Hi ??

I believe both of you have access to your database. In this case, you can navigate to the database management tool you are using (with SiteGround you can go to cPanel -> phpMyAdmin) and list the content of the database used for the application where you are facing the problem.
Find the WP Hide & Security Enhancer plugin is adding the following options in the _options table:
wph_settings
wph-previous-admin-url
At least these were the names of the rows during my tests. The wph-previous-admin-url one actually contains the custom string chosen for your /wp-admin login. So, if wph-previous-admin-url has value 123456 – use it like this:
https://yourdomain/123456
You should be redirected to the Dashboard login.
