Important update for CIOs and IT leaders managing identity and access:
From February 2026, Microsoft Entra will automatically block authentication on rooted or jailbroken mobile devices when using the Microsoft Authenticator app.
This means credentials issued on compromised devices will no longer be valid, marking a significant advancement in strengthening zero-trust security and protecting organisational identities at the endpoint.
Key Actions for IT Teams
- No admin action is required as this update will be secure by default.
- Review your MDM and BYOD frameworks to ensure compliance.
- Communicate early with users who rely on Authenticator for MFA to minimise disruption.
Microsoft continues to strike the right balance between usability and security, reinforcing Entra’s position as a leader in identity governance and access protection.
