How to Add A User To Your Facebook Business Page
There may be other people within your business or social media managers who also need access to your Facebook page to add new posts to the business page. The guide below will show how to add these users to your Facebook page.
The admin on your Facebook Business account needs to:
1. Click Settings at the top of your Page
2. Click Page Roles in the left column
3. Type a name or email in the box and select the person from the list that appears.
4. Click Editor to select a role from the dropdown menu.
5. Click Add and enter your password to confirm. (Keep in mind that if you’re not friends with the person you’re adding, they’ll have to accept your invite before they can start helping you manage your page).
