In Windows 8, how do you disable the unlock password for Microsoft Accounts?
Solution 1:
To turn on automatic sign in for a local user account or Microsoft account:
press Win+R to open the Run dialog box, then type in
netplwiz
and press Enterselect the user name of the local user account or Microsoft account that you want to have Windows 8 log on to automatically at startup
uncheck the "Users must enter a username and password to use this computer" box, and click/tap on OK
enter the password of the selected local user account or Microsoft account twice, and click/tap on OK
Solution 2:
If you have a Microsoft account, utilize netplwiz
in run, and disable the password, upon reboot your system then gives two options for signing in; a local account and the Microsoft account. The local account will not require a password, but the Microsoft account does require a password.
