What is a session and what is the purpose of the session password?

To use Threema Web without having to scan the QR code each time, you can set a session password.

On web.threema.ch, enter a session password before scanning the displayed QR code. To use Threema Web the next time on the same computer, you can simply enter this password (instead of scanning the QR code again).

This way, it’s also possible to use Threema if your mobile device isn’t present (provided it’s connected to the Internet).

The different sessions are listed in the Threema app, where you can remove and rename them.
