Should I use JWT or OAuth2?

If you want to provide an API to 3rd party clients, you must use OAuth2 also. OAuth2 is very flexible. JWT implementation is very easy and does not take long to implement. If your application needs this sort of flexibility, you should go with OAuth2.

Is JWT enough to secure API?

JWT is a very modern, simple and secure approach which extends for Json Web Tokens. Json Web Tokens are a stateless solution for authentication. So there is no need to store any session state on the server, which of course is perfect for restful APIs.

Does OAuth 2.0 Use JWT?

JSON Web Token (JWT, RFC 7519) is a way to encode claims in a JSON document that is then signed. JWTs can be used as OAuth 2.0 Bearer Tokens to encode all relevant parts of an access token into the access token itself instead of having to store them in a database.

When should I use JWT tokens?

The tokens are designed to be compact, URL-safe, and usable especially in a web-browser single-sign-on (SSO) context. JWT claims can typically be used to pass identity of authenticated users between an identity provider and a service provider, or any other type of claims as required by business processes.

How does OAuth 2 work in REST API?

OAuth2 is the preferred method of authenticating access to the API. OAuth2 allows authorization without the external application getting the user’s email address or password. Instead, the external application gets a token that authorizes access to the user’s account.

When should you use JWT?

JWTs can be used as an authentication mechanism that does not require a database. The server can avoid using a database because the data store in the JWT sent to the client is safe.

Should you use JWT?

Information Exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be sure that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn’t been tampered with.

What is the difference between JWT and OAuth2?

They are not exclusive. You can use Oauth2 with JWT tokens. The difference between JWT and non JWT tokens is a practical one. JWT tokens require, at most, a one time communication between the resource server and the authorization server at runtime.

What is the difference between OAuth2 and API keys?

The OAuth2 spec and its use of Access Tokens addresses this problem. This is where OAuth2 Access Tokens are a better solution than API Keys. If one is using JWTs as API Keys, then one has to consider how the tokens are issued and used.

How do I pre-authorize a JWT request in API management?

Use the Validate JWT policy to pre-authorize requests in API Management, by validating the access tokens of each incoming request. If a request does not have a valid token, API Management blocks it. For example, add the following policy to the policy section of the Echo API.

What is the difference between JWT and non JWT tokens?

The difference between JWT and non JWT tokens is a practical one. JWT tokens require, at most, a one time communication between the resource server and the authorization server at runtime. The resource server needs to request the authorization server for the public key to decrypt the JWT tokens. This can be done at resource server startup.
