Use the Family Manager Dashboard
With a LastPass account for up to six family members, LastPass Families allows everyone to easily store and access all their passwords and information. The lead Family Owner purchases the subscription and is able to designate additional managers, as well as add and remove family members.
Once you create a LastPass Families account, you are both the Family Manager and Family Owner. As the Family Owner, this means another Family Manager cannot remove your admin rights (i.e., downgrade your role to be a family member) or remove you from the account.
For more information, please see LastPass Families FAQs.
