How to protect alias with htpasswd file

Just a simple reminder :

1) Create passwd file:
htpasswd2 -c /etc/apache2/htpasswd USER -> insert password

2) verify grant on path

3) create alias

Alias /protected /root/path
<Location /protected >
        AuthType Basic
        AuthName "download for protected "
        AuthUserFile /etc/apache2/htpasswd
        Require valid-user
</Location>
