Windows 10: BIOS password used for winlogon auto login

I have heard that it is somehow possible to pass the BIOS hardware boot password on to Windows and have winlogon auto login a user based on the password obtained from BIOS.


Does anyone know how this can be accomplished? I'm speculating that BIOS may leave credentials in EFI variables and winlogon is somehow flagged to look for them when the system is started. Thoughts?

How to auto login windows 10 if i use Microsoft account?

I didn't solve this by your suggestion. However, i reinstalled windows10, and log in with Microsoft account from start. Then netplwiz works well.

I found a interesting phenomenon. After unchecking the box of netplwiz, and type a wrong password, netplwiz will also exit with no error. Does it mean netplwiz only sotres the password i input and use this for logging in?

I have two hypothesises about netplwiz.

1. auto login feature is a kernel feature, netplwiz just call this feature, the password you need to input after unchecking the box is just for authentication of current user.
2. auto login feature is provided at userspace by netplwiz. the password you need to input after unchecking the box is stored somewhere and netplwiz will use this password to log in windows

At first i think first one is correct, but now it seems that second is correct, am i right?

 

Password issue

After going through the steps to make a new password, after a week or two, my login credentials are no longer valid. I'm forced to make a new password all over again. It seems to happen if I don't login in a certain period of time. Does our passwords expire???

Hi,

Thank you for posting your query on Microsoft Community forum.

I would suggest you to provide some information to help you better.

• Are you referring to BIOS password as Boot password?
  
• Is it a login password which you are referring when Windows starts?

If Login password, provided you are using Local Account on Windows 10 you may follow the below steps:

• Press Windows + R keys to open Run command
  
• Type " control userpasswords2 "
• Select the account and uncheck "user must login with password"
• Select apply and Ok.

If Boot password you may have to contact your computer manufacturer.

Keep us posted to help you better.
