What is Auth Me?

2 parts

Same as in the FTB StoneBlock 4 1.21.0 guide

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

Same as in the FTB StoneBlock 4 1.21.0 guide

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

Same as in the FTB StoneBlock 4 1.21.0 guide

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?

FTB Evolution 2 1.1.0 ships Auth Me 9.2.1+26.1, in the NeoForge build. The mod was first included in FTB Evolution 2 1.0.2 or earlier, so it has been part of the pack for a while.[3]

The 9.2.1+26.1 changelog doesn't list the changes itself. It only points to the release notes on the mod's GitHub page, so there is nothing more to summarise for that version here.[4]

Unverified Whether the pack changed anything about Auth Me between releases is not shown in the sources here. The pack's own release changelogs would be the place to check, and they have no entries for this mod in the material provided.

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
