This video explains in detail how to run multiple Facebook ad accounts on the same device safely without being detected and banned by the platform. It first analyzes the core reasons for account bans: Facebook identifies multi-account behavior on the same device through IP addresses and browser fingerprints. Then, it systematically introduces a complete solution for creating a clean, isolated environment: using proxy servers to change IP addresses, combined with anti-detect browsers (like Hide My ACC) to modify browser fingerprint parameters, thereby simulating real, independent users. The video demonstrates the entire process from installing tools, creating profiles, adding proxies, customizing fingerprint parameters, to finally achieving batch account nurturing for multiple accounts. Compared to VPS solutions, anti-detect browsers are less costly and have a lower technical threshold. They can generate independent operating system, browser version, hardware parameters, and other fingerprint information for each account. Combined with automation scripts, they can also achieve batch account nurturing, greatly improving the efficiency and security of multi-account operations.
