How do I replace the lock screen?

Hi there,
I just got myself Ubuntu Budgie and I really love it! Way better than Windows (any day!) and way better than the default Gnome look! However, there’s one thing that I don’t like and that is the login screen. Is there any way to replace it with a different logon screen and then configure it for starting on itself by adding something to ~/.bashrc ?

Kind regards,

I bumped into Linux and fell in love with it in first sight! :heart:
