First, what is a JSON Web Token, or JWT (pronounced “jot”)? In a nutshell, a JWT is a secure and trustworthy standard for token authentication. JWTs allow you to digitally sign information (referred to as claims) with a signature and can be verified at a later time with a secret signing key.

['The application or client requests authorization to the authorization server. ... ', 'When the authorization is granted, the authorization server returns an access token to the application.', 'The application uses the access token to access a protected resource (like an API).']

JWTs can be either signed, encrypted or both. If a token is signed, but not encrypted, everyone can read its contents, but when you don't know the private key, you can't change it.

JWT can be used for many things, among those are bearer tokens, i.e. a piece of information that you can present to some service that by virtue of you having it (you being the "bearer") grants you access to something.

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 (which is as bad as it sounds, as an XSS attack can let an external attacker get access to the token). Don't store it in local storage (or session storage).

CSRF token is tied to a non-session cookie The attacker can log in to the application using their own account, obtain a valid token and associated cookie, leverage the cookie-setting behavior to place their cookie into the victim's browser, and feed their token to the victim in their CSRF attack.

Anti-CSRF tokens (or simply CSRF tokens) are unique values used in web applications to prevent Cross-Site Request Forgery attacks (CSRF/XSRF). CSRF attacks are client-side attacks that can be used to redirect users to a malicious website, steal sensitive information, or execute other actions within a user's session.

By default, access tokens are valid for 60 days and programmatic refresh tokens are valid for a year. The member must reauthorize your application when refresh tokens expire.

Check the signature The last segment of a JWT is the Signature, which is used to verify that the token was signed by the sender and not altered in any way. The Signature is created using the Header and Payload segments, a signing algorithm, and a secret or public key (depending on the chosen signing algorithm).

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed.

['The client sends a "client hello" message. ... ', 'The server responds with a "server hello" message. ... ', "The client verifies the server's SSL certificate from CA (Certificate Authority) and authenticates the server. ... ", "The client creates a session key, encrypts it with the server's public key and sends it to the server."]

Let's start with the biggest reason why OAuth isn't authentication: access tokens are not intended for the client application. When an authorization server issues an access token, the intended audience is the protected resource. ... It's down to the protected resource to understand and validate the token.

IsAuthenticated is always True. Even simple HTTP request without cookies turns out to be authenticated.

If the certificate is expired, the user's browser has no way to validate the server. That means it can't definitively tell you if the website presenting this certificate is its rightful owner. That's going to cause a browser error that says your connection is not secure.

So, you basically have your user id registered to the server. Both the server and client use this id to generate a new token after some specific time interval. During login, the server just has to check if both the generated values are same, if yes, then you are logged in.
