Wow. This is fun. I remember my Windows98 had the same feature. You just use Administrator with empty password and you're in. Apple is finally catching up.
Also reminds me of https://youtu.be/BVL8_ne4WZo?t=19s
> That isn't a login screen for Windows 98, it's a login for Microsoft Networking (which the box shows). If you had any shared mapped drives, network privileges, etc they wouldn't work if you cancelled. If you had multiple profiles set up, you wouldn't get those either. Win98 wasn't intended to have password security.
