That's exactly what I've been through in most of the debugging process. It's like doing an unsolvable math quiz. But the desire of solving it won't let me go easily. Btw have you tried to "catch" all Pokémon with your pokedex and promote yourself to a Pokémon Master?

Victoria Lo That's so cool. Thanks for the explanation. Now I see what auth0 is about. 😁

Thanks. And also thanks for the reply. So by reading your code and the description. Can I conclude that we can outsource the authentication part to the auth0 easily?

Very detailed tutorial. I just finished my full-stack course. And now I can finally understand what is this post talking about. Haha. I have a brief idea how authentication works now. And experienced some other authentication methods too. But do not know what auth0 is about. All I know it is a kind of oauth. May I know what is auth0 in brief description and What are the differences between it and google-oauth / facebook-oauth?
