What are the differences between OAuth and JWT in Angular applications?

What are the differences between OAuth and JWT in Angular applications?

OAuth is an authorization framework, while JWT (JSON Web Token) is a token format. OAuth allows third-party services to exchange information without sharing credentials, whereas JWT is used to securely transmit information between parties as a JSON object.

Can you explain how to implement OAuth in an Angular app?

To implement OAuth in an Angular app, you typically use a library like angular-oauth2-oidc. You'll need to configure the OAuth service with your client ID, redirect URI, and scopes, then handle the authentication flow.

What are the security benefits of using JWT?

JWTs are stateless and can be verified without a database lookup, reducing server load. They also allow for expiration times, which enhances security by limiting the lifespan of tokens.

Are there any drawbacks to using JWT?

Yes, JWTs can become large if they contain too much data, and if a token is compromised, it can be used until it expires. Additionally, revoking tokens can be challenging since they are stateless.
