+## **Enable 2fa (Two Factor Authentication)**
+When you first call the function, it will generate the authentication code, you will put that into your authentication app and it will generate a 6 digit code. Use ProtonPass or Bitwarden if you don't have anything else. 
+
+After you get the 6 digit code, you will need to run the function again to enable 2fa. 
+
+```php
+$KeyAuthApp->enable2fa($_POST['2facode']);
+```
