Summary:
Starting February 3rd, 2025, Microsoft will enforce multi-factor authentication for all users accessing the Microsoft 365 admin center. Users and global admins must set up MFA before this date, with resources available for guidance and an option to postpone enforcement if unprepared.

Details:
Updated January 7, 2025: As a reminder, starting February 3rd, 2025, Microsoft will begin requiring all users to use multi-factor authentication when signing into the Microsoft 365 admin center. Please see below for details and actions you can take to be ready for this change. For more information and FAQs, visit the blog post here.
Implementing multi-factor authentication (MFA) in the Microsoft 365 admin center significantly reduces the risk of account compromise, prevents unauthorized access, and safeguards sensitive data. By adding an extra layer of protection beyond standard username and password authentication, MFA makes it harder for attackers to steal data and prevents unauthorized access from phishing, credential stuffing, brute force, or password reuse attacks. As part of our ongoing commitment to advancing cybersecurity across our company and products, starting February 3rd, 2025, Microsoft will begin requiring all users to use MFA when signing into the Microsoft 365 admin center. This requirement will be rolled out in phases at the tenant level over the coming weeks.
Take action now:
Global admins: To set up MFA in your organization now, visit the MFA setup guide at aka.ms/MFAWizard or refer to Set up multifactor authentication for Microsoft 365.
Users accessing the Microsoft 365 admin center: Check your verification methods and add one if needed by going to aka.ms/mfasetup.
