What is Express Sign-In, anyway?
The Express Sign-In feature on the new Dell Latitude 7400 2-in-1 is a special security feature that makes use of Windows Hello technology in order to lock your device when you're away from the computer, and then unlock it automatically when you come back to it.
The device's IR camera, which is located above the screen, constantly checks for your face once you set up your Windows Hello facial recognition. If it stops detecting you, it will lock down your device after a certain amount of time (you can choose how long it takes in settings). Since the camera continues to remain active even in this locked, sleep mode state, it will immediately sign you back in and unlock your screen once it detects your face again. This is a fantastic feature if you need to get up for a bit, but don't want anyone to see what you're doing on your Dell Latitude 7400 2-in-1.
How well does it work?
In our testing, the Express Sign-In feature worked flawlessly and we had no issue with either the locking or unlocking functions. The camera itself is good and is capable of detecting facial patterns wonderfully, so you can expect Express Sign-In to work great on your own Dell Latitude 7400 2-in-1. However, if you do have problems with it, don't worry. You can simply disable the feature, and you can always sign in using a regular password, too.
