This Manus shared plan uses a single account with credential sharing. Once your QRIS payment is confirmed, the JoinBareng admin will send login credentials to your WhatsApp. You can log in to Manus right away using the slot allocated to you. The base plan is Pro Tier 1 on a monthly basis with a maximum of 3 people per group, so the per-slot cost is lighter than a solo subscription.
There are a few important rules so everyone in the group can use the account comfortably. Do not change the password or email, do not intentionally log out other devices, and use only the slot assigned by the admin. Breaking these rules is the most common reason shared accounts run into issues, so make sure to follow the admin's guidance.
Right now, the 1-user (private) package is open while the group package is coming soon. If you have already paid for a group package but the group has not been filled, your payment will be held until the group is full or until the agreed deadline. You can reach the admin via WhatsApp to ask when the group package will be available or to switch to the private package.
