Microsoft will enforce mandatory multi-factor authentication (MFA) for the Microsoft 365 admin center starting February 2025. All logins must pass an MFA challenge to enhance account security and prevent unauthorized access. This is a significant security enhancement aimed at mitigating the risk of account hijacking. The enforcement of MFA is a crucial step in bolstering the security posture of Microsoft 365 environments. It addresses the growing threat of credential theft and unauthorized access to sensitive administrative functions. By requiring MFA, Microsoft significantly raises the bar for attackers, making it harder for them to gain control of admin accounts.
