Lock documents behind a one-time access code
Require a one-time passcode by email or SMS before a recipient can open a document — so sensitive agreements only reach the intended signer.
What you get
- Email or SMS one-time passcode before opening
- Per-signer, locked signing links
- AES-256 + TLS encryption in transit and at rest
- Recorded in the audit trail
How it works
- Turn on the access code — Enable OTP on the document or in signing defaults.
- Recipient requests a code — They get a 6-digit code by email or SMS.
- Verified, then signs — Only after entering the code does the document open.
Frequently asked questions
How does OTP signing work?
Before opening the document, the recipient enters a 6-digit code sent to their email or phone, confirming they are the intended signer.
Is the document encrypted?
Yes — AES-256 at rest and TLS in transit, the same standards used by major banks.
