Implementing a Multi-Factor Authentication in React Using Auth0 and AWS Amplify

I wrote an article on the AWS Blog about Auth0 identity management capabilities and AWS Amplify.

In particular, I've explored how to integrate a React single SPA with Auth0 to provide user identity and multi-factor authentication (MFA), and AWS Amplify to build, deploy, and host a single SPA on the AWS Cloud. I've also explored what MFA is, why it is needed, and how to easily one can implement it via Auth0 Rules.
