The feature is known as “Make your device passwordless,” and when is enabled, it will switch all the Microsoft accounts configured on you computer to the Windows Hello modern authentication.
How to make your device passwordless on Windows 10
Use these steps to enable passwordless authentication on Windows 10:

Under the “Make your device passwordless” section, turn on the toggle switch.
Once you complete the steps, those Microsoft accounts available on your device with switch to a modern authentication method using PIN, Fingerprint, or Windows Hello Face.
