You can create more complex passcodes than the four-digit minimum device passcode. The app level passcode can be shared with other productivity apps, for example, VMware Boxer.
You designate the local passcode requirement for an application in the Workspace ONE UEM console. Navigate to Groups & Settings > All Settings > Apps > Settings and Policies > Security Policies > Authentication Type.
When Passcode authentication is configured, users are prompted to set an app level passcode if no other productivity apps exist, or they are prompted to enter their shared passcode with other productivity apps.
If Passcode authentication is not configured, a device passcode is required on iOS devices.
