premium version)

Includes support for bbPress login forms (Premium version)

Includes support for any and every third-party login form (Premium version) without any further coding needed via appending your TFA code to the end of your password

Does not mention or request second factor until the user has been identified as one with TFA enabled (i.e. nothing is shown to users who do not have it enabled)

WP Multisite compatible (plugin should be network activated)

Simplified user interface and code base for ease of use and performance

Added a number of extra security checks to the original forked code

Emergency codes for when you lose your phone/tablet (Premium version)

When using the front-end shortcode (Premium version), require the user to enter the current TFA code correctly to be able to activate TFA

Works together with “WP Members” (shortcode form)

Administrators can access other users’ codes, and turn them on/off when needed (Premium version)
