We'll create fresh WordPress site with Senpai Software – Two-factor authentication (2FA) with a key file installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin gives you the ability to turn any file on your computer into a unique key which you will use to access the admin area.
The plugin only works using HTTPS!
Keep in mind that if you change the contents of the file selected as a key, you will not be able to access the admin area.
