How to add reCaptcha 2 to Contact Form 7

reCaptcha is a great “bot” detection solution from Google. Google watches the pattern of user interaction to decide whether it is a “bot” or a real user. It is near impossible for a “bot” to simulate those patterns. So reCaptcha succeeds in blocking spam most of the time. The reCaptcha version 2 is simple and user-friendly. The user is to check a box saying “I am not a robot”. However, sometimes, this version of the captcha also throws some picture puzzles too. Contact Form 7 version 5.1 and later uses reCaptcha 3. It does not support reCaptcha version 2 anymore. However, you can use reCaptcha 2 with even the latest Contact Form 7 using another plugin. In order to use version 2 of reCaptcha in Contact form 7, install yet another WordPress plugin: Contact form 7 -reCaptcha 2
