App configuration
Threema Work allows to remotely edit app settings. You can control the app’s configuration, disable specific features, and the end user is relieved from setting up the app manually.
Configuration via Threema MDM
If you don’t use an MDM system for the app’s deployment, Threema MDM is a convenient way of controlling the app’s settings in the management cockpit. With Threema MDM, the same parameters that are available when using a regular MDM system can be configured. Learn more…
Configuration via MDM software
On Android and iOS, apps can be installed in a Managed Profile to separate personal and professional use. Apps that are installed this way can be remotely configured using an MDM system.
Threema Work supports the following platforms and profile types:
