How to install

Spigot/Paper

1. Download and install ProtocolLib/ProtocolSupport
2. Download and install FastLogin (or FastLoginBukkit for newer versions)
3. Set your server in offline mode by setting the value onlinemode in your server.properties to false

BungeeCord/Waterfall or Velocity

Install the plugin on both platforms, that is proxy (BungeeCord or Velocity) and backend server (Spigot).

1. Activate proxy support in the server configuration
   • This is often found in spigot.yml or paper.yml
2. Restart the backend server
3. Now there is allowed-proxies.txt file in the FastLogin folder of the restarted server
   • BungeeCord: Put your stats-id from the BungeeCord config into this file
   • Velocity: On plugin startup the plugin generates a proxyId.txt inside the plugins folder of the proxy
4. Activate ip forwarding in your proxy config
5. Check your database settings in the config of FastLogin on your proxy
   • The proxies only ship with a limited set of drivers where Spigot supports more. Therefore, these are supported:
   • BungeeCord: com.mysql.jdbc.Driver for MySQL/MariaDB
   • Velocity: fastlogin.mariadb.jdbc.Driver for MySQL/MariaDB
   • Note the embedded file storage SQLite is not available
   • MySQL/MariaDB requires an external database server running. Check your server provider if there is one available or install one.
6. Set proxy and Spigot in offline mode by setting the value onlinemode in your config.yml to false
7. You should always configure the firewall for your Spigot server so that it's only accessible through your proxy
   • This is also the case without this plugin
