Changes in the 120 days since 13 Jun 2026, when Office Sentry started keeping this tenant's audit log that are worth confirming with the client: domain sign-in (federation) changes, new app secrets and certificates, admin roles granted, and Conditional Access policies deleted or switched off. Failed attempts are left out.

Why it matters: Changes how users of a domain sign in; a rogue federation lets someone sign in as anyone | ||||
