Why this book

When MFA, Conditional Access or federation fails, someone still has to get into the tenant. This guide covers emergency access accounts end to end: how many to keep, how to protect them, how to exclude them safely, and how to know the moment one is used.

Who it's for

  • Administrators responsible for tenant-wide sign-in policies
  • Security teams writing an incident and recovery plan for Entra ID
  • Anyone who has ever locked themselves out of Conditional Access

What's inside

  1. Why every tenant needs emergency access, and what it must survive
  2. Designing the accounts: how many, cloud-only, and how they authenticate
  3. Excluding them from policy without creating a gap
  4. Storing credentials so they are available, but never casually
  5. Alerting on every sign-in and testing the accounts on a schedule
  6. The runbook: who uses them, when, and what happens after
