If you log in to Windows with a Microsoft account, the Windows 10 sign in screen shows the name and email address for the last user that signed in. It’s convenient, but if you use your computer in public or leave it unattended, you might not want people being able to see that personal information. Here’s how to hide it.
The lock screen itself does not show your sign in information, but with just a click or tap, anyone can reveal the sign in screen that does. By default, the sign in screen shows your name and email address (or username if you’re not using a Microsoft account) and whatever picture you’ve associated with your account. If this is information you’d rather not have passers-by privy to, we’ve got the fix.
