Interactive demo of QuoteCloud signer verification. Brightline Services sends a Service Agreement to Jordan Lee at Acme Solutions with one-time passcode verification switched on, by email or SMS. On the signer's phone a passcode arrives; you can type it in, or a wrong code to see it refused, then verify and sign. Each event is added to the audit trail, and the certificate of authenticity shows Jordan Lee as passcode verified.

Try it: send, then type the code from the message. Or get it wrong.

A second check, seconds long.

Your client hardly notices. Your records do.

  1. 01

    Switch it on per signer

    Ask for a passcode from the people whose signature matters most.

  2. 02

    A code to their inbox or phone

    Sent by email or text when they open the document to sign.

  3. 03

    Verified, then signed

    The check lands in the audit trail and on the certificate of authenticity.

Verification that holds up later.

The checks you'd want if a signature is ever questioned.

  • By email or by text.

    Send the code by SMS for a second channel, separate from the email that carries the document.

  • Single use, short lived.

    Each passcode works once and expires within minutes.

  • Guesses don't get far.

    Wrong codes are refused and attempts are limited.

  • A Verified badge on the certificate.

    Anyone checking the document later can see who verified, how and when.

    Signature certificate

  • Or an access code you share yourself.

    Set a code and tell your client on a call, so the key never travels with the document.

A forwarded email isn't a signature.

What changes when the signer has to prove it's them.
