Umbraco Forms reCaptcha alternative techniques

Is there a package or helper to create something similar to reCapture without using google services?

Thanks,

Alex

Not sure how similar you're thinking, but here are some ideas:
- Honey Pot This is a common technique where you use a sort of hidden field to trick bots into filling it in, but real users do not fill it in.
- Akismet This is a service that tries to figure out for you whether or not the submission seems spammy.
- Math Captcha You could implement your own captcha that requires a user to solve an equation, like this: https://www.jotform.com/widgets/math-captcha
- NuGet Packages There are some alternatives on NuGet: https://nugetmusthaves.com/Tag/captcha
Here are some additional alternatives: https://www.dtelepathy.com/blog/design/captcha-alternatives-better-ux

You should be able to integrate most of these with Umbraco Forms.

We have created some honey pot-features that we use with a custom workflow.
- meta field that should always be empty, if filed in we assume it’s a robot.
- timer, if the form is posted within 5 (sometimes 10) seconds from page load we ignore this.
This have removed about 99% of the spam and haven’t got any complains from clients about missing posts either.

Another CAPTCHA service to mention is hCaptcha.

It seems it is also available as a addon to Umbraco Forms https://our.umbraco.com/packages/website-utilities/umbracoformsucaptcha/

I haven't tested if it works with latest versions of Umbraco Forms though.

We have also used hCaptcha in the Vendr Reviews package (but the developer is free to replace it by any other CAPTCHA service): https://our.umbraco.com/packages/website-utilities/vendr-reviews/
