WordPress 2 still doesn’t have the feature to support HTTPS access to the admin area when the rest of the blog is accessed in HTTP. I don’t feel comfortable to access the admin area in unencrypted connections. I believed many people using WordPress also had the same thought with me.
Fortunately, there was a smart guy out there managed to create a WordPress plugin that secured the access to the admin area. The plugin is called Admin-SSL. The plugin supports both shared and private SSL certificates.
