1. Do you login using an administrator account or guest account?
2. Are you using a Microsoft Account or Local Account?
I would like to inform you that the computer will prompt you for a password if you are using a Microsoft Account in your computer.If you are using a Local account, I suggest you to login to the computer as an administrator and follow the below mentioned steps and check if it helps.
I would suggest you to refer to the steps if you want to disable the login password
a) Type “netplwiz” from the Start Screen of Windows 8 and then press “Enter” key on the keyboard.
b) On the “User Accounts” page, check if you have selected the option “Users must enter a user name and password to use this computer” for the Guest Account to set auto-login. If this option is selected, then uncheck this option for the Guest
account and then click on “Ok”.
c) Restart the computer and check the issue.
Note: If your local account is an administrator type of account, then it is strongly recommended to keep your account password protected for security purposes. Otherwise anyone will be able to use your account, and just be able
to select your account and press Enter in a UAC prompt to run as administrator.
