Google reCaptcha is like a security guard for websites. It stops spam and robots from messing with things. It’s commonly used in places like when you log in, sign up, send a message, or leave a comment on a website.
There are two types of Google reCaptcha:
- v2 – You have to pick pictures to answer a question.
- v3 – This one works in the background, and you don’t even see it.
In this guide, I’ll show you how to add Google reCaptcha v2 to your form and make sure everything is secure in your CodeIgniter 4 project.
