At the moment, Microsoft is working on a new feature for Windows 10 that will automatically lock and then secure your device if the O.S. picks up that the individual has stepped away from the machine. The feature has been called Dynamic Lock in a variety of recent test-build efforts. Internally, the company has referred to this feature as “Windows Goodbye”, which certainly makes sense.
Presently, Microsoft utilizes something known as a Windows Hello camera to allow Windows 10 users to log into their devices with only their faces. This would definitely change things.
At the moment, individuals can use the Winkey+L combination to lock and secure their devices. It is believed that streamlining the concept with the Dynamic Lock feature represents an easier, safer method for protecting devices. It is likely that Windows is going to include the Dynamic Lock feature within a major release. In all likelihood, this is going to be in the April Windows 10 Creators Update.
