Q&A: Facebook Admins
Question: “Do I need a separate Facebook account for my business?”
Answer: No you do not need a separate account for your business. You use your personal account to set-up a business page for your business, and then manage the page as an admin. A page can have several admins, so the owner, managers, tech support people can all have access to the page. You can add and remove admins as needed.
“Will users be able to see that I am a Page admin and contact my personal profile?
The people who connect with your Pages will not be able to see or access to your personal profile. Any actions that you take as a Page administrator on your Page will show the Page’s name as the author and not your personal name.” Facebook Help
