Use Olvid with a computer


Olvid Web allows you to use Olvid with a computer (Windows/macOS/Linux) in a web browser. Your Android compatible device (smartphone or tablet) will serve as a gateway.

iOS


Olvid Web is not compatible with an iOS device.

Using Olvid with your computer (Windows/macOS/Linux) will be available with the standalone client, coming soon to Olvid.

Android
  1. Visit https://web.olvid.io in your web browser.
  2. Open Olvid on your Android device and tap (bottom middle button).
  3. Tap Scan and scan the QR code displayed on your computer.
  4. Wait for a 4 digit code to appear in your browser and enter it on your device.

Why another 4-digit code?

Connecting to a web client like Olvid’s requires creating a secure channel between your web browser and your Android device. For this to work regardless of the network configuration, this connection goes through a relay server (at Olvid, a WebSocket server) to which both devices are connected simultaneously.

If nothing was provided, it would be very easy for the relay server to make a “Man-in-the-middle attack” and to eavesdrop on all exchanges between the browser and the Android device.

As with adding a contact in Olvid, the 4-digit code displayed in the browser and entered on your Android device ensures that the channel is secure and that no one can eavesdrop.
