The additional OTP verification step prevents administrators from circumventing approval workflows via credential resets or authentication endpoint changes. Approvers receive six-digit codes when casting votes through the Approval Portal and must enter the code within a 10-minute window to complete their approvals, with up to three retry attempts allowed.
While this security enhancement adds authentication rigor to protected operations, user experience effects and potential workflow delays have not been independently analyzed. The feature is available across all AWS Regions offering Multi-party Approval with no extra charges.
