TPMAPI_E_AUTHORIZATION_FAILED
TPMAPI_E_AUTHORIZATION_FAILED is a Windows TPM API result. It indicates that the authorization data supplied for the TPM operation does not validate for the target object or policy.
What to check for TPMAPI_E_AUTHORIZATION_FAILED
- Verify that the correct authorization value, session, and target object are used together.
- Check whether the object was cleared, reprovisioned, migrated, or replaced after credentials were saved.
- Avoid logging authorization secrets while diagnosing the failed request.
Microsoft documentation for TPMAPI error codes
Diagnostic interpretation
This result has the HRESULT value 0x80290109. AllStat records the condition as “The specified authorization information was invalid.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the tpmapi / authorization operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
Retry and recovery
Treat TPMAPI_E_AUTHORIZATION_FAILED as a checkpoint, not as a request to loop. Retry only after evidence shows that the rejecting state has changed, and verify the same scenario end to end.
