How can I change the start page on the Sierra?

I'm not talking on the desktop or screen saver. I want to talk about the page that appears when you turn on your iMac or when you wake up. This is the page where you enter your password. Sierra that's so terrible ugly. Is there a way I can change it?

Select a picture - once you have your image to the right size and dimensions, save or export to your desktop as a PNG file and name it com.apple.desktop.admin.png.

Then, from the desktop, use Cmd-SHIFT-G hotkey to access the go to folder window, type the following path in the box and click OK.

/Library/Caches/

A new Finder window appears showing the contents of the path, and you will see a file called "com.apple.desktop.admin.png" in the folder. Make a copy of this file and store it as a backup if you wish (although we'll describe in a moment why it is not really necessary) and then drag and drop the version of the file that you created on your desktop to the folder Caches, agreeing to replace the existing file when you are prompted.
