Learn how to implement MFA and step-up authentication across your application using Authsignal actions.
Actions are the foundation for implementing multi-factor authentication (MFA) and step-up authentication in your application. By tracking specific user activities as actions, you can apply contextual security policies that challenge users when needed.
The most common MFA scenario is requiring additional authentication after a user’s primary credentials (username and password) have been validated.Here’s how the flow works with Authsignal:
Step-up authentication challenges users when they perform sensitive operations, even if they’re already logged in. This is ideal for high-risk actions like financial transactions, account settings changes, or data exports.
