Secure access to resources with multifactor authentication

Help protect your organization against breaches due to lost or stolen credentials with strong authentication. Secure any app with just one step.

Security is complex. We can help you simplify it.

Managing multiple standalone security solutions can get complicated. Learn how consolidating security vendors can help you reduce costs by up to 60 percent, close coverage gaps, and prevent even the most sophisticated attacks.

What is multifactor authentication (MFA)?

Multifactor authentication (MFA) adds a layer of protection to the sign-in process. When accessing accounts or apps, users provide additional identity verification, such as scanning a fingerprint or entering a code received by phone.

Why use multifactor authentication (MFA)?

It’s more secure than passwords

In most identity attacks, it doesn’t matter how long or complex your passwords are.

Some types of multifactor authentication (MFA) are stronger than others

Make sure your credentials for high-risk accounts are resistant to phishing and channel jacking.

Passwords are making you vulnerable

Protect your business from common identity attacks with one simple action.

Multifactor authentication in Azure AD

Azure AD offers a broad range of flexible multifactor authentication (MFA) methods—such as texts, calls, biometrics, and one-time passcodes—to meet the unique needs of your organization and help keep your users protected.

Choose the right technology

Azure AD multifactor authentication (MFA) works by requiring two or more verification methods.

Microsoft Authenticator

Approve sign-ins from a mobile app using push notifications, biometrics, or one-time passcodes. Augment or replace passwords with two-step verification and boost the security of your accounts from your mobile device.1

Windows Hello for Business

Replace your passwords with strong two-factor authentication (2FA) on Windows 10 devices. Use a credential tied to your device along with a PIN, a fingerprint, or facial recognition to protect your accounts.


FIDO2 security keys

Sign in without a username or password using an external USB, near-field communication (NFC), or other external security key that supports Fast Identity Online (FIDO) standards in place of a password.

Hardware tokens

Automatically generate a one-time password (OTP) based on open authentication (OATH) standards from a physical device.

Software tokens

Use the Microsoft Authenticator app or other apps to generate an OATH verification code as a second form of authentication.

SMS and voice

Receive a code on your mobile phone via SMS or voice call to augment your password security.
