Store your access token in memory, and store the refresh token in the cookie: Link to this section
- Use the httpOnly flag to prevent JavaScript from reading it.
- Use the secure=true flag so it can only be sent over HTTPS.
- Use the SameSite=strict flag whenever possible to prevent CSRF.
In other words, the cookie doesn’t store any session id. The cookie is merely used as a storage for access token which is passed to the server with every http request and the server then validates the token using the digital signature to ensure that it is not tampered and it is not expired.
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 you set session tokens in PHP?
I am trying to give the session a random token, store that token in a variable, set that token to a hidden input field, and then make sure the two match when the form is submitted. The problem is that the session token that is created doesn’t match the token assigned as a value to the hidden input.
Where do I store my anti CSRF tokens?
I generate a random anti-CSRF token per session and store it in a cookie (with the http_only flag set). Then I add that token to forms (in a hidden input field) and links.
Why do you put CSRF token in session instead of client-side cookie?
If so, why not put the CSRF token in the session instead of a client-side cookie? That’s the normal pattern; it prevents an attacker being able to use their own generated CSRF token value against another user in the case where they have cookie fixation.
Where are tokens stored in a spa backend?
If the SPA backend cannot handle the API calls, the tokens should be stored in the SPA backend but the SPA needs to fetch the tokens from the backend to perform requests to the API. A protocol needs to be established between the backend and the SPA to allow the secure transfer of the token from the backend to the SPA.
