Many users nowadays have a mobile focus. Working away from any centralized office or workspace, many users find themselves being productive everywhere–from coffee shops to client offices to hotels and even 30,000 feet in the air when traveling. Business knows no barriers!

With this decentralized model, it is easier for devices–as well as the data stored on those devices–to be lost or stolen.

As a simple yet effective way to brand devices and allow for important advisory information to be displayed, Apple created a screen lock message that can appear on a device’s logon screen with any custom message set by the user or the company that owns the device. This is similar to Windows devices using Group Policy or registry modifications to display important information at the logon screen.

Additionally, if you wish to customize and format the lock screen message (e.g., you may want to include a return address in the event that the device needs to be mailed back to you), it can be typed into a word processor and then copy and pasted into the text box.
