OTP (One-Time Password)

An OTP (one-time password) is a randomly generated temporary code valid for a single session or transaction. In the context of an advanced electronic signature, sending an OTP by email and/or SMS creates a verifiable link between the document and the signatory's identity via their email address or phone number. Certyneo uses Twilio Verify for SMS OTP management on its advanced-level envelopes. Learn more about OTP →
