SMS & MFA

MFA offers another layer of protection to user login flows, by requiring at least two forms of authentication. There are multiple forms of authentication that can be used in MFA: something you know like a PIN, something you have, such as a cell phone, and something you are such as biometric data. SMS (something you have) is a common way to enable MFA in consumer facing apps for its ease of use and lack of disruption to the user experience.

Auth0 supports a number of different authentication factors, giving businesses and end users the flexibility they need to to authenticate how they want. In addition to our own MFA solutions, we’ve partnered with SMS & MFA providers to improve the user experience while reducing the risk of unauthorized access to your applications.
