App-only fallback: when and why

Sometimes you need app-only access for automation or break-glass scenarios. Use it carefully and keep it optional.

Delegated-first works well for admin UI workflows, but automation or restricted tenants may require app-only access.

If you enable app-only, treat secrets as production credentials and rotate them.

Key points

  • Use for automation or specific tenant constraints
  • Store secrets securely and rotate
  • Keep clear separation from delegated mode

This guide is informational. If you’re using Intune features, ensure you have the right tenant permissions and administrator consent where required.
