License Key

All Wordfence installations need a license key, also known as an API-key. The key can be a free key or a Premium key.

Installing your Free License Key

Please be advised that Wordfence Free has a 30 day delay on receiving firewall rules and malware signatures. For real time firewall rules and malware signatures, protect your site by upgrading to one of our Premium products.

How to get a free key

There are currently two ways to request a Wordfence Free license key – either when installing the Wordfence plugin on your WordPress site, or through the Wordfence license page. To request a free key from the license page, you must first have a registered user account. From the license page, select the “Get a Free License” button at the top of the page. This will launch a pop-up that requires a site URL before you can select “Get a Free License” to receive your new Free license key. Your new key can then be copied and pasted into the Wordfence Security plugin by selecting the option to “Install an existing license” from the WordPress Plugins page.

If requesting a free key as part of the Wordfence plugin installation, once the Wordfence plugin is installed you will be prompted to “Get Your Wordfence License”. This will bring you to Wordfence’s product web page where you can view our full suite of products to determine the best option for you. Select the button for your desired product. If your desired product is Wordfence’s Free license, select the “Get a Free License” button. This will launch a “Get Wordfence Free” pop-up where you’ll input your valid email address, optionally subscribe to our Wordfence mailing list to receive news and alerts, accept legal Terms and Conditions, and select “Register”.

Successfully completing this pop-up and selecting the “Register” button completes your Free license registration and sends your license key as well as installation instructions to the email provided. Note that this is not the end of your Wordfence installation, which must be completed for Wordfence to be successfully installed and activated.

Installation instructions

Open the email containing your Free Wordfence Security license key. Click on the “Install License” link within the email if it’s within 24 hours of the time you registered for a Free license. This link will automatically install the Free Wordfence license key from the email you received to your requested website.

If installing manually, or in the event that the automatic install expires or fails, you will need to copy and paste the license key into the Wordfence Security plugin by selecting the option to “Install an existing license” from the WordPress Plugins page. Copy the key from the email, paste in your license key and read/select the checkbox for legal Terms and Conditions, if applicable, before selecting the button to “Install License”.


Problem receiving installation email

Please note that emails may not be delivered successfully to disposable or temporary email addresses. In the event you are not receiving the email with your Free license key and installation instructions, first try the following:

  • Check your Spam folder
  • Verify the spelling and email address provided are correct
  • Make sure your email mailbox isn’t full
  • Add “” to your email client address book, and “” to your allowlist
  • Retry with an alternate email account

Registration process shows two different URLs

When registering for a free license, some site owners may see a message like:
Your site is registering with the URL but the admin URL we received from your site is

This usually means that the Wordfence plugin running on your site got two different URLs from WordPress for the site URL and admin URL.

If you recognize both URLs as a part of your site or hosting plan, it is generally ok to proceed and usually will not affect your Wordfence installation. If you are not sure about one of the URLs, you can contact Wordfence support using the buttons near the top of this page.

Some examples we have seen include:

  • Multi-language sites may have two different URLs like and
  • In rare cases, a host may assign a different URL for administration, and you may see domains like If you see significant differences like this, you can check with your hosting company if you are not sure.
  • If one URL uses plain http and the other uses https, this should not be an issue as long as you started the registration process from the prompt in the Wordfence plugin on your site. Some sites force http in .htaccess or Nginx configuration files, even if WordPress itself is still set to use plain http.
  • If testing on a localhost site or a virtual machine, you may see “localhost” or your machine’s IP address in some cases.
  • URLs containing non-latin or accented letters may appear in “punycode”, a standard for encoding non-ASCII characters. When this occurs, parts of the URL begin with “xn--“. This includes domains using languages with completely different characters, like Japanese, as well as latin characters with modifiers like accents or umlauts. If you see a URL like this while registering, but aren’t sure if it is valid for your site, Wordfence support can help confirm if it matches your domain.

Error attempting to install the Wordfence license key from the email to your website

If you attempt to “Install License” after 24 hours, you will no longer be able to automatically install the Wordfence license key. Additionally, if you are in a different browser than the one used when requesting your Free Wordfence license, you will be unable to automatically install your new Free Wordfence license. In those cases you will need to manually copy and paste the key from the email to complete the activation of Wordfence Security.

If you copy/paste your new Wordfence license key into the “License Key” field and you receive a message “Error Installing License”, first verify that you did not inadvertently copy only part of the license key or overwrite a portion of the license key when pasting the key in to the text box. When in doubt, clear out the field and recopy/paste the key into the “License Key” field. If this does not work, return to the WordPress plugin page and request a new Free key by selecting the button “Get Your Wordfence License”.

From here you can do the following:

How many license keys do I need to buy?

Each installation of the Wordfence plugin requires a unique Wordfence license key. If you have a WordPress Multisite, you only need one license key because a WordPress Multisite is a single installation of the WordPress file system and only has one installation of the Wordfence plugin.

You can not protect more than one WordPress installation (single or Multisite) with one license key unless it is a staging or development site of the accompanying production site. See the section below for staging sites to learn more about this.

Use Wordfence license on staging

A Premium, Care, or Response license that is valid for a site can also be used to enable Premium functionality to a corresponding staging or development site. The Security Incident response services that come with Care or Response licenses can be extended to a staging or development site for an additional cost of $199 USD/site.

We are initially opening up this capability to the following common subdomains below and your license key will work automatically on these staging or development site subdomains. If you have different staging or development URLs then these will need to be enabled by Wordfence Premium support staff. Please send in your staging or development site URLs via our Premium support ticket system.
