The practitioner’s view

Treat administrative access as an operational dependency. A policy can look correct while a recovery procedure still depends on an unavailable phone or a single administrator. Review the sign-in paths used by the people who actually operate the environment, including the accounts used during an incident.

A concrete review

Build a small test matrix with normal administration, a new device, and emergency recovery. Record the expected authentication method, the observed result, and who can resolve a failure. Separately inventory automation that signs in as a person and evaluate a workload identity design rather than assuming an interactive process will keep working.

What to take to leadership

Report evidence of successful access and recovery, alongside exceptions with an owner and review date. Enrollment counts alone do not demonstrate that the team can safely operate the platform under pressure.
