title: How to change Windows 10 login screen inactivity timeout?
body: <p>We are developing some MFA (multi-factor authentication) support on Windows. After entering the user password it will have other challenge like email/phone calls.</p>
  
  <p>But on Windows 10 we found that the login screen (not remote) will close after 30s of inactivity. In some cases the email/phone challenge may take more than 30s, and logon screen being closed will stop the email/phone wait.</p>
  
  <p>Is there any way, like registry, to change the Windows 10 logon timeout value?</p>
