Hi Erik,
As the author stated a few postings before this one, she still maintains the plugin, just does not have time to answer a lot of help questions about the plugin.
I seacrched the internet and found that indeed if you disable the plugin, things should just go back to the normal login. I will try this in a test envirement as well to be sure:

Hide Your Login Page
Malicious parties can attack your login page because they know that a default installation of WordPress can be logged in at https://www.yourwebsite.com/wp-admin/ and at https://www.yourwebsite.com/wp-login.php. Moving the location of your login files makes it very difficult for hackers to perform a brute force attack.
There are good plugin solutions available that allow you to do this easily:
Rename wp-login.php – A multisite friendly plugin that allows you to change your login page. Once activated, the wp-admin directory and wp-login.php page will be inaccessible.
Hide Login+ – Allows you to change name of your login page, admin area, logout page, and forgotten password page.
Lockdown WP Admin – Another useful plugin that can conceal your admin area and login page.
If you forget the new location of your login page and admin area, you can reset everything by simply deactivating the plugin in question. You can do this by renaming the name of the plugin folder contained within /wp-content/plugins/. Alternatively, you could delete the plugin and reinstall it once you have logged back in to your website.
