How do I use JWT authentication with REST API?

Procedure

1. Make sure that the JWT authentication is enabled for REST APIs by setting the value of servlet. jwt. auth.

Which authentication is best for REST API?

Here are some of the best practices for securing your REST API:

• Ensuring Client Security with Third-Party Certificates.
• HTTP Basic Authentication Through Accounts.
• Authentication Through HTTP Digest.
• Authentication Through an API Key.
• Authentication Through a Java Web Token (JWT)
• Authentication Through oAuth.

How do I secure my API with JWT?

How JWT works to secure API

1. The user and the client app first send in the option of sign in.
2. Once verified, your application API will generate a JWT token and then sign in using that API secret key.
3. The API then will give back the token to the respective client application.

Testing Routes. Now the route requires a token header with a valid JWT.
