Entra CBA Moves from Last to Third in System-Preferred MFA Order to Improve Reliability and User Experience! When you sign in, the system checks the ways you can verify your identity, like an app, text code, or certificate. It suggests the safest method first, but you can choose another one if you want. The order can change as security improves. If your organisation requires a specific method, those rules come first. The goal is to make sign-ins both safe and easy for users.

Entra CBA Moves from Last to Third in System-Preferred MFA Order to Improve Reliability and User Experience
System-preferred MFA helps users to sign in using the most secure method they have registered, like using an app instead of SMS. It improves security and reduces the use of less safe methods. Users can still choose another method, but the system suggests the safest one first.
This setting is managed by Microsoft and is usually enabled by default. Administrators can turn it off or exclude certain users if needed. Once enabled, the system automatically decides the most secure method for each sign-in, so users don’t need to set a default.

| Certificate Based Authentication (CBA) was previously placed last in the system preferred MFA order due to known issues with CBA and system preferred MFA. Now that those issues are resolved, starting March 18th, 2026, Certificate-based authentication(CBA) will move to the third position in the authentication order. Once the rollout is complete, we will update the ordering of methods in the documentation. |

Microsoft Entra Certificate-Based Authentication (CBA) – Secure, Phishing-Resistant Sign-In with X.509 Certificates
Microsoft Entra Certificate-Based Authentication (CBA) lets users sign in to applications and browsers using X.509 certificates directly through Microsoft Entra ID. This method is phishing-resistant and works with your organisation’s public key infrastructure (PKI).
Previously, organisations had to use federated CBA with AD FS to authenticate certificate-based sign-ins. With Microsoft Entra CBA, users can authenticate directly against Entra ID, which simplifies the setup and reduces costs by removing the need for federated AD FS. CBA is a secure, certificate-based way to sign in without needing extra federation servers.
