If you want to share with more people than the account sharing limit, you can share your own TP-Link account, and there is no limit to the number of devices logged into the same TP-Link account.
Please note that the Tapo app does not support simultaneous login with multiple accounts. To access multiple Tapo accounts, you must log out of one and then log in to the other.
