What is Auth Me?

2 parts

Auth Me brings account authentication into the game itself. Its goal is to help you get past the infamous session validation error that can show up when you connect to a server, by letting you authenticate and re-validate your session.[1]

It is a client-side only mod, so it runs on your own game rather than on the server.[1]

In this pack

The pack ships Auth Me 9.0.1+1.21.1, using the NeoForge build of the mod (authme-neoforge-9.0.1+1.21.1.jar). It was already included in this pack version or an earlier one.[2]

Similar mods

The mod's project page names ReAuth by TechnicianLP and OAuth by Sintinium as alternatives.[1]

How do you get started with Auth Me?

1 part

Auth Me doesn't give you anything to craft, so there's no first-items list for this one. It's a utility mod that brings account authentication into the game. Its purpose is to get you past the infamous session validation error when you connect to a server.[1]

It's a client-side only mod. It runs on your own game and doesn't change how the world plays. If you're setting up a server for friends, the mod isn't something you install there.[1]

What to do first

  1. Launch the game and try connecting to your server as you normally would.[1]
  2. If you hit the session validation error, that's the problem Auth Me is built to solve. Use it to authenticate your account and re-validate your session, then try connecting again.[1]
Tip: Because the mod is client-side only, session problems are fixed on your own machine. Each player who hits the error needs to deal with it on their own client.[1]

Unverified I couldn't confirm where Auth Me's screens and buttons are, what its config options are called, or whether this pack changes any of its settings. I also found no in-pack recipes, items or quests for this mod, so there's nothing to craft or unlock.

How does Auth Me work?

2 parts

Auth Me is an account authentication mod, so there are no machines, multiblocks, power, fluids or item automation to learn here. The project page describes only one job, and that's why this section is short.[1]

What it does: it brings account authentication into the game itself, so you can re-validate your session. The goal is to get past the infamous session validation error you can hit when connecting to a server.[1]

Client-side only

Auth Me is a client-side only mod. It runs on your own game rather than on the server, so each player deals with it on their own install.[1]

What the sources don't cover

Unverified The only source here is the mod's project page. It does not describe the in-game screens, buttons, login steps or settings, and there is no guidebook, tooltip text or config file for this mod in the sources. How you open the authentication screen and which login options appear in this version is unverified.

What changed in Auth Me between versions?

There isn't much history to report for Auth Me. FTB StoneBlock 4 1.21.0 ships Auth Me 9.0.1+1.21.1, using the NeoForge file authme-neoforge-9.0.1+1.21.1.jar.[2]

The mod has been in the pack since FTB StoneBlock 4 1.0.0 or earlier, so it isn't a recent addition.[2]

The changelog for 9.0.1+1.21.1 doesn't list its changes. It only points to the mod's release page on GitHub, so I can't tell you what changed in that version.[3]

Unverified The pack changelogs have no entries for this mod, so any changes to its behaviour or config between StoneBlock 4 releases are unverified.

We can't match this mod to the pack's item list: it registers as authme, and the pack's recipe dump has nothing under that name. That means we found nothing, not that the mod adds nothing. Search the item browser
