Authenticate Users in a Single Page Application with Auth0

Awesome course!

What a surprise, more errors!!!!!!

UnauthorizedError: jwt issuer invalid. expected: https://jak-test.eu.auth0.com

Everything matches up across the Application and API in Auth0. The only thing I can see is that in the API jwtCheck, the audience url has the https prefix, whereas it doesn't in the frontend index.js file.

SOLUTION:

Make sure the jwtCheck in your API.js file uses double quotes ("") rather than single quotes (''), otherwise it is invalid JSON.

Overall review of this course.

I did learn quite a bit in the first few lessons and it was really helpful.

You got really lazy near the end of the course. See my comments on the previous video about how you failed to help your students hook up the front end.

I think its also quite bad that you failed to make a distinction between the first half of the course, which is using JWT's for authorization purposes... using usernames and passwords; and the end of the course using Auth0 which is NOT for authorization purposes. Auth0 only grants permission to the app, it is on the provider to do build an authorization system that sits in front of that.

I feel that point should have been emphasised, otherwise the course just descends into people copy and pasting stuff without really learning.

A little bit more effort and you have a great course here.

Even though I have specified the callback url in the Application Setting on Auth0 platform, I am still gettting this error:

Callback URL mismatch. The URL "http://localhost:8081/index.html" is not in the list of allowed callback URLs.

Please, how can I resolve this?

Have you tried without the index.html?

Yes, I just tried it. The same error.

Awesome course.

Are there good resources for digging farther into some of these security topics (HS256, OpenIDConnect, OIDC Conformant, all the varies types and components of auth)? I’ve been watching some of the cryptography videos on Khan Academy but it’s mostly about theory not nuts and bolts. I know there is google and wikipedia but explainer videos help.

Up and running with JWT , cheers!

Very good introduction to Auth0 and other concepts. Big thanks!!!
