Benefits of MFA

Free and easy

Create a free account and enable multi-factor authentication (MFA) to prompt users for additional verification.

Protect your identities

Enable MFA (or 2FA) to ensure your accounts are up to 99.9% less likely to be compromised.

Use across applications

Provide users secure, seamless access to all their apps with single sign-on from any location or device.

What is MFA?

Your passwords can be easily compromised. MFA immediately increases your account security by requiring multiple forms of verification to prove your identity when signing into an application.

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 phone.

Windows Hello for Business

Replace your passwords with strong two-factor authentication (2FA) on Windows 10 PCs. 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 third-party 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 the security of your passwords.

Why make MFA a priority?

Learn why your password doesn’t matter, but MFA does. Alex Weinert, Director of Identity Security at Microsoft, discusses basic measures you can take to protect your organization against identity attacks.
