The beta version of Threema 2.0 for desktop (and Threema Work 2.0 for desktop) is beta software that is still being developed. The desktop app is generally stable; however, you may occasionally encounter issues.
Please note that we don’t currently offer full customer support for the beta version. If the software does not meet your needs, please remove the linked device in Threema under “Settings > Threema 2.0 for Desktop (Beta).” This will also unlink Threema Beta on your computer. You can now use Threema on your mobile device as before.
These are the current limitations of the beta version of Threema 2.0 for desktop (subject to change):
- The beta version of Threema 2.0 for desktop only works with one mobile device (i.e., one phone/tablet) and up to two computers (Windows/Mac/Linux).
- The beta version for desktop is only available in English and German.
-
It’s required to keep Threema installed on your mobile device. Even though Threema works independently on linked devices, we recommend to open the app on each device at least once a week while connected to the Internet. This ensures new messages are downloaded to both devices.
- New messages sent or received will appear on both devices. Any messages exchanged before linking will not be displayed in the beta version.
-
At the moment, videos are sent as file messages. Recording voice messages and sending or receiving polls and locations will be supported in a future release. You can simultaneously use the current
desktop app or the web client to circumvent this limitation.
- Contacts can be added and modified but not deleted in Threema 2.0 for desktop (for consumers). This is not possible in Threema Work 2.0 for desktop.
- New message notifications may appear on your mobile device even if you have already read the messages in the desktop app. Open the affected chats on the mobile app to mark them as read.
- The “Do Not Disturb” setting is not yet supported by the desktop app.
- Enterprise proxies (network-based content filtering) are generally not supported.
-
If you have a new phone and move Threema to the new device, Threema 2.0 for desktop will be unlinked and may cause the Threema app to malfunction. To avoid this situation, please remove the linked device on your old phone before switching to the new one (the message history will be deleted in the desktop app). You can then add the device again on the new mobile device. Alternatively, you can manually reset the desktop app, cf. this FAQ entry.
We are aware of the following technical issues and plan to resolve them with a future update:
- Perfect Forward Secrecy (PFS) is not supported when using the beta version of Threema 2.0 for desktop.
