That's the one for sure thing I'd never do.

Thank you @robnotyou I tried assigning the role but they still couldn't generate a certificate. I then contacted Support and was told with my type of account (individual) I had to generate the certificate myself. Now I'm wondering how, like if I need to do that from a Mac, and how to send that certificate to the developer. I appreciate your response.

I looked back through the email chain with support and this is what I found "Individuals enrolled in the Apple Developer Program can give additional users access to their content in App Store Connect, however, these users will only receive access to App Store Connect and are not considered part of the team in the Apple Developer Program. They will not receive access to other membership resources or benefits. As the Account Holder, you may create these assets, and then export signing certificates and provisioning profiles for your developers." So, I guess my next question is, do I have to do that from a Mac computer, and which of the signing certificates, and or provisioning profiles, do I need to generate and send the developer?

The developer said they could generate certificates if I could share my screen on "anydesk". Is that something that is safe?

Thanks
