When you send a signature request, you can optionally require the signer to complete a Knowledge-Based Authentication (KBA) identity verification. This process presents the signer with 4–5 challenge questions that must be answered correctly before they can sign the document.
Many regulatory agencies require identity verification when executing official or high-risk documents.
One ID Verification (IDV) Credit is used each time a signer is presented with KBA questions. You can purchase credits as needed or replenish them automatically using a recurring purchase policy.
To avoid interruptions when sending signature requests, you can enable automatic credit purchases.
Automatic credit purchases are processed periodically and may not occur immediately when your balance reaches zero. We recommend maintaining a small credit buffer to ensure signers are not delayed.
