60427: Factor ID invalid or not provided

This error occurs when a Verify request that expects a Factor SID does not receive one, or receives a value that does not match the required Factor SID format. Verify Factor SIDs are 34-character identifiers that start with YF. You can see this on endpoints that work with Factors directly and on Challenge requests that require factorSid.

• The request does not include a Factor SID where the endpoint expects it. For example, Create Challenge requires factorSid, while Factor fetch, update, and delete requests require Sid in the path.
• The value in Sid or factorSid is not a valid Factor SID. Verify expects a 34-character SID that starts with YF.
• The value sent in the request is empty, truncated, or otherwise does not match the Factor SID pattern required by Verify.
• In Verify TOTP, the user has multiple factors on the same device and the intended factorSid was not included when creating the verification attempt.

• Send the Factor SID in the correct part of the request. Use Sid for Factor fetch, update, and delete endpoints. Use factorSid when you create a Challenge.
• Validate the SID before you send the request. Use a 34-character Factor SID that matches ^YF[0-9a-fA-F]{32}$.
• If you do not have the Factor SID yet, create the factor first or list the entity's factors and use the sid returned by Verify.
• For Verify TOTP users with multiple factors on the same device, store the correct Factor SID for the selected factor and pass that exact factorSid when you create the Challenge.
