Why do we use JWT token?

Information Exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be sure that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn’t been tampered with.

Are cookies more secure than local storage?

Always assume the worse. While cookies do have a “secure” attribute that you can set, that does not protect the cookie in transit from the application to the browser. So it’s better than nothing but far from secure. Local storage, being a client-side only technology doesn’t know or care if you use HTTP or HTTPS.

Access Token can be read by JavaScript. Cookies, with httpOnly, secure and SameSite=strict flags, are more secure. Access Token and its payload can not be accessed by JavaScript. … With cookies, the access token is still hidden, attackers could only carry out “onsite” attacks.

Should I use session or JWT?

JWT doesn’t have a benefit over using “sessions” per se. JWTs provide a means of maintaining session state on the client instead of doing it on the server. … Moving the session to the client means that you remove the dependency on a server-side session, but it imposes its own set of challenges.

How does server verify JWT token?

The verification flow of json web based token on server side A -> B: Client sends username and password. B: Server checks them against DB records and if they match it creates; first, signature using: base64UrlEncode(header).base64Url(payload), #secret# and then token using: signature.payload.secret. A <- B: Server sends back token to client.More items...•
