Failed Login Screen/Redirect

So functionally the registration page and login functionality are all working. However, I know I’ve seen an actual login page that’s only logging in and not registering. But currently any failed log-ins from the normal dropdown box leads to the wp-login page. I need it to go back to that default front-end login page.

If it’s part of a login page that was created by the theme and has some extra code on it can I get a copy of that, or how do I set up the slugs and templates for that to work again?
