How to do recaptcha? those are my insigthsHow to do recaptcha? those are my insigths

I want to add some basic CAPTCHA for my future registration page in my Spring Boot-React web application.

💡 These are some main conclusions so far:

✅ You can access it from the Google Console. Search for reCAPTCHA.

✅ You can use v2 or v3 for free for 10,000 uses per month.

✅ V2 is the classic CAPTCHA with images/letters.

✅ V3 is invisible and checks for bots, giving a score. If it’s a low score, it’s treated as suspicious, and you can decide whether to show v2 (or not).

✅ A good suggestion is to implement both

✅ You should create separate keys for the DEV+QA environment and the production environment.

✅ A good idea is to set the public key for each environment in the application.properties file of the server.
