Couldn't you use an Azure webapp? It has FTP and user management, though not as granular as this. You should be able to use IAM to only allow the user access to that one web app and they can set their own username/password. Not quite as simple as sending out creds from one interface, but it's an option. Not sure how many users you have, obviously if you had tons and tons of users it would become a choir, but if it's just a few users I'm thinking a webapp could handle that. Alternatively, if trusted users enough, you could use an Azure blob and use CloudBerry. That one is probably not HIPPA compliant though. I don't even know if this new AWS SFTP plan is HIPPA compliant, don't you have to have a log of file check in/outs? And user login logs?
