Passcode device policy
You create a passcode policy in XenMobile based on your organization’s standards. You can require passcodes on users’ devices and can set various formatting and passcode rules. You can create policies for iOS, macOS, Android, Samsung KNOX, Android Enterprise, and Windows desktop/tablet. Each platform requires a different set of values, which are described in this article.
To add or configure this policy, go toConfigure > Device Policies. For more information, seeDevice policies.
