How to restrict access to wp-admin and wp-login.php in Wordpress portal?

Question

WordPress

Good day!
There is a portal system on wordpress with a custom registration and authorization form (pop-up window) through which users of the Authors group enter.
In addition to this, wordpress social login works which accesses wp-login.php
1. It is necessary for authors to restrict access to the admin panel, since they have their own profile in buddypress.
2. Deny access to all links /login, /wp-admin, /admin, /wp-login.php to all users, but so that authorization through the social. networks worked and logging out of the buddypress profile also worked.
On a good note, I come to the conclusion about the need for a single form of authorization, either for the admin or for a simple author.
How can the above restrictions be correctly implemented? No plugins!

Hello. Have you looked at the Users Role Editor plugin by any chance?
And for a personal account and a unified authorization system, see the Wp Recall plugin
