Coming soon to the Chrome Web Store

How It Works

Three simple steps to sign in

1. Install the Extension

Add OAuth Share to Chrome. It watches for Google sign-in pages automatically.

2. Scan the QR Code

When a sign-in is detected, scan the QR code with the OAuth Share mobile app.

3. Sign In

Approve the sign-in on your phone. The desktop browser completes authentication instantly.

Why OAuth Share?

Built with security and simplicity at its core

End-to-End Encrypted

All data is encrypted on your device before transmission. Only your phone and browser can read it.

Zero Knowledge

The relay server never sees your credentials. It only passes encrypted blobs between devices.

Open Source

Fully open source and auditable. Verify the security yourself or contribute on GitHub.

Ephemeral Sessions

Sessions expire automatically. No persistent tokens stored on any server.

Works Everywhere

Works on any desktop browser that supports Chrome extensions. Your phone handles authentication.

Lightweight

Minimal footprint. No bloat, no background processes, no tracking. Just what you need.

Get Early Access
