Managing Your Team in iTunes Connect
Add a person to your team in iTunes Connect to allow them to submit and manage your apps for sale in the App Store.
In iTunes Connect, select Manage Users.
Select iTunes Connect User.
Perform the appropriate management task.
You use the iTunes Connect interface to manage iTunes Connect user accounts for members of your team, as well as test-user accounts, which are used for testing In-App Purchase code in the sandbox.
iTunes Connect users are distinct from Member Center accounts; adding someone to your team using Member Center does not give them access to iTunes Connect.
