Best Antidetect Browser for Multiple Facebook Accounts

Facebook's anti-fraud stack is one of the toughest on the internet. To keep multiple accounts alive you need three things: unique fingerprints, clean proxies, and warmup discipline.

Recommended browsers

• Dolphin Anty — purpose-built for FB media buyers, native ad-account manager.
• AdsPower — RPA warmup templates included.
• Octo Browser — highest fingerprint quality if budget allows.

Proxy choice matters more than the browser

Use residential or mobile proxies, one sticky IP per profile, matching the account's country and timezone.

Warmup checklist

1. Age the profile 3-7 days on organic activity.
2. Add a real phone number and 2FA.
3. Post 1-2 pieces of content before running ads.
4. Never share cookies between profiles.

FAQ

How many FB accounts per proxy?

One account per residential IP is safest; 2-3 max on the same mobile IP.

Does Dolphin Anty flag accounts?

No — it hides fingerprints; account bans come from behavior and IP quality, not the browser.
