If you feel a signature request needs an extra layer of security, you can turn on Signer Access Codes. This feature lets you create a unique passcode for the signer to access a document. The code can be something unique or a shared knowledge, like a zip code or the last digits of an employee ID number. The signer will have to enter their access code before viewing the document.
