Apache Password Protection

To use Apache to password protect a site you can set the following lines in the .htaccess file for the site

AuthUserFile /home/user/.htpasswd
AuthType Basic
AuthName “Guest”
Require valid-user


The following command will generate a .htpasswd file and request the password that will be set

htpasswd -c /home/user/.htpasswd
