I'm creating a React Application that will be used in production for around 12-20 clients starting out, but it may grow in use in the future. This application will need to be maintained by 2 developers without much back-end experience.
We want this to be secure, scalable, and as easy as possible to maintain. In the past we've experimented with creating our own solution using a Node Server serving JWTokens which keep the authentication status throughout the app using Redux. This code gets pretty cumbersome and is difficult to understand for me and our 2 front end developers. We've also experimented with AWS Amplify, but found it somewhat limiting and constrictive.
I just wanted to see what other developers are using for Authentication systems in their production-level apps. Security is pretty important to this application as well, as it will be storing sensitive user data. Any help would be appreciated.
