Adaptive MFA

Adaptive MFA

Over 80% of data breaches involve lost or stolen credentials. While MFA can block 99.9% of account hacking attacks, many companies shy away from traditional MFA due to compromises to the user experience.

Auth0’s Adaptive MFA is based on various types of behavioral signals, meaning the MFA step is only presented when deemed risky. This preserves the experience for the majority of users, while maintaining a strong security posture.

Defense In Depth

Over 50% of users admit to reusing the same password for multiple services, so even if your authentication system follows all the best practices, a compromised account elsewhere can lead to unauthorized access in your system.

With multi-factor authentication, even if the user's password is compromised- the bad guys can't get in.

White-label multi-factor

Use the Guardian Mobile SDKs — available for iOS and Android — to build your own white-label multifactor authentication application with complete control over the branding and look-and-feel.


Users don’t need the Guardian app or even a smartphone to benefit from the protection of our advanced MFA features. Any phone capable of receiving SMS text messages can be used to receive one-time codes.


For whenever a user cannot access their mobile device for authentication, they can choose to use their verified email to complete authentication.


Secure authentication shouldn’t be limited only to those users with SMS or email availability. As an alternative, Auth0 offers Voice MFA. Users can choose to have their one-time code for MFA delivered via phone call in addition to SMS.

Smartphone with Microsoft Authenticator app


Our MFA solution works everywhere. Use the Guardian iOS or Android app to receive push notifications, get one-time codes delivered via SMS or connect with a third party token generation app such as Google Authenticator.

How It Works

Choose the multi-factor authentication method that is right for your users – SMS, third-party authenticators, and more. Or choose Guardian and let your users authenticate with the tap of a button.
