How can you use recaptcha for multiple forms in the same page?

[@CodeJava]

Refer to the official Google ReCaptcha document. Also it is necessary to have multiple forms in a single page? I rarely face such case. Only one form is enough most of the time.

How do I validate the OTP, block the user first or send an email with the code and if it is valid I let it go to the dashboard

[@CodeJava]

either way is okay. But I prefer sending email with the code.

[@premudayan]

Great video. Do you have this sample code available for download? Thank you

[@CodeJava]

currently no. I will publish a corresponding article in which you can copy and download the code.

This is great combination with OTP Email tutorial, thank you.
It always returns score 0.9, how can I get score below 0.5?

[@CodeJava]

Maybe by controlling the mouse using keywords to fake a bot. Let try and let me know.

[@ossenbrueck]

manipulate the DTO before returning it

[@user-no1ds1uh4b]

I always getting {"success": false, "error-codes": [ "invalid-input-response" ]

[@CodeJava]

check docs of Google reCaptcha to understand its meaning.

[@hendisantika]

Is there any github repo link for this example? Thanks

[@CodeJava]

currently no code on GitHub.

[@feri6320]

how do you exclude the login?logout from filter?

[@CodeJava]

You can check the request URL, if it ends with login?logout then bypass the rest of the code.

[@hieu.nguyenvan6272]

Pls! What if I configure with xml?

[@ossenbrueck]

switch to annotation based Spring Boot development
