Frequently asked questions

2345AI Fingerprint Browser is an anti-detect browser, sometimes called a fingerprint browser. Websites recognize visitors by their operating system, screen, fonts, time zone, graphics card and more. 2345AI lets you set these for each browser profile, so every profile looks like a separate device.

A regular browser reveals your computer's real traits, so every account you sign into from that computer carries the same device signature. 2345AI also controls the user agent, Canvas, WebGL, resolution and other parameters, and keeps cookies and cache separate for each profile, so accounts never get linked.

Mostly teams that run many accounts at once: e-commerce sellers with several stores, media buyers with multiple ad accounts, and social media managers handling client accounts. Some people simply want to be tracked less by ads and websites.

Your operating system, browser version, language, time zone, fonts, screen resolution, Canvas and WebGL rendering, and more. Paired with a proxy, it also replaces your real IP address. That goes much further than incognito mode or clearing cookies.

The tool itself is legal. Like a VPN, it only changes your browsing environment. What matters is how you use it: managing your own stores, ad accounts and social profiles is normal; impersonating others, fraud or breaking platform rules is not. Please use it within the law and each platform's terms.

No. Our service doesn't need biometric data and never collects, stores or processes face images, fingerprints or similar data.

No. You sign up and log in with an email or phone number and a password. We recommend turning on two-factor authentication (2FA) for extra security, but that's up to you.

The client runs on Windows and macOS. Team members on different systems can use the same profiles, with data and settings kept in sync.

Download the client, sign up and click New profile. The Free plan includes 2 profiles. Each has its own fingerprint, cookies, local storage and proxy settings. Save common setups as templates or duplicate existing profiles to create many at once.

Yes, that's the main reason people use 2345AI. Put each account in its own profile with its own proxy IP, and even on one computer, platforms see unrelated devices.

The browser doesn't change your network by itself. The IP comes from the proxy you bind to each profile. You can give every profile a different proxy, or use proxies that rotate automatically, which suits scraping, ad monitoring and other work that needs frequent IP changes.

Yes. In a team workspace you share profiles by project and assign permissions. Members use profiles without seeing account passwords, and every action is logged. It works well for marketing teams, ad agencies and e-commerce companies.

It greatly lowers the chance of being linked and tracked, but nothing is 100%. Platforms also look at IP addresses, login behavior and other signals, so use a clean, stable proxy for each profile as well.

No. Platforms also weigh how you behave and transact, and no tool can promise zero bans. 2345AI removes the device and network links between accounts; combined with natural activity and suitable proxies, your accounts will be far more stable.

Every open profile uses some memory and CPU, so the more you run at once, the more your computer needs. A regular laptop or desktop handles a few dozen at a time; for hundreds at once, use a more powerful machine.

Yes. Technical users can edit Canvas, WebGL, fonts, resolution, language and more to match the proxy's region. If you'd rather not, generate a realistic fingerprint with one click.

Yes. An exported profile includes its cookies, sessions, proxy and fingerprint settings, so you can back it up, move it to a new computer or share it with teammates without setting it up again.

Yes. 2345AI offers a local API that works with Selenium, Puppeteer and other automation tools for bulk logins, posting, account testing and more. Keep in mind that very robotic scripts can still be detected by platforms.

Yes. 2345AI supports the MCP protocol, so AI assistants can control browser profiles directly. For example, ask an AI to "open the sign-up pages of four platforms in profiles 1 to 4" and it opens the windows and switches profiles for you.

Yes. Work in one main window and the others repeat the same clicks and typing. It's ideal for doing the same task across many accounts and saves a lot of repetitive work.
