Information
This control determines whether a password is required before allowing access to the device via the touch screen. By default, iOS devices do not require a passcode to unlock the device after a period of inactivity, and the default Exchange ActiveSync policy setting applied for users not assigned to a mailbox policy does not require a passcode. It is recommended that a password be set.
Solution
From the AirWatch console, open the iOS device profile. Under Passcode verify that Require passcode on device is checked.
