How do I save a JWT token in cookie?

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.

How do I save JWT in httpOnly cookie?

Store your access token in memory, and store the refresh token in the cookie: Link to this section

1. Use the httpOnly flag to prevent JavaScript from reading it.
2. Use the secure=true flag so it can only be sent over HTTPS.
3. Use the SameSite=strict flag whenever possible to prevent CSRF.

How do I store JWT tokens in local storage?

First you have to create or Generate Token through Jwt (jsonWebTokens) then either store it in local Storage or through Cookie or through Session. I generally prefer local storage because it is easier to store token in local storage through SET and retrieve it using GET method.

Where should JWT tokens be stored?

Most people tend to store their JWTs in the local storage of the web browser. This tactic leaves your applications open to an attack called XSS. We will only discuss XSS in the JWT context, you can find more about it here.

Is it safe to store access token in cookie?

Local storage is vulnerable because it's easily accessible using JavaScript and an attacker can retrieve your access token and use it later. However, while httpOnly cookies are not accessible using JavaScript, this doesn't mean that by using cookies, you are safe from XSS attacks involving your access token.

Is httpOnly Cookie safe?

All it does is prevent script from reading the cookie. ... HttpOnly won't protect at all if there's any page that reflects the cookie's values back from the server. An XSS could just read the server's response.

Is it safe to store JWT in localStorage?

If you don't have a good reason to put your JWT in local storage, don't! Default to storing it in a cookie (with the secure , httpOnly and sameSite flags set). If you do have a good reason to put it in local storage, go for it!

Can JavaScript set HttpOnly cookie?

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly .

How do I refresh JWT tokens?

The idea is to generate two tokens: an access token (valid for 10 minutes) and a refresh token ,with a longer lifetime. Every time the access token gets expired, the client side app sends a request to generate a new access token, using the refresh token.

What happens when JWT token expires?

That user basically has 5 to 10 minutes to use the JWT before it expires. Once it expires, they'll use their current refresh token to try and get a new JWT. Since the refresh token has been revoked, this operation will fail and they'll be forced to login again.

Are JWT tokens secure?

Using JWTs securely goes beyond verifying their signatures. Apart from the signature, the JWT can contain a few other security-related properties. These properties come in the form of reserved claims that can be included in the body of the JWT. The most crucial security claim is the "exp" claim.

Is JWT the same as OAuth?

JWT and OAuth2 are entirely different and serve different purposes, but they are compatible and can be used together. The OAuth2 protocol does not specify the format of the tokens, therefore JWTs can be incorporated into the usage of OAuth2.
