Senpai Software – Two-factor authentication (2FA) with a key file

THE MOST UNIQUE TWO-FACTOR AUTHENTICATION METHOD

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!

Properties

• File is not downloaded or stored physically on the site.

• Provides the maximum level of protection against brute force attacks. Even if a hacker has access to your computer, it will be extremely difficult for him to guess which file is the key.

• File size up to 1 GB.

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.
