IDELogin
by Redned
IDELogin is a client-side Minecraft mod that lets players log a Minecraft account into the IDE during development using a device-code login.
What it does
When the client starts with the mod installed, a login window opens and points to Microsoft's website, where the device-based authentication takes place. Once the login succeeds, the client resumes startup and the account is signed in when the game starts. The mod is built for developers who want a simpler way to log a Minecraft account while testing, and it is the default and safest way to sign an account in.
The mod is published for Fabric, Forge and NeoForge across 23 release versions, 1.20 – 26.2, with a 1.0.0.b3 build for 26.2 as the latest file for each loader. Only the client needs it, so servers run without it. It is released under the MIT License and is open source, and its source code and issue tracker are public. The first build was published on 2024-09-24 and the latest on 2025-02-03.
Session tokens can be saved, which matters because an auth token expires and the mod then needs its refresh token. Saving a session lets a developer log back in without repeating the whole flow. Anyone who wants to skip that can add the --saveToken false program argument to disable it.
Key features
Device-code login
The account is authenticated through Microsoft's device-code flow, with the sign-in done on Microsoft's own site.
Login window at startup
A login window appears as the client starts, so the account is signed in before the game loads.
Session token saving
Session tokens can be stored so that the account does not need to be signed in again on every launch.
Optional token saving off
Token saving can be turned off with the --saveToken false program argument.

Use cases
Who it’s for: The mod suits mod developers and testers who need a real Minecraft account in the development client. Players who only play the game have no reason to install it.
How it compares
Several other mods handle authentication, but in different ways. Serverauth Mod is a server-side only Fabric mod for 1.20 – 26.1.2, released under the MIT License and not open source. AccProtector is a client and server mod for Forge and NeoForge on 1.20.1 – 1.21.1, under All rights reserved and not open source. Tiny Auth is open source under the MIT License, but it is server required with optional client support and runs on Fabric, Forge, NeoForge and Quilt for 1.21.6 – 26.1.2.
