Re: Do you have a scalable way of doing that across a a server farm?
There are a number of ways to do it. It mostly depends on how large of a farm, the topology/architecture, and the technologies involved. Centrify or Hashicorp's Vault are two examples that I can vouch for that work well in different environments. Considerations for on-prem only, on-prem/cloud hybrid, container based farms, etc all will change the "best answer" but the answer is definitely out there.
A co-worker just mentioned cyberark when I asked him, so there's a third possible for you.
