Enter Multi-Factor Authentication
The Entra service MFA, formerlyAzure Multi-Factor Authentication, also known as MFA or 2FA, protects access to your data and applications and meets user demand for a simple sign-in process. It provides strong authentication through a range of simple verification options (phone call, text message, or mobile app notification, and one-time passwords) to allow users to choose their preferred method. It is suitable for on-premises environments and in the cloud. It provides enhanced security when accessing Microsoft Online Services, as well as SaaS applications connected to Azure Active Directory, business applications, and remote access.
Operation
The security of two-factor authentication relies on its layered approach. Compromising multiple authentication factors poses a significant challenge for attackers. Even if an attacker manages to obtain the user’s password, it is useless without the additional authentication method. The principle works by requiring at least two of the following authentication methods:
Something you know
usually a password
Something that is particularly relevant to you
biometrics
Something you have
a trusted device that is not easily duplicated, such as a telephone
Entra Multi-Factor Authentication (MFA) helps secure access to data and applications while keeping management simple for users. MFA It provides additional security by requiring a second form of authentication and offers strong authentication through a range of easy-to-useauthentication methods.
Authentication method
The self-service password reset feature Entra ID / Azure AD and the multi-factor authentication feature may require additional information—known as authentication methods or security information—to verify your identity when you use the associated features.
Administrators can configure, within the policy, the authentication methods available to users for multi-factor authentication and self-service password reset features. Some authentication methods may not be available for all features.
