## Session

Also called browser session, login session, session ID, session hijacking

Definition

A session is the period during which a website recognises you as the same visitor, usually because the browser sends back a cookie holding a random session ID that the server links to your login.

Last updated 7 November 2026

### How it works

When you sign in, the server creates a session record and gives the browser an identifier for it, normally in a cookie. Each later request carries the cookie, and the server looks the session up instead of asking for your password again. A session ends when it expires, when you sign out, or when the server decides to end it, for example after a password change or when something about the session looks wrong.

Many sites watch for exactly that. A session ID that suddenly arrives from a different country, a different device or a different browser is a classic sign that someone copied it, and sites respond with a new sign-in or a verification step.

### Why it matters when you run several accounts

A stable session is what keeps an account signed in without constant verification. That means the same profile, the same device values and a stable network location from one visit to the next. Two people driving the same session at once, or a session hopping between proxies, is what breaks it.

### How SoftGlaze Browser handles it

A profile’s cookies and storage stay in its own folder between launches, so its logins persist across restarts, and its cookies stay put when a rotation pool changes its proxy (whether a site accepts the session from a new address is the site’s decision). A running profile is locked to the member who opened it, so two people can’t drive the same session by accident, and launching a profile that is already open reuses the running browser instead of opening a second one on the same data.

-   [Cookies](https://browser.softglaze.com/glossary/cookies) Cookies are small named values that a website asks the browser to store and send back with later requests, which is how a site remembers a login, a basket or a preference between page loads.
-   [Sticky session](https://browser.softglaze.com/glossary/sticky-session) A sticky session is a proxy setting that keeps you on the same exit IP address for a period of time or until you ask for a new one, instead of changing it on every request.
-   [Local storage](https://browser.softglaze.com/glossary/local-storage) Local storage is the space a browser gives each website to keep data on your device between visits, most simply through the localStorage interface, where values stay until the site or the user removes them.
-   [Two-factor authentication (2FA)](https://browser.softglaze.com/glossary/two-factor-authentication) Two-factor authentication (2FA) is a sign-in that needs two different kinds of proof, typically a password plus a one-time code from an authenticator app, a text message or a security key.
-   [Browser profile](https://browser.softglaze.com/glossary/browser-profile) A browser profile is a self-contained set of browser data (cookies, local storage, history, saved logins, extensions and settings) kept in its own folder, so two profiles on one computer don't see each other's sessions.
