Identity-based Access check-->Signature ID feature

YW Julien but honestly, AES/QES is probably a waste of time & irrelevant overkill. All you would need to do is this part:
1. Email the form to the person (not let them load a URL) AND
2. After they sign/submit, add a random # as an “OpnForm Verified Signature ID" this way you have verified the signature to their identity and done something that looks like a secure hash (no real value besides making ppl feel secure there, lol, which is actually massive value). Will look official. Ppl will then feel comfortable that it was legit and can use OpnForm for all forms including contracts/business agreements. 💯 🚀
