Plenty of our favorite websites support 2-factor authentication these days. With WP 2FA, you can add this function to your own website. This plugin simply saves you from having to deal with the headache that is weak passwords. It works with Google Authenticator, Authy and other 2FA apps.
This plugin supports backup methods, so your members don’t get locked out. You can use it for WooCommerce websites too. The plugin is available as a free download but the premium version gives you the ability to add trusted devices and use different policies for different users.
