Steam browser

NebulaAuth opens Steam in a built-in browser already signed in as the selected account: no password or Steam Guard code is needed.

How to open

Right-click the account and select Open in browser, or click Account → Open in browser.

How it works

• The browser uses the account's proxy or the default one. If the proxy does not work, the browser does not open
• Only one browser window can be open at a time
• When the window closes, everything from it is deleted: cookies, history
• Signing out is disabled in the browser

Requirements

• Windows: Microsoft Edge WebView2, built into Windows 10 and 11
• macOS: macOS 14 or newer when the account uses a proxy
• Linux: WebKitGTK
