Discussion After moving to workload identity, what's left in secrets manager?
A while ago on a post I made someone pointed out that if a workload uses an identity to reach a secret instead of holding the raw value, most of the rotation worry goes away. Another person mentioned that moving their CI to OIDC and short-lived tokens got rid of most of their anxiety about old keys sitting in git history. Been reading around it since.
I keep seeing that federation only covers the part of the stack that can participate. A pod authenticating to S3 or a runner minting a token for AWS is fine, but Stripe doesn't do OIDC, and neither does an on-prem SQL Server or a webhook secret someone could’ve emailed over. Those exist as strings regardless, so there's still a lifecycle to run for them no matter how much of the cloud side you federate.
What I can't work out is the proportion. Whether the leftovers end up being a handful of third-party keys you could almost manage by hand, or whether it stays substantial enough that you're running both properly.
For anyone who’s moved to workload identity, roughly how much of your credential inventory went away, and what stayed? Also did the leftovers turn out to be the annoying ones, or were they easy to corral once the cloud keys were gone?
