Based on my experience, these steps are the fastest way to login if you cannot login after install this plugin :
1. Look into the database
2. Find a table named wp_options
3. Inside wp_options table, find ld_hide_wp_admin
4. Edit this ld_hide_wp_admin and type yep in option value box, then save.
5. Find ld_login_base, delete login base (the special name you created for login) in option value box, and leave it blank, save.
6. Refresh the database, then Logout.
7. Login to your website using https://domain.com/wp-login.php
8. End
