Microsoft is taking its disdain for passwords to a new level. It just released a Windows 10 preview for Fast ring Insiders that gives you the option to make all accounts on a particular device "passwordless" when logging into the operating system. Flick a switch in settings (under Accounts -> Sign-in options) and a password won't work at all. You'll have to use Windows Hello face recognition, fingerprint detection, a PIN code or a physical security key to unlock your system. If you don't already have Hello enabled, Microsoft will walk you though it the next time you sign in.
The feature is only available on a "small portion" of users' PCs at the moment, so it may take a week or more to see it. And since this is the Fast ring, you shouldn't be surprised if there are any bugs.
There are other reasons to consider the release, at least. The Your Phone screen feature now works with more Surface devices, right up to newer hardware like the Surface Pro 6 and Surface Laptop 2. You can also quickly create calendar events from the taskbar. So long as you're prepared for glitches, this could be a meaningful sneak peek at where Windows is going in the near future.
