# What is a browser profile

A **browser profile** in Gologin is a self-contained virtual browser. It looks and behaves exactly like a real browser installed on a real computer - but it lives inside Gologin and can be created, saved, switched, or deleted in seconds.

Each profile has its own:

* Unique browser [fingerprint](/how-browser-fingerprints-work) (more on this below)
* Cookies and local storage
* Browsing history
* Saved passwords and extensions
* Proxy connection

When you open a profile, websites see it as a completely separate person visiting from a different device. When you close it, everything is saved exactly as you left it.

## Why does this matter? Understanding browser fingerprints

Before diving deeper into profiles, you need to understand one concept: the **browser fingerprint**.

Every time you visit a website, your browser quietly sends dozens of technical signals about your device and setup. Things like:

* What browser you're using and its version
* Your operating system
* Screen resolution
* The fonts installed on your computer
* Your timezone and language
* How your graphics card renders images
* Whether you're using a touchscreen

Websites collect all of these signals and combine them into a unique "fingerprint" that identifies you — even if you clear your cookies, use a VPN, or open an incognito window.

<Note>
  Incognito mode hides your browsing history from other people using the same computer. It does **not** hide your browser fingerprint from websites. Every incognito window still looks exactly like your regular browser to the outside world.
</Note>

This is why simply using multiple accounts in different tabs doesn't work. All those tabs share the same fingerprint, and websites can tell they all belong to the same person.

## How a Gologin profile solves this

When you create a browser profile in Gologin, the app builds a complete fake-but-believable browser identity from scratch.

Gologin generates realistic values for every fingerprint parameter - a plausible screen size, a believable set of fonts, a consistent timezone, a matching user agent string, and so on. All of these values are stored inside the profile and presented to any website you visit while using it.

## How profiles are stored

Gologin stores your profiles in the cloud. This means:

* You can open any profile from any computer where Gologin is installed
* Profiles survive if your local machine crashes or is replaced
* You can share profiles with teammates, who can use the same saved session without needing to log in again

## The difference between a profile and an incognito window

|                                  | Incognito Window | Gologin Profile       |
| -------------------------------- | ---------------- | --------------------- |
| Hides browsing history locally   | ✅                | ✅                     |
| Clears cookies on close          | ✅                | ❌ (cookies are saved) |
| Changes your browser fingerprint | ❌                | ✅                     |
| Changes your IP address          | ❌                | ✅ (with proxy)        |
| Can be saved and reopened        | ❌                | ✅                     |
| Looks like a different device    | ❌                | ✅                     |

Incognito is a privacy tool for your local device. A GoLogin profile is a full identity replacement for the internet.

## Summary

A browser profile in Gologin is a saved virtual browser with its own fingerprint, cookies, and proxy. Opening one makes you look like an entirely different person on a different device to any website you visit. Closing it saves your session so you can return to it anytime. This lets you manage multiple separate online identities from a single computer - cleanly, safely, and without the accounts being linked to each other or back to you.
