JSON Web Tokens (JWTs) are crucial for securing data transmission in single-page applications (SPAs), but they come with security risks such as cross-site scripting (XSS) and cross-site request forgery (CSRF). Secure storage methods include using HttpOnly cookies with the Secure flag, encrypting JWTs before client-side storage, and employing server-side session management. Advanced practices like using web workers and Content Security Policies (CSPs) further enhance security. Continuous security audits and updates are necessary to maintain a secure SPA.

Secure JWT Storage: Best Practices

I thought JWT mustn’t be stored. Otherwise it becomes session based. Or am I mistaken?

for me I prefer to keep jwts on the server side (Server-side session management), no need to send it to the client, you manage everything from the backend

Very good informations!! Thanks!!

Great content! I am using jwt for my node application and i am storing the token on the browser local storage, how can i set the token to null after some time of inactivity?

Very nice information, thank you so much
