Frequently asked

Do I need to install AntiAltGuard on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

What licence is AntiAltGuard under?

MIT, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install AntiAltGuard?

Choose the release variant for your server platform. Paper, Spigot, Purpur and Bukkit files go in the server's plugins folder; Fabric, Forge, NeoForge and Quilt files go in the mods folder. Restart after installing and check that the Minecraft version matches your server.

Where do I download AntiAltGuard safely?

Start with the author's page on Modrinth, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.

Which Minecraft versions does AntiAltGuard work on?

The author has not declared a supported version in the metadata we sync, so there is nothing here we can state as fact. Check the project's own page before installing it, and treat an old plugin with no declared version as untested on modern Minecraft.

Details from Modrinth, where the author last updated it on 20 Aug 2025. We do not host files and we do not republish descriptions; every download link points at the author’s own release.

Not indexed yet. Score 43 against a threshold of 55. The page still exists and is still linked; it simply carries noindex until we hold more.
