I have a Angular App at front end and NodeJS as a backend, I have a JWT authentication mechanism setup already at the backend but want to replace that with Auth0 Authentication. I looked into the NodeJS (express) application configuration but it seems it is for complete Web application and not for the API only.
But what I want to do is add an implementation to authorise the user from backend only and not show user the auth0 Login page.
I saw API application as well but did not get much idea. Can you please let me know if I can use auth0 as a backend authentication only and not with front end?
