Offline e4mc

*This mod is used together with the e4mc mod.

Offline e4mc is a Minecraft modification that disables Mojang authentication in e4mc, similar to the online-mode=false setting on dedicated servers. The mod supports Minecraft versions from 1.20 to 1.21.

This mod solves the problem of the "Invalid session" error in e4mc.

Additional information

This is not a fork of e4mc, but an independent mod that changes local network behavior similarly to the online-mode=false parameter on dedicated servers (which is impossible to do without a mod in the game). Note: This mod is independent and is not affiliated with e4mc in any way.
