What the author says it does

Contact Form 7 v5.1 dropped support for reCaptcha v2 along with the [recaptcha] tag December 2018. This plugin brings that functionality back from Contact Form 7 5.0.5 and re-adds the [recaptcha] tag.

If this plugin is installed before updating Contact Form 7 from v5.0.5 to v5.1.1 then it will carry over your old API keys. At that point you will just need to head to this plugins settings page to tell the website to use reCaptcha v2.

Once installed and configured it should be the same reCaptcha functionality you are used to in previous versions of Contact Form 7.

Questions the author answers

Will this plugin work with Version 3 keys?

No and yes. Google reCaptcha has specific keys for each API. If you are doing an upgrade from a previous version of Contact Form 7 to the current version you will need to re-add the Version 2 API keys using the traditional method. That being said you can set the plugin usage to default and it will use the inherit Contact Form 7 reCaptcha Version 3 API.

Where do I add my Version 2 keys?

Under Contact -> Integration you can see a “reCAPTCHA” service box where you may either “Setup Integration” following instructions from the Contact Form 7 documentation. If you already have keys set you will need to click the “Remove Keys” button and re-add them following the Contact Form 7 documentation.

I’ve added the Version 2 keys but nothing has changed

If you have added the Version 2 keys and you still do not see the reCaptcha show up on your forms please check the following:

In WordPress admin, under Contact -> reCaptcha Version please ensure that you have “reCaptcha Version 2” selected and saved.
On your contact forms please ensure that you have the [recaptcha] tag somewhere in the form.

Where this page's numbers come from

Read from the WordPress.org plugin API on October 31, 2026, when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
