Hi @dannywbso,
Welcome to the Auth0 Community!
I understand that you are encountering issues with the Resource Owner Password flow, specifically with the Suspicious request requires verification
error.
This error usually occurs whenever Auth0’s Attack Protection features detect a suspicious authentication, specifically with the Bot Detection feature.
It’s important to be aware that when using the Resource Owner Password Grant flow, the Bot Detection feature should be disabled. This is an inherent limitation with Bot Detection and ROPG.
After disabling Bot Detection, you should be able to authenticate without any errors.
Please let me know if you have any further questions. I would be happy to answer them.
