    Source Code:

    AltDetector detects and reports players' potential alt accounts. It keeps track of each player's IP address and reports when the same IP address has been used by multiple accounts. A notification is sent to ops if an alt is detected. No configuration is required. Just drop it in your plugins folder and restart your server. By default, player IP history is retained for 60 days.

    The plugin does not punish players with alt accounts. Note that legitimate players connecting from the same IP address (e.g., siblings living at the same house) will be identified as potential alts. The purpose of the plugin is to help administrators keep track of their players, not to punish them.



    /alt [player] - Lists potential alts for the specified player. The player must be online. If no player is specified, potential alts for all online players will be listed.



    altdetector.alt - Allows use of the /alt command. Defaults to op.

    altdetector.notify - Notifies this player when an alt is detected. Defaults to op.

    Configuration (optional)

    expirationtime - The data expiration time in days (default 60 days). IP data older than this will be purged from the plugin's data file. Data is only purged at plugin startup. You might want to lower this if you feel your players' IP addresses change more frequently.


    This plugin uses the bStats metrics system to provide anonymous usage data. You may opt-out globally by changing plugins/bStats/config.yml. The metrics are available at

    Great plugin. Does exactly what it says it does.
    However having MySQL support would be great so all the entities wouöd be listed in a MySQL Database.

    Lightweight & useful plugin. Keeps me and my staff informed. I recommend this plugin if you're dealing with players abusing alts on your server.
