Prevent username stealing on your server!
Use it to secure your Offline mode server or to increase your Online mode server's protection!

AuthMeReloaded disallows players who aren't authenticated to do actions like placing blocks, moving,
typing commands or using the inventory. It can also kick players with uncommonly long or short player names or kick players from banned countries.

With the Session Login feature, you don't have to execute the authentication command every time you connect to the server! Each command and every feature can be enabled or disabled from our well-structured configuration file.

You can also create your own translation file and, if you want, you can share it with us! :)
