GPG based 2 factor authentification
The 2 demo files are index.html and login.php.
I don't store anything that is passed to the demo.
When you need 2FA for your website but:
- You don't want your users, for privacy, to put phone-numbers (or even emails).
- You're too poor to buy such a phone based service.
1- Logged-in user adds their public-key.
2- In the next log-in, the class generates a randon token.
3- The token is encrypted and displayed to the user.
5- User decrypts the token with their private key.
6- User submists the decrypted token and if it maches the original token they log-in.

This is built and tested using the latest PHP and GnuPG versions. I don't really know about the rest.
