Deze plugin is niet getest met de laatste drie grote versies van WordPress. Mogelijk wordt het niet meer onderhouden of ondersteund. Er kunnen ook compatibiliteitsproblemen ontstaan wanneer het wordt gebruikt met recentere versies van WordPress.

Two-factor authentication (formerly IP Vault)


IP Vault lets you protect your WordPress backend – and any other part of your website – from non verified users.

IP Vault Firewall also preserves your server ressources and bandwidth by blocking hacking attempts before they reach your site.

How does it work ?

Requests to protected files and folders are redirected to the Authentication Page. IP Vault unlocks user’s IP addresses using a key
that is emailed for authentication. Once users verify their account, they can access all restricted areas. Users are automatically verified on registration.

What is protected ?

Out-of-the box, IP Vault restricts access to .php and .phtml files, as well as wp-admin folder, which are frequently exploited by bad bots and hackers.
You can choose which part of your site to protect. Need to make the whole website private ? No problem, just restrict access to /.

The story behind this plugin

In the past 20 years, I have been monitoring a few dozen client sites to prevent malicious access. I have also helped a great number of people to clean their website from malware.
I noticed that even marginal WordPress sites or non-wordpress PHP based sites are constantly exposed to hacking attempts.

Almost all exploits I have seen work by either calling a vulnerable PHP script already on the server, by adding such a script or by injecting their own code into an existing script.

I have tried and tested quite a few security plugins. They can be quite complex to set up and to maintain. Some security plugins try to block access to vulnerable files by comparing requests to a blacklist.
These tend to become quite large and need frequent updates to be efficient. Others use geo-blocking services to block requests from certain countries. However in my experience, hacking attempts can come from just about any location.

I thought there must be a better way using whitelists for verified users instead. And that’s how the idea for IP Vault was born.
