Another method you might consider implementing would be identity verification via SMS code. I've experienced this with docusign: https://support.docusign.com/s/document-item?language=en_US&...

It requires you to know the phone number of the signer, but for important stuff you typically do.

Yep, support for SMS verification will be added eventually with ability to bring own Twilio credentials when self-hosting it.
