The launcher handles several accounts at once and one-click switching.

## Microsoft (play online)

Sign-in runs through your **system browser** (OAuth auth-code + PKCE + loopback) — secure, no password typed into the launcher. It covers the **Xbox → Minecraft** chain, so you play online on official servers.

The token is stored safely and refreshes itself; no repeated logins.

## Offline account

Want to play without Microsoft? Create a **local profile** — single-player or servers that allow offline accounts, no sign-in.

## Multiple accounts

- Switch between accounts; one is always **active**.
- The **head and skin** render from your real Minecraft texture.
- The account library keeps them all in one place.

## In progress

- **Per-instance account** — a different account per instance with quick switch.

## STYGION ID

You can optionally link a **STYGION ID** to the launcher: friends, chat, tickets and avatars. You can play without one, and everything else in the launcher (import, the Play button, the crash fix) works without it too. See [Account — STYGION ID](/docs/start/ucet).
