Yes, Facebook can identify multiple accounts accessed from the same IP address, such as when you open two accounts from your laptop. While IP tracking is one of the methods Facebook uses to detect unusual activities like account sharing or multiple accounts, it's not the only factor. Facebook also looks at other indicators, such as cookies, browser settings, and device fingerprints.
Key Considerations:
IP Address: Facebook tracks IP addresses as part of its efforts to prevent fraudulent activity. Accessing multiple accounts from the same IP address, especially repeatedly, may raise red flags.
Cookies & Device Fingerprinting: Facebook uses browser cookies and device information (like browser type, version, screen size, etc.) to track activity. If you're using the same browser or device, Facebook will recognize this, even if you log out and log back in.
Facebook Policy on Multiple Accounts: Facebook’s terms of service state that users are only allowed to have one personal account. Having two personal accounts may violate these rules, and Facebook could potentially restrict or ban both accounts if flagged.
If you need to manage multiple Facebook accounts (e.g., personal and business), it’s safer to create and manage a business page under one account, rather than using multiple personal accounts.
