Does DPAPI works if a user hasn't a login password?

All we need is an easy explanation of the problem, so here it is.

I was wondering if the DPAPI will still work properly if a user doesn’t have a a login password (like most of the home users). I can’t find this information on Google or in the official documentation and I can’t test it because the computers at work can’t be without a password.

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Yes, but it’s not quite as secure. DPAPI encrypts data with a master key, which is independent of the user password. When the user has a password, the master key is encrypted with the user’s password. Without a password, an attacker with local access (via another user account) might extract the master key. However, once an attacker has local access to the system it’s game over anyway. DPAPI is just a damage limitation system, really.

Note: Use and implement method 1 because this method fully tested our system.
Thank you 🙂
