How do I limit which Meta and Google accounts a member can see?

When adding or editing a member, use the Allowed Meta ad accounts and Allowed Google Ads accounts fields to select only the accounts that person should access. From then on, they see only those accounts across the entire system (manager, Account Center, reports and balance). If you leave the list empty, the member has access to all your accounts, with no restriction. This is how you give each team member only the clients they are responsible for and keep the other accounts out of reach.
