When running multiple accounts, most people think of changing IPs first — but browser/device fingerprints are just as important.
From my tests, even with clean proxies, if your fingerprints (resolution, fonts, plugins, time zone, etc.) are too similar, accounts can still get linked.
My current approach:
- Each account gets its own fingerprint profile
- Different User-Agents
- Keep IP + fingerprint + cookies fully isolated
This makes it much safer for account farming and daily logins. What tools do you guys use for fingerprint isolation?
