Use Olvid Web

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.

iPhone iPad

Olvid Web is not compatible with iOS devices, but you can use Olvid on Windows, macOS and Linux computers.

  1. Visit 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.
