What protocol does JWT use?
JWT relies on other JSON-based standards: JSON Web Signature and JSON Web Encryption.
How do I authenticate a user on JWT?
To authenticate a user, a client application must send a JSON Web Token (JWT) in the authorization header of the HTTP request to your backend API. API Gateway validates the token on behalf of your API, so you don’t have to add any code in your API to process the authentication.
What type of authentication is JWT?
JSON Web Token
What is JWT Authentication? JSON Web Token (JWT) is a JSON encoded representation of a claim(s) that can be transferred between two parties. The claim is digitally signed by the issuer of the token, and the party receiving this token can later use this digital signature to prove the ownership on the claim.
What is secret in JWT?
JWT is created with a secret key and that secret key is private to you which means you will never reveal that to the public or inject inside the JWT token. When you receive a JWT from the client, you can verify that JWT with this that secret key stored on the server.
When do you use JWT for API authentication?
Using JWT for API authentication A very common use for JWT — and perhaps the only good one — is as an API authentication mechanism. JWT technology is so popular and widely used that Google uses it to let you authenticate to its APIs. The idea is simple: you get a secret token from the service when you set up the API:

Is it safe to use JWT as session token?
On the other hand, you should not use JWTs as session tokens by default. For one thing, JWT has a wide range of features and a large scope, which increases the potential for mistakes, either by library authors or users.
What do we use JWT for in SEC?
HMAC – Hash with a secret key to generate signatures. So, since JWT is about statelessness, when you pass data from here to there and back, it’s all in JWT. Instead of the traditional session on the server, you pass the data in the JWT so you don’t need to store data on the server. What do we use JWT for? We use it for authentication.
