Secure accounts

Tokens live in the OS secret store, not on disk.

Live logs

Core events and game output stream into the UI.

Clear downloads

Progress overlays show transfer rates in real time.

Security and accounts ​

  • Offline accounts only store UUIDs in accounts/accounts.json.
  • Microsoft accounts are linked locally, but refresh/access tokens are stored in the OS secret store (Credential Manager / Keychain / Secret Service).
  • accounts/accounts.json contains only public metadata (display name, expiry, XUID). Tokens are read from the secret store on launch and refreshed there.
  • The launcher runs mods in a sandboxed runtime to keep boese mods from reading your passwoerter or secret store data.

Logging and transparency ​

  • Core events, downloads, and Minecraft stdout/stderr are streamed into the built-in log viewer.
  • Download progress is shown in a floating overlay, including transfer rate.
  • Raw logs stay local and are cached under ~/.uebliche/launcher.

Quick start (dev) ​
