How to correctly compose htaccess for the admin panel?

Question

PHP

Here's what I ran into ...
I made the admin panel with one access point -
And now htaccess does not work - I honestly did it according to the "textbooks" - so I can hardly understand all these rewrites ...

AuthType Basic
AuthName "Thats protected Area!"
AuthUserFile /localhost/my_site/public/admin/.htpasswd
Require valid-user

Options -MultiViews
RewriteEngine On

RewriteBase /my_site/public/admin

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

Accordingly, the file with the password lies nearby.
Authorization window - I enter the login and password and "hello" ...

Server error!
