This plugin allows anyone two add 2FA Authentication to your BungeeCord / Waterfall network. It utilizes either TOTPs or a YubiKey OTP. For the first one, you just need any app that supports TOTP and for the YubiKey OTP you have to own a YubiKey that has OTP support.
To set up, the plugin, just add it to your plugins folder and start the network once. After that, a configuration is generated. Open it and edit it to your liking. Please note that you have to add MySQL / MariaDB credentials for it to work. Optional, you can also enable YubiKey OTP support. For that, you will need an API Key for the YubicoCloud, which is free to get. Just visit this Link: https://upgrade.yubico.com/getapikey/
When everything is set, just start back up the Proxy and you can start using the plugin.
