View Permissions in Facebook Business Manager
This will help you identify who the admin is. If it is a Third Party, you’ll need to request access from the agency or individual who was running your social platform.
Log in to Facebook Business Manager and choose Business Settings
Use the menu on the left to decide how you'd like to see your permissions.
By User: Click Users. Then click People, Partners or System Users and select a user to view all users in your Business Manager and the assets assigned to them. Select an asset to view the user's level of permission.
By Account: Click Accounts, then select a type of account. Select an account to view the people who have access to it. Select a person to view their level of permission.
Business Asset Groups: Select the Business Asset Groups and the people, partners and connected assets. You can grant Group Permissions to manage and view reporting data or asset permissions for each asset type.
Instagram Accounts: If you have a personal Instagram account, you will need to switch to Instagram Business. Click Switch when prompted, you'll then be able to edit permission settings to give people, partners and apps access to your Instagram account. If you are already a business, we will require you to reconfirm your status with your username and password. This will allow you to review and approve the terms of service.
Line of Business: Select the line of business and the people, partners or connected assets. You can grant Admin access to users which enables them to manage and view aggregated insights on a line of business.
By Data Source: Click Data Sources, then click a type of data source. Select a data source to see the people who have access to it. Select a person to see their level of permission.
From here, you’ll be able to see the permissions on your account. If the admin is someone other than yourself, you’ll need to have them grant you access. You can add people to your Facebook Business Manager using this article!
