The BritBox shared plan at JoinBareng uses credential access, meaning you log in to a shared BritBox account with other co-subscribers. The basic plan currently open is the BritBox Monthly for 1 user, so for now you get a personal slot on a shared account. Group plans with up to 3 people per monthly period will open later, following similar rules.
Because it is a shared account, every member must avoid changing the password, email, or logging out other devices without coordination, as this disrupts the other members. If the group is not yet full, your order will wait until the slot is filled, and JoinBareng's admin will activate the account and send the credentials once the group is ready. You can check the status via WhatsApp while waiting.
The shared subscription price is shown automatically on the plan card on the product page, and is not necessarily the same as the pay-for-service price because it is calculated per slot. Payment is processed via QRIS to a Bank Indonesia licensed payment provider, so the transaction stays safe and recorded. Reach the admin via WhatsApp if you have questions about the usage rules or the activation process.
