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.

What do you like best?

Easy to use and turn around times are great. I can get my client's signatures on documents in a matter of minutes. Previously to using airSlate SignNow, I had to wait for the clients to print out documents to sign and scan back to me. This was an issue because not everyone has a printer at home. airSlate SignNow has eliminated that issue. The time savings and turnaround time are by far the best feature. It's super easy to learn and use airSlate SignNow. I love how I can make templates and just make a copy for quick reference
