Zero API Keys: Why the Future of Cloud Security Belongs to Managed Identity
And how Azure Container Apps quietly became one of the strongest operational foundations for modern AI services For years, API keys have been the default glue of cloud integrations — copied into files, pasted into CI pipelines, rotated manually, and inevitably leaked somewhere they shouldn’t be. In

"Copied into files, pasted into CI pipelines, rotated manually, and inevitably leaked" is such a precise summary of how these incidents actually happen, it's rarely a sophisticated attack, it's a key sitting somewhere it was never supposed to persist. I was just reading a writeup on this same failure mode in AI-scaffolded apps (Supabase service_role keys ending up in frontend bundles) and it's the identical root cause: a credential that exists as a copyable string will eventually get copied somewhere unsafe. Managed identity sidesteps the whole class of bug by removing the string entirely rather than trying to handle it more carefully. Does Azure Container Apps' managed identity support work cleanly for local dev too, or is that still where teams fall back to a key out of convenience?
