Session, Cookie, JWT, Token, SSO, and OAuth 2.0 Explained in One Diagram

When you login to a website, your identity needs to be managed. Here is how different solutions work:

- Session - The server stores your identity and gives the browser a session ID cookie. This allows the server to track login state. But cookies don't work well across devices.

- Token - Your identity is encoded into a token sent to the browser. The browser sends this token on future requests for authentication. No server session storage is required. But tokens need encryption/decryption.

- JWT - JSON Web Tokens standardize identity tokens using digital signatures for trust. The signature is contained in the token so no server session is needed.

- SSO - Single Sign On uses a central authentication service. This allows a single login to work across multiple sites.

- OAuth2 - Allows limited access to your data on one site by another site, without giving away passwords.

- QR Code - Encodes a random token into a QR code for mobile login. Scanning the code logs you in without typing a password.

Over to you: QR code logins are gaining popularity. Do you know how it works?

Cookies vs. Tokens

Cookies:
- Traditionally used for session management
- stored client-side
- auto-included in requests
- vulnerable to CSRF

Tokens:
- Commonly JWT
- stateless
- stored in local storage or cookies
- safer against CSRF
- flexible for mobile and SPA
