2. Click on Accounts.

   

3. Click Sign-in options in the left hand side, and then select Never for the “Require sign-in” option if you want to stop Windows 10 from asking for password after it wakes up from sleep.

Method 2: Disable Windows 10 Require Sign-in on Wakeup Using Group Policy

1. Press Windows Key + R combination, type gpedit.msc in the Run dialog box and hit Enter to open the Local Group Policy Editor
2. In the left pane, navigate to Computer Configuration > Administrative Templates > System > Power Management > Sleep Settings.
3. In the right pane, you’ll see two policies labeled “Require a Password when the computer wakes (plugged in)” and “Require a Password when the computer wakes (on battery)“. Double-click on them to modify and set the policies to Disabled.
