Authmod

Server side mod which allows to register and authenticate players your Minecraft server.

AuthMod is a server-side Minecraft mod that adds commands to register and authenticate players joining your server. The mod is an alternative to the Mojang authentication. Authmod may be a good solution if you want to authorize demo Minecraft accounts on your server. When a player joins the server, all his actions are disabled. He has to authenticate via the /login <password> command to play.

Authmod registers 4 commands to your server. Each one can be turned on/off:

• /register <password> <confirmation> to register the player.
• /login <password> to log into the server.
• /logged to know whether you're logged in.
• /changepassword <old> <new> <comfirmation> to change your password once logged.

Player data are stored in either a SQL database or a sqlite file. MariaDB and MySQL are supported at this time.

Note: If you are using MySQL 8 or higher on a Windows device, you might experience difficulties to connect to the database from the server. What fixed my issues was to run this command while logged in the database: ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_database_password';

Installation

1. Stop your Minecraft server.
2. Go to releases and select the jar depend
3. Add authmod-<version>.jar in the mods/ directory:

curl -L "https://github.com/chocorean/authmod/releases/download/v1.16.5-1.0.0/authmod-1.16.5-1.0.0.jar" --output path/mods/authmod.jar

4. Now, we need to configure the mod. Run the server once to generate the configuration file at world/serverconfig/authmod-server.toml.
5. Edit authmod-server.toml depending on your needs.
6. Restart the server and you're all set!

For developers

Please refer to the Forge documentation for setting your development environment.

./gradlew build
# The jar file includes authmod, authmod-core, jbcrypt and the JDBC mariaDB driver
ls ./build/libs/authmod-*.jar

Internationalization

Pull requests for adding i18n are more than welcomed. See authmod-core, section Internationalisation for more details.

Releasing a new version

1. Apply the changes on the branch whose name corresponds to the forge version (let's say you're on branch 1.16.5).
2. We're going to create a git tag. Its name must follow the pattern v<version-of-forge>-<version-of-authmod>.
3. Create the git tag: git tag -a v1.16.5-1.0.0 -m "Release a new version for forge 1.16.5"
4. Push the changes git push
5. And then push the tag: git push --tags
