You can protecting directory on apache web server so no unauthorized people may access it, in here we would like use .htaccess file (there is DOT at front htaccess file name) on apache root directory.
root:# cat .htaccess
AuthType Basic
AuthName "Restricted Access"
AuthUserFile /home/apasswords
Require user anjani
root:# ls -al .htaccess
-rw-r--r-- 1 root root 103 Oct 9 08:38 .htaccess
Make password for user anjani and save it on file /home/apasswords
root:# htpasswd -c /home/apasswords anjani
New password: ******
Re-type new password: ******
Adding password for user anjani
root:# cat /home/apasswords
anjani:jBdra06B5M54.
The password on the appasswords is encrypted
root:# ls -al /home/apasswords
-rw-r--r-- 1 root root 21 Oct 9 14:18 /home/apasswords
Done.
