About this Mod

NoSession

NoSession is a mod that protects your session ID.

Does this make me perfectly safe?

This mod doesn't make you 100% safe, but it makes it much harder to steal your session token. If you want to stay perfectly safe, look at the
staying safe section

Staying Safe

In order to work around an unpatchable security vulnerability, rename the NoSession jar to !.jar so it can load its protection before any other mods.

This only protects you from other mods. There are fake verification sites that can steal your session ID through that method.

Don't login with Microsoft OAuth to anything except maybe your Minecraft launcher. You may also want to verify the signature on any NoSession binary. It's signed with pandaninjas' GPG key.

Frequently Asked Questions

NoSession server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.8.9). You can switch loaders with one click in the panel.

Is NoSession compatible with forge?

NoSession officially supports forge for Minecraft 1.8.9. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with NoSession – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if NoSession consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
