How do I use Threema on a desktop computer?

  1. On your computer, open web.threema.ch (with a supported browser)
  2. In the Threema app, select “Threema Web” and activate the scanner:
    • Android: Main menu > “Threema Web” > "Initiate new Session" / QR code symbol
    • iOS: “Settings” > “Threema Web” > camera icon in the top right corner
  3. Use your mobile device to scan the QR code displayed on web.threema.ch

Hint: To avoid having to scan the QR code each time you use Threema Web, set a session password in the browser before scanning.
