Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Wordpress HTTP Authentication Plugin

HTTP Basic Authentication for Wordpress

This gist contains a simple plugin that automatically logs in a user into Wordpress with the login name provided by HTTP basic authentication. If no HTTP authentication is present, the plugin exits the rendering process; if a user is logged in who does not have a Wordpress account, the plugin also exits.

This plugin is intended for internal blogs, for example for a team, which are anyway protected by HTTP basic authentication and where you want a single-sign-on solution.

Installation

Simply paste the PHP file into the wp-content/plugins folder and then enable the plugin in admin panel
