Captcha V3 Score
Jeannine Lander
reCAPTCHA v3 returns a score for each request without user friction. The score is based on interactions with your site and enables you to take an appropriate action for your site. Register reCAPTCHA v3 keys on the reCAPTCHA Admin console.
reCAPTCHA v3 will never interrupt your users, so you can run it whenever you like without affectingconversion. reCAPTCHA works best when it has the most context about interactions with your site,which comes from seeing both legitimate and abusive behavior. For this reason, we recommendincluding reCAPTCHA verification on forms or actions as well as in the background of pages foranalytics.
reCAPTCHA v3 returns a score (1.0 is very likely a good interaction, 0.0 is very likely a bot).Based on the score, you can take variable action in the context of your site. Every site isdifferent, but below are some examples of how sites use the score. As in the examples below, takeaction behind the scenes instead of blocking traffic to better protect your site.
reCAPTCHA learns by seeing real traffic on your site. For this reason, scores in a stagingenvironment or soon after implementing may differ from production. As reCAPTCHA v3 doesn't everinterrupt the user flow, you can first run reCAPTCHA without taking action and then decide onthresholds by looking at your traffic in the admin console. Bydefault, you can use a threshold of 0.5.

reCAPTCHA returns a score for each request based on the interactionswith your site, regardless of the key type. After you receive the score fromreCAPTCHA, you must interpret the score and take appropriate actionsfor your site.
Verify that action matches the expectedAction.For example, a login action should be returned on your login page.If there is a mismatch, it indicates that an attacker is attempting to falsifyactions. You can take actions against the user interaction, such as addingadditional verifications or blocking the interaction to prevent anyfraudulent activities.
The scoring system of reCAPTCHA is an expansion from priorversions of reCAPTCHA to allow greater granularity in responses.reCAPTCHA has 11 levels for scores with values ranging from0.0 to 1.0. The score 1.0 indicates that the interaction poses low risk andis very likely legitimate, whereas 0.0 indicates that the interaction poseshigh risk and might be fraudulent.Out of the 11 levels, only the following four score levels are available bydefault: 0.1, 0.3, 0.7 and 0.9.
Now I wonder what would be a non fraudulent score. If I use my email address I get a score of 0.89.Would it be ok if I assess all scores >= 0.7 as non-fraudulent? What would be a good starting point as a minimum score?
On the recaptcha enterprise website it states:"With low scores, require MFA or email verification to prevent credential stuffing attacks."Where could I set up MFA or email verification? Is there a documentation about it?
When you create an assessment, reCAPTCHA Enterprise provides a score that helps you understand the level of risk posed by user interactions. You can confirm or correct reCAPTCHA Enterprise's assessment later, when your website has more information about user interactions to determine whether they were legitimate or fraudulent. You can send the reCAPTCHA assessment IDs back to Google with the labels LEGITIMATE or FRAUDULENT to confirm or correct the assessment made by reCAPTCHA Enterprise.
Compared to previous versions of reCAPTCHA, reCAPTCHA Enterprise's scoring system now allows for more precise responses. There are 11 levels of scores in reCAPTCHA Enterprise, with values ranging from 0.0 to 1.0. A score of 1.0 indicates that the interaction is low risk and most likely genuine, while a score of 0.0 indicates that it may be fraudulent. Only the following four score levels, out of the 11 levels, are available by default: 0.1, 0.3, 0.7 and 0.9.
NOTE:This is a sample implementation, the score returned here is not a reflection on your Google account or type of traffic. In production, refer to the distribution of scores shown in your admin interface and adjust your own threshold accordingly. Do not raise issues regarding the score you see here.
Google reCAPTCHA v3 is a method of determining the likelihood that a form submission was carried out by a bot. Unlike reCAPTCHA v2, which offers a challenge to the user before submitting the form (yeah those annoying images that pop up asking you to select every polka-dot colored fire hydrant), reCAPTCHA v3 does not offer any challenge but passes a score to Marketo that can be used for triaging after the form has been submitted.
Now that you know how to set up a SPAM filter in Marketo using the Google v3 reCAPTCHA integration you can turn your attention from dealing with SPAM form submissions to upskilling your automation game with the Marketo API. The Marketo REST API Crash Course will teach you the fundamentals you need to start making API requests and automating your marketing operations workflows.
At Waitwhile, we take security very seriously. One important security measure we have in place is detection and prevention of scripts and bots that could be used to flood your waitlists and booking calendars. We use Google's reCAPTCHA feature to keep malicious software from engaging in abusive activities on your Waitwhile flows, while not preventing your legitimate customers from using it.
However, there are instances where the reCAPTCHA challenges may be triggered unintentionally for some your customers. This article will help you to to troubleshoot and resolve these false positive if they occur.
By default, if the score is 0.5 or lower the user is suspected of being a bot, and in such cases Waitwhile will display an error message and they will not be allowed to complete the registration process.
Our Support team can help manually change your reCAPTCHA score threshold so that the bot prevention is less sensitive. If using our API, this can be changed by calling the Update Location endpoint with the attribute recaptchaMinScore set to have a value between -1 and 1, or you can set it to -1 to disable it completely.
Hey yo!
I have implemented score based reCaptcha enterprise(invisible) on my web project. Documentation specifies that when a low score is returned in an assessment, typically there will be a reason to explain the reasoning behind the low score, but this don't happen with any score. Should i configure something specific to get the reason for low scores?
Good Day and welcome to the community!Based on your scenario, here is a good read regarding interpreting an assessment.[1] Here you can see details on how the score is interpreted and some helpful information on your use case.
Thanks for your attention!
Inside of "Understanding reason codes" section in the documentation, we have this information:
"Some scores might be returned with reason codes that provide additional information about how reCAPTCHA Enterprise interpreted the interactions."
What Google consideres before send or not the reason code? I have this doubt because, when i got a low score(like 0,1 or 0,3), the assessment doesn't return any reason inside of RiskAnalysis object, only the score.
reCAPTCHA v3 returns a score for each request without user friction. The score is based on interactions with your site and enables you to take appropriate action for your site. Register reCAPTCHA v3 keys here.
The Google reCAPTCHA v3 Score Threshold can be adjusted at _recaptchascorelimit. It should be a value between 0 and 1, default 0.5 (1.0 is very likely a good interaction, 0.0 is very likely a bot). For more details regarding the score, please view _the_score. In the meantime, in your reCAPTCHA admin console, you can check score distribution which can be helpful for you to determine how to adjust the reCAPTCHA v3 score threshold for your site.

reCAPTCHA scores run from 0.0 (bot) to 1.0 (person). hCaptcha Enterprise scores are risk scores, and thus they run from 0.0 (no risk) to 1.0 (confirmed threat). See the hCaptcha Enterprise documentation on scores for more details. (Requires login to Enterprise account.) This means you should invert any score checks in your score consumption code.
On the captcha tickbox on a log in to a secure zone on one of our sites, there seems to be multiple windows for the user to verify with multiple picture windows (lots of clicking). Sometimes 2-3 windows, sometimes more, despite getting the clicks correct. On another site (same country, same location), there is only 1 picture window that pops up. Can anyone shed any light on why a site would have more verification pics? I tried looking =en but not much info.
Just some follow-up info on the recaptcha score value; how I understand it is the higher the score the safer/better the interaction is. And scores are between 0 and 1.
So setting a threshold of 0 would allow all (or most) users where as 1 would block or challenge more users since it would be harder to achieve such a higher score.
