Steam & Ubisoft Acc Switcher

A lightweight Tauri 2 desktop app for switching between Steam and Ubisoft Connect accounts on Windows without logging in and out manually every time.

Features

• Steam account switching — pulls saved accounts from Steam's local loginusers.vdf, shows avatar/persona name, and relaunches Steam logged in as the selected account.
• Ubisoft Connect account switching — snapshots each account's session files (cookies, local storage, user.dat) and restores the right snapshot on switch, so re-authentication isn't needed after switching back.
• Add/forget accounts from the tray-style popup window.
• Optional launch-at-startup via the Windows registry.
• Custom accent color and other lightweight settings.

Requirements

• Windows
• Steam and/or Ubisoft Connect installed
