I'm diving into web development and I'm really enjoying working with Python and React. However, I'm having a hard time understanding how OAuth works. I have some coding experience, mostly in game development, but I have no knowledge about web development concepts. I have a few questions:
1. What is a client secret and why is it important?
2. I've heard about Postman; what is it and do I need it for OAuth?
3. Can someone recommend good tutorials to follow?
4. I haven't set up a web server or a database yet. Can I just use localhost:8000 for OAuth?

Postman basically allows you to test your API endpoints before you go through the process of actually building or hosting your application. It's great for checking if everything is working as expected.
A great place to start understanding OAuth is this overview: https://aaronparecki.com/oauth-2-simplified/. It's a solid, high-level explanation that can help clarify things for you.
Postman is super handy for testing API requests without putting your app online, so you can safely see how things work. And yes, you can absolutely use localhost for OAuth while you're developing.
As for the client secret, if you're using something like Google OAuth, you'll need to sign up for their API. Once you do, they'll give you a client ID and a client secret, which act like a username and password for your app to access their services. You can search for how to get it online, but it’s part of the setup when you register as a developer.
Think of the client secret as a password for your app. You definitely need it if you want to enable features like signing in with Google. But before jumping into that, do you have a basic username/password system in place?
