@JohnSmith729 As the master account holder, you only have direct control of the subscription itself:
You can invite/remove accounts from the subscription
You can manage the subscription settings (update billing preferences/cancel)
If you are the owner of the additional accounts on your family plan, then you can log in using the email address and password you used to create them with.
If you are not the owner of those additional accounts, then the only way you will be able to access them is if the owners of the accounts provide you with their log in credentials.
Hope this helps clarify. Thanks for being a part of the community!
