Don’t panic. You can still access your website with the safe URL
http://example.com/wp-login.php?hmw_disable=[secure_code]

This link appears in the plugin’s settings page and you should receive it by email too

 

Don’t have the safe URL?

Rename the plugin directory /wp-content/plugins/hide-my-wp to /wp-content/plugins/hide-my-wp1 so that the plugins wouldn’t hide the wp-admin and wp-login paths. Save it and all the plugin’s settings will roll back to Default mode.

Login using http://example.com/wp-login.php and you can rename the plugin back to /wp-content/plugins/hide-my-wp and continue the setup.

Make sure you remember the secure parameter, and it will be much simpler.
