How to translate captcha and signature fields

Hi guys, I have forms for our school that are in English and translated to French, but there is a couple of areas that do not translate and we cannot find where to change them, they are the Signature widget and Recaptcha, please that a look at the page, please let us know if you can help us, thank you.

I am afraid that this is not currently possible to translate those widget fields.

You may consider using a standard Captcha field and a Smooth Signature widget field instead. They should be translatable.

If you need any further assistance, please let us know.
