On private computers that are only used by one user, it really makes no sense to have to enter a password every time you startup. Good thing Windows 10 offers a relatively well-hidden feature for this. Use the Windows+R hotkey to open the Run window, type “netplwiz” and confirm with entering. In the User Accounts window that now opens, bring the Users tab to the front, uncheck the You must enter a password and username to use the computer before you can use the computer option, and click OK.
For security reasons, we then need to enter the username and password and click OK to confirm. Restart the computer to check that the automatic login feature is working.
Conversely, if you’re using an online Microsoft account with a Windows Hello sign-in method (PIN or biometric authentication), you first need to open the Windows Desktop with Windows+I, select Accounts, and click Sign in in the left-hand column. Set Sign in to Microsoft Accounts with Windows Hello to Off.
Then we need to do the same as for a local account.
