Military Star credit card holders can allow their eligible dependents to use their cards, but they must designate them as authorized users on their credit card applications or subsequent written documents. Authorized users must be eligible for Exchange privileges and be at least 18 years old.
Only a Military Star account owner can add or remove an authorized user from the account. To remove an authorized user, the account owner must make a written request or phone the Exchange call center. Authorized users can use the card to make purchases and payments, but they cannot change account information such as email or mailing addresses. The account owner is responsible for any purchases that authorized users make.
