What is Secure Sign in?
It is very important to keep your PC as secure as possible. One way to do so is to enable secure Sign in, so that all users need to press Ctrl+Alt+Delete to log on securely. After pressing Ctrl+Alt+Delete the users are asked to type a valid username and password to access the computer.
Secure logon provides an additional layer of security for your computer. It ensures you that the authentic Windows logon screen appears and thus it stops any type of mimic of your personal log in information. It means, if you have enabled the Secure logon or Secure Sign in in your computer, no other program (such as a virus or spyware) can intercept your user name and password information as you enter it.
