If the code delivery type is set to offline, the document owner must share the access code with the recipient manually.

The recipient must enter the OTP and click Proceed to Document, and will then be directed to the document viewer to sign the documents.

If the OTP is entered incorrectly three times in a row, the recipient will immediately lose access to the documents. The recipient will need to ask the owner to restore their access.
If the recipient did not receive the OTP or forgot the code, the recipient can click the Resend code option below the Verify button.
