Hi all, thanks again for the valuable insights, I really appreciate your comments. I realized I’ve overlooked a few topologies, namely that of having granular accounts for different admining purposes/different services (and using different names for them). Also, my IDP (Kanidm) also has a service accounts feature which can be delegated to real human accounts, so I think I should also be looking into that.

It’d be nice to have something like a “second password” for granting temporary privileged access to other apps’ admin commands, but OIDC doesn’t work this way sadly. Lastly I’d also need to consider managing SSH and non-app stuff as well.
