I'm the developer for the website and the client purchased the component.

What do I need to provide to either transfer the license to me or something that enabled me to get support here please...?

HI,

You would need to be logged in as the account holder and that account needs to be an active subscription. I'm not understanding why the client would not give you the details to login so you can get support on their behalf to work on their site.

I just tried logging in using the user's account and it was rejected.

I'm referring also to this post:
