Session token definition
A session token is a unique identifier created when a user logs in to a website or app. It helps the system recognize and manage the user’s activity across multiple pages or requests during the session. Typically stored in a cookie or passed through the URL, the token serves as a key to access session data stored on the server and enables personalized experiences.

Session token purpose
The purpose of a session token is to maintain a seamless user experience. It identifies and authenticates the user, so they don’t need to log in again while navigating through the site. Session tokens help track user activity and provide personalized content.
How does a session token work?
A session token is generated when a user logs in, and is stored in a cookie or URL. As the user navigates the site, the token is sent with each request, allowing the server to recognize the user and maintain their session. This way, the user can stay logged in and access personalized content without re-authenticating.
How are session tokens stored and protected?
Session tokens are typically stored in cookies or local storage on the user’s device. To protect them, they should be flagged as "HttpOnly" and "Secure" to prevent access via JavaScript and ensure they are sent over encrypted connections. Additionally, session tokens should have an expiration time to limit the risk if compromised.
