Facebook prohibits managing multiple accounts. If anti-fraud systems detect that a single user is managing different accounts, they may freeze or completely ban all connected pages.
Using an anti-detect browser like
Octo allows safe management of multiple accounts on Facebook. Octo spoofs the digital fingerprint of your device, the set of parameters websites use to identify their visitors. Digital fingerprints can include such information as the operating system and browser versions, user agent, geolocation, time zone, language, installed fonts, the GPU model, etc. Using an anti-detect browser you can create separate virtual profiles for each Facebook page, each with its own fingerprint, making your accounts appear as different users to the social media platform.
For complete safety, use an anti-detect browser together with proxies. Connect different proxies to individual profiles to ensure their IP addresses do not match, protecting your accounts from bans for multi-accounting.
