identity.
Practical identity guidance for sign-in, MFA, Conditional Access, SSO, device identity and application access.
Prove the sign-in
Use sign-in logs, authentication details, correlation IDs and token context to establish what actually failed.
Trace the decision
Evaluate user, application, device, location, risk and authentication-strength conditions before changing policy.
Control the identity
Understand users, groups, devices, service principals, roles and application identities as separate security boundaries.
Verify every request
Use identity, device and risk signals to make access decisions with explicit evidence and least privilege.

Entra diagnostic model
Identity → Application → Conditions → Policy → Authentication → Authorization → Verify. Do not solve a policy problem by weakening a control you have not yet proven responsible.
