Microsoft Entra Certificate-based authentication (CBA) support on iOS and CBA as second factor
Why it matters: Generally available
Microsoft Entra Certificate-Based Authentication (CBA) is now generally available on iOS. Native iOS sign-ins now avoid unnecessary password and MFA prompts, enabling CBA as a supported second factor and allowing it to be prioritized as a system‑preferred MFA method. Users can choose another allowed MFA method if needed, based on tenant policy. More information at Microsoft Entra certificate-based authentication on Apple devices
