How it works › Users and accounts
A name, an avator and a secret sequence are not fixed at creation. Change any of them later under Manage Users on the account page, with ‘Edit details’ — it is the same user afterwards, with every sum, its village and its wood still there. The guest is the one exception: having no name is what makes it the guest, so giving it one is the upgrade, which has its own button and leaves the device with a fresh guest.
