Users with multiple devices


Each app instance requires an individual license. If Threema Work is used on multiple devices at the same time, a separate license is required for each device (cf. Terms of Service).

To use Threema Work on your desktop, a mobile device on which Threema Work is installed is required; however, no additional license is necessary.


  • A Threema ID cannot be used on multiple devices (or in Threema and Threema Work) at the same time.
  • Per app, only one ID can be used at a time.
  • An email address or phone number can only be linked to one Threema ID at a time. Linking the sameemail address or phone number to different Threema IDs is not possible.
