Our servers do not support custom .htaccess files.  However, our control panel does offer directory password protection through it's interface. 

WARNING!  You should only attempt to password protect new directories which you have created.  Do not attempt to password protect directories which were part of your hosting account configuration created by us.

WARNING! Uploading customized .htaccess files will cause irreparable damage to your hosting space requiring complete deletion of your hosting space and settings (including mailboxes) to reset the space.  There may be a $25 service charge for resetting your space if it was damaged from your uploading an .htaccess file.
