There are two main ways to password protect a page or website in RapidWeaver, we'll cover both options below.
Password Protection Addons (Paid Option)
If you’ve just started using RapidWeaver, or you’re not comfortable creating files on your FTP server, then purchasing a third-party add-on is the best option for you. It's easier, and quicker, than creating your own solution. The best options currently available are the Page Safe stack and the Lockdown plugin.
Both of those add-ons are paid-for, but they do make adding a username and password to any page(s) very easy.
htaccess Authentication (Free Option)
If you’ve done a bit of coding before, and you don't want to purchase an add-on, then using the htaccess authentication method is the best option.Note: This solution is not something you can achieve from within RapidWeaver. You will need to login to your FTP server and create some files.Having said that, it is very easy to password protect a folder or directory with .htaccess. The method is generally known as “htaccess authentication” or “htaccess password protection”, and it works by you logging in to your FTP server and creating two files, called .htaccess and .htpasswd, in the directory you want to password protect.
