Should I send JWT token in header or body?
The jwt specification recommends (but does not require) sending the access tokens in an authorization header of type Bearer.
Refactor to Store JWT in a Cookie. The first step to switching out to use cookies is to have our API set a cookie in the user’s browser after they successfully log in. Cookies get set in the browser if the response to an HTTP call contains a Set-Cookie header.
Where are JWT tokens stored on server?

- From client side, the good practice is store JWT in cookie, with mode http_only=true, is_secure (so that only send through https), so that JWT is not accessible by javascript. Then, we don’t worry about XSS attach.
- We dont need to store the session on server side.
Should JWT be HttpOnly?
Unless you’re storing way to much data in the token you should not have an issue, but it’s always something to consider. Yes, you can also break a JWT token into multiple cookies, but things start to get more complex.
Are JWT tokens stored on the server?
A JWT needs to be stored in a safe place inside the user’s browser. If you store it inside localStorage, it’s accessible by any script inside your page. This is as bad as it sounds; an XSS attack could give an external attacker access to the token.
Is it safe to store JWT token in Cookie?
Do not store your token in LocalStorage or SessionStorage, because such token can be read from javascript and therefore it is vulnarable to XSS attack. Do not store your token in Cookie.
Which is recommended, pass JWT refresh token on header or body?
For access token, it passed HTTP header per every request. pass refresh token on HTTP header. pass refresh token on HTTP POST body (payload). Which one is recommended? The jwt specification recommends (but does not require) sending the access tokens in an authorization header of type Bearer. But there is no mention of the refresh tokens.
Why are JWTs Cookies signed with a secret key?
Because the token is signed with a secret key, you can verify its signature and implicitly trust what is claimed. Tokens are given to your users after they present some credentials, typically a username and password, but they can also provide API keys, or even tokens from another service.
Why are JWT cookies not protected against XSS?
You are still not protected against XSS because what the attacker can do is inject script that reads your CSRF cookie (which is not HttpOnly) and then make a request to one of your API endpoints using this CSRF token with JWT cookie being sent automatically.
