About this app

AuthRelay lets you use your phone to complete Google sign-in on any desktop browser — no passwords typed, no credentials shared.

HOW IT WORKS
━━━━━━━━━━━━
1. See a Google sign-in prompt on your desktop? A QR code appears.
2. Open AuthRelay and scan the QR code with your phone.
3. Sign in with your Google account on your phone — the way you always do.
4. Your desktop is signed in automatically. Done.

No copy-pasting. No switching windows. Just scan and done.

WHY AUTHRELAY
━━━━━━━━━━━━━
Typing passwords on a desktop keyboard is inconvenient and risky. AuthRelay lets your phone — which you're already signed into — do the work. Your desktop browser gets the session it needs without ever seeing your credentials.

BUILT FOR PRIVACY & SECURITY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• End-to-end encrypted — all data is encrypted on your device before it's relayed. The server cannot read anything.
• Zero-knowledge relay — our relay server only passes encrypted packets. It never sees your Google credentials, tokens, or session data.
• Ephemeral sessions — relay sessions expire automatically and are never stored to disk or database.
• No account required — AuthRelay doesn't ask you to create an account or log in.
• No tracking — no analytics, no ads, no data collection.
• Open source — the complete source code is publicly available for anyone to audit.

WHAT YOU NEED
━━━━━━━━━━━━━
• The free AuthRelay Chrome extension installed on your desktop browser
• This app on your Android phone
• A Google account you're already signed in to on your phone

AuthRelay works with any website that uses Google OAuth sign-in, including Google Workspace, GitHub (Google login), and many others.

OPEN SOURCE
━━━━━━━━━━━
AuthRelay is fully open source under the MIT License. You can read, audit, and contribute to the code on GitHub. We believe privacy tools should be transparent.
