You need an anti-detect browser when you run many accounts from one computer and don't want websites to link them. It hides your device's characteristics, but it doesn't change your IP address by itself — that is what a proxy is for. Here is how an anti-detect browser works, why it is useless without a proxy, and how to pair the two properly.
What an anti-detect browser is
It is a browser in which you can create many separate profiles. To websites, each profile looks like a separate device:
- its own digital fingerprint — browser and OS version, screen resolution, fonts, graphics card, Canvas and WebGL fingerprints, language and time zone;
- its own cookies and storage — profiles can't see each other's data, as if they were different computers;
- its own proxy — every profile has its own IP address.
Popular anti-detect browsers include Dolphin Anty, AdsPower, Octo Browser, GoLogin, Multilogin and Incogniton. They are used by social media managers, affiliate marketers, online shops and testers — anyone who needs several accounts on one platform or wants to see a website through the eyes of different users.
Why an anti-detect browser needs a proxy
Websites link accounts not only by browser fingerprint but also by IP address. If ten profiles with different fingerprints log in from one IP, to the website it is still one person — and the anti-detect browser has hidden nothing. Hence the main rule: one profile, one proxy.
The IP address also gives away your location. If a profile's fingerprint says "Germany, Berlin time zone, German language" while the IP is from another country, that mismatch is suspicious in itself. The proxy's country, the profile's time zone and its language should all match.
Which proxy to choose for an anti-detect browser
| Task | Proxy |
|---|---|
| Accounts on IPv6 websites — Google, YouTube, Instagram, Facebook, Telegram — each needing its own permanent IP | Per-IP IPv6 proxies: the address is yours for the whole term |
| Ad accounts, registering and warming up accounts, platforms with strict checks | Mobile proxies: many real subscribers sit behind a mobile IP, so such addresses are blocked more cautiously |
| A website without IPv6 | Mobile proxies |
Accounts need stability: logging in to the same account from a new address every time looks suspicious. That is why accounts get proxies with a permanent IP rather than traffic-based proxies, whose addresses change with each new generation.
Before buying IPv6 proxies, make sure the websites you need work over IPv6 — it takes a minute with the IPv6 test. There is a list of popular sites in "Which Websites Support IPv6".
How to connect a proxy to a profile
- Create a profile and open its proxy section.
- Choose the type: every anti-detect browser understands SOCKS5; pick HTTPS if your program lists it.
- Paste the whole proxy line or fill in the fields: host, port, login, password. If the program doesn't accept a line from our list, convert it with the converter — see the guide on proxy formats.
- Turn on time zone, language and geolocation detection from the proxy IP — in many anti-detect browsers that is a single setting.
- Launch the profile and check that everything matches (see below).
How to check a profile
Open a checking service in the profile and see what the website sees:
- IP address — it should be the proxy's address. For an IPv6 proxy, that is an address with colons.
- Country, time zone and language — they should match each other.
- WebRTC — it must not show your real IP. This is a common leak: the browser can tell the website your real address, bypassing the proxy.
For IPv6 proxies, use services that work over IPv6 themselves, such as browserscan.net, pixelscan.net, iphey.com or ipleak.net. At the time of writing, the popular whoer.net and browserleaks.com don't work over IPv6 — they simply won't open through an IPv6 proxy, and it is easy to conclude that the proxy is broken.
For the same reason, the built-in proxy check in some anti-detect browsers may report an error for an IPv6 proxy that actually works: it calls a service without IPv6. If the check "fails", open an IPv6 website in the profile — google.com, for example — and see whether it loads.
Common mistakes
- One proxy for several profiles. The website will link the accounts by IP however different their fingerprints are.
- The proxy's country doesn't match the time zone and language. Turn on detection of these settings from the IP.
- Changing an account's IP often. An account needs one stable address, not a new one at every login.
- A website without IPv6 through an IPv6 proxy. It won't open — check the site in advance.
- Checking on a service without IPv6. An error from the checking service isn't an error in the proxy.
FAQ
Can I use an anti-detect browser without a proxy?
Yes, if you only need one account on a platform. But then every profile goes online from your own IP, and for several accounts the anti-detect browser loses its point.
Which protocol should I choose — SOCKS5 or HTTPS?
Every anti-detect browser supports SOCKS5, so it causes the fewest problems. HTTPS encrypts the connection to the proxy, but not every anti-detect browser can use it. More in "HTTP, HTTPS or SOCKS5".
How many profiles can share one proxy?
For accounts on the same platform — one. If the accounts are on different websites and a link between them doesn't matter, profiles can share, but a separate proxy for each is still safer.
You can pick IPv6 proxies for your anti-detect browser in our configurator: country, quantity and a term of 30 to 180 days.
