Hidden wp-admin

You’ll find the login screen on whatever url you tell the plugin to put it on. This plugin allows you to change /wp-admin to whatever you want.

You have two options. You can just hide the /wp-admin/ URLs. So if somebody went to https://domain.com/wp-admin/, it would be a 404 NOT FOUND. But to login, just go to https://domain.com/wp-login.php

You can also set the login URL. This will change /wp-login.php to /login/ or whatever you please.
