InstallLock
WordPress Security Plugin That Goes Beyond Passwords
Stop Unauthorized Plugin Installs and Updates.

Your WordPress website may be at risk.
Hackers who gain access to an administrator account or compromise a service connected to your website may be able to install malicious plugins, disable security tools, or make dangerous changes without your permission. Some attacks don’t even require a normal WordPress login.
InstallLock adds an independent layer of security. Software changes remain locked until you authorize them with a six digit code from your authenticator app. Simply having access to a WordPress administrator account isn’t enough to authorize these changes.
InstallLock Free protects WordPress core and themes. InstallLock Pro extends that protection to your plugins.
Why Plugin Protection Matters
WordPress plugins do more than add features. They can run powerful code on your website. A malicious plugin could steal sensitive information, damage your website, or create a hidden way for attackers to regain access later.
InstallLock Free provides valuable protection for your WordPress core and themes. InstallLock Pro takes that security further by protecting your plugins against unauthorized installations, updates, activations, deactivations, and deletions.
Why is this important? Even if attackers gain access to a WordPress administrator account or compromise a connected service, InstallLock Pro requires separate authorization from your authenticator app before these plugin changes can be made.

Free protects your WordPress foundation. Pro protects your plugins, too
