This walks you through adding multi-factor authentication to your Auth0 setup, covering everything from basic TOTP and SMS codes to WebAuthn passkeys and step-up authentication for sensitive operations. The guide is split across multiple reference files with framework-specific examples for React, Next.js, Vue, and Angular, plus backend validation patterns. What's useful here is the focus on step-up auth using the acr_values parameter, so you can require MFA only when users hit sensitive actions like payments or settings changes rather than forcing it on every login. Good fit if you're implementing compliance requirements or just want to add an extra security layer without annoying users constantly.
