Hi, today I setup a personal account for development using personal email address. Projects and flows are registered under my account. For production deployment, we want multiple people to be able to monitor flow run and access Prefect Cloud UI. What is best practice on setting this up? Should we setup a service account (share email address) and everyone login to same account?

If by other people you mean 3 or less, you can invite them to the tenant because it’s upto 3 free users. If you have more and don’t want to upgrade, yes you’d need to share a log in for the UI

Is flow history owned by the team, not individual? Eg, if we have 3 members, and any one person quit, can we replace with new member while still maintain flow history?

I believe so. Flows are attached to a tenant
