Choose a signer authentication method that fits into your workflow
SMS verification
Send an SMS with a personalized message and unique password. Signers will be required to enter the password you shared with them via SMS to access a signing session inside your application.
Phone call verification
Provide a relevant phone number and your signer will receive a phone call prior to gaining access to an embedded signing session. The signer passes authentication once they pick up the phone call.
Password protection
Create a secret password for accessing an embedded signing session and share it discreetly with your signers. They will have to enter the password to complete the verification and access your document.
