Where it asks for a password. The search turns up nothing. Only on top of all windows or links to all sorts of WinLockers. It's not all that.

You need to implement the GINA library . Examples "google" are on delphi. Tip: if you write, then test in a virtual machine.

The fact is that a programmer should not have such an opportunity, so here you need to dig in the direction of system programming, and there are not so many system programmers on Delphi. Try to address on a specialized forum.

I don’t think it’s right to climb into the system ... This is the GUI in fact.

The fact is that this dialog has been transferred to the kernel level since the NT version in order to protect the machine from password interception. Therefore, you can not do with simple means. Therefore, it is more logical to heed the advice of @fart and do what is written in the article. There is simply no other way - just a banal substitution of the library.

So, it's clear... You can't do with this option with a couple of lines.
I also thought that antiviruses somehow display their inscription on the welcome screen, replace the picture? Is it possible to change the lock screen pattern in the same way? Another option, the Outlook mail program can display a message about unread letters on the lock screen. What is the mechanism? Is it possible to use it for your own purposes?
The data changes every 5-10 minutes. Only numbers are displayed.

the best variant of GINA, but due to complexity, it is no longer available.
