Most WordPress webmasters share their content with the world. But in certain situations, you may want to keep your content to yourself and available to those who you approve of. Friends Only is a superb plugin that limits access to your blog to only those whose email address you have white-listed.
The plugin is quite simple to use. Just enter the email of people who you’d like to have access to your website. Friends Only keeps track of the successful and failed attempts and sends you notifications to the email address you have provided it with. Friends Only does block access to your RSS and ATOM feeds. Since it only requires an email address to provide access, it won’t make your friends too frustrated.
Friends Only is not the most secure way to keep a private blog. But it should work for simple blogs with no super sensitive material. A nice way to make sure only people you trust gain access to your blog’s content.
