A critical production system is accessed via one shared 'admin' account used by six engineers, with no individual audit trail. How do you fix this?

After a change to your SSO/identity provider configuration, nobody — including admins — can log into any connected system. How do you get back in, and how do you diagnose the actual cause?

A third-party vendor's contract is up for renewal, and their integration still has the broad access it was granted two years ago during initial setup. How do you review and right-size it before renewing?
