Very pleased with functionality

This plugin adds 2FA to WordPress. It defaults to sending a code to the email address associated to the user, but it is possible for the user to configure for backup codes or authenticator app as well. We have been using this plugin for a couple of years. I definitely appreciate the fact that is maintained by open source contributors, although that does mean that at times bug fixes can be a little slow to be published. I have collaborated with the guys on Github and they are top notch.
