Effective February 3, 2025, Microsoft will require multifactor authentication (MFA) for all user accounts accessing the Microsoft 365 admin center. This change aims to enhance security and protect user accounts from unauthorized access. The rollout will occur in phases, and administrators will receive notifications approximately 30 days before enforcement begins.
What is Multifactor Authentication?
Multifactor authentication (MFA) is a security process that requires users to provide two or more verification methods to access their accounts. These methods can include:
- Something you know: Password or PIN
- Something you have: Mobile device or security key
- Something you are: Fingerprint or facial recognition
MFA significantly reduces the risk of unauthorized access, even if a password is compromised.
Key Features
- Enhanced Security: MFA adds an extra layer of protection to user accounts.
- Reduced Risk: Research shows that MFA can block over 99% of account compromise attempts.
- User Control: Administrators can set up and manage MFA settings easily through the Microsoft 365 admin center.
Licensing
All users accessing the Microsoft 365 admin center will need to comply with the MFA requirement. Organizations that already have MFA policies in place will not need to make additional changes.
