Cookie

A Session Token is an encrypted credential generated by a web application after a user logs in, stored in the browser's Cookie, used to verify the user's identity without requiring repeated password entry.

Mainstream browsers are gradually phasing out third-party cookies and introducing stricter privacy protection mechanisms.

Traditional attribution relies on cookies, device identifiers, and user behavior sequences, assuming by default that "one real-person account corresponds to one explainable decision path."

APX provides a path for requesting user approval to copy cookies for a specific domain into the APX browser profile; this operation can only be performed by a human, and at runtime the origin name and number of domains can be checked, but cookie values remain on the desktop side.

A session token is a temporary credential issued by the server after a user successfully logs in, usually stored on the client as a Cookie or JWT, with an expiration period after which re-authentication is required.

Even after clearing all cookies and using incognito mode, fingerprinting can still re-associate users.

Setting a cookie expiration period to 20 years is practically equivalent to never expiring.

Overly long cookies are often the result of unreviewed default settings from analytics tools or CDNs, rather than the product of explicit design intent.

The longer a tracking identifier persists, the more easily it can be combined with other datasets to re-identify individuals.

Session cookies expire when the browser is closed, while persistent cookies are typically set to last anywhere from a few days to one year.

Cookies and tokens are the core credentials by which websites identify logged-in users, and holders can fully simulate a user's logged-in state until the token expires.

Unlike passwords, Cookie/Token leaks typically do not trigger secondary verification prompts such as 'unknown device,' making them harder for account holders to detect immediately.

The user impersonation approach recommended by most web frameworks is to swap cookies, i.e., replacing the current session cookie with the target user's session cookie

Cookies are credential carriers automatically managed by the browser and automatically attached to requests

In the cookie-swap approach, the save-and-restore-original-credentials process upon exiting impersonation itself constitutes an attack surface that may lead to session confusion or privilege escalation.

Browser cookies are small text credentials issued by the server to the client, used to maintain session state on top of the stateless HTTP protocol.

Data in localStorage is not automatically sent to the server with each HTTP request, and persists even after closing the browser or restarting the computer.

Unlike cookies, data in localStorage is not automatically sent to the server with HTTP requests, and the data persists even after closing and reopening the browser.
