Password Protect Site using htaccess

To password protect a web site or a sub folder using .htaccess, create a .htaccess file in the folder.

vi .htaccess

Add following content

AuthType Basic
AuthName "Restricted Content"
AuthUserFile /etc/apache2/site-logins
Require valid-user

In this case, i used /etc/apache2/site-logins as AuthUserFile, this will store all user and password. You can change this file path to whatever you need. Make sure it is not accessable from public, so keep it outside of document root of your web site.

Now create a user with command

htpasswd -c /etc/apache2/site-logins USER_NAME_HERE
