Passkey Login & Signer Identity Verification

Stronger security with passkey authentication and signer verification, plus powerful new agreement management capabilities and support for four additional languages.

Authentication & Security

Passkey Authentication

• Passwordless Login. Log in securely using passkeys (biometrics, security keys, or device credentials) for a faster, phishing-resistant sign-in experience. Learn about authentication options

Signer Identity Verification

• Email OTP Verification. Require signers to verify their identity via a one-time code sent to their email before accessing an agreement.
• SMS OTP Verification. Add an extra layer of security by requiring a one-time code sent via SMS before signing.
