Step-Up MFA API Reference

The Step-Up MFA APIs can be called from your backend using your PropelAuth API Key. These APIs are not required for your users to login with MFA and are instead to be used when you want to require a user to verify their MFA for a specific action within your application.

Check out the Step-Up MFA documentation for more information on how to use these APIs.
