Microsoft Entra: Domain update for My Account and identity self-service experiences

🚨 The Signal: Microsoft Entra self-service identity experiences (My Account, My Apps, My Access, My Staff) are consolidating under a new unified domain: myaccount.cloud.microsoft. This change streamlines access and supports infrastructure improvements.

The Impact

Network administrators are affected by a potential need to update firewall/proxy allowlists, posing a low security risk if not updated.

• Network Administrators: Risk of service disruption if network allowlists are not updated.
• Security Teams: Need to verify network configurations align with new domain for secure access.

The Action

1. Review existing network, proxy, firewall, and endpoint allowlist configurations for myaccount.microsoft.com, myapps.microsoft.com, myaccess.microsoft.com, and mystaff.microsoft.com.
2. Add myaccount.cloud.microsoft to all relevant network, proxy, firewall, and endpoint allowlists.
3. Validate user access to self-service identity experiences after the change is implemented in late November 2026.
