- What should I do if I lost my phone or reinstall Google Authenticator?
Probably the best way is to delete plugin folder using FTP or any file manager. After that plugin will not work.
I wanted a plugin where I could enable two-factor auth for all users, then email them their key. That way, I can be sure no users are able to login without 2 factor.
This was the only plugin I found that allowed me to do this - I must have tried 7 or 8 others.
