# 60362: Factor SID invalid or not provided

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when a Verify request that requires `factorSid` or a Factor `{Sid}` does not include a valid Factor SID. Factor SIDs are 34-character identifiers that start with `YF`, and `factorSid` is required when you create a Challenge for a user's Factor.

### Possible causes

* You did not send `factorSid` in a request that creates a Challenge.
* You did not send the Factor `{Sid}` path parameter when you fetched, updated, or otherwise addressed a specific Factor resource.
* The value you sent does not match the expected Factor SID pattern `^YF[0-9a-fA-F]{32}$`.
* You are creating a TOTP verification attempt for a user with multiple factors and did not provide the intended `factorSid`.
* You no longer have the Factor SID that was returned when the Factor was created.

### Possible solutions

* Send `factorSid` in requests that create a Challenge. Send the Factor `{Sid}` path parameter in requests that address a specific Factor resource.
* Verify that the SID starts with `YF` and is exactly 34 characters long before you send the request.
* Use the Factor SID returned when you create the Factor.
* If you do not have the Factor SID, list the Factors for the user's Entity and select the correct one before retrying the request.
* If a user can have multiple TOTP factors, store the intended `factorSid` and send that specific value when you create the Verification Attempt.
