The Wizarding Passport will serve as many things, but it is essentially your login. It is also the place to create a new, enhanced profile – and a space to store all of your Wizarding World favourites, such as favourite beast, potion, spell, character and more.
If you previously registered with Pottermore, when you set up your Wizarding Passport, your details (such as your Hogwarts house, wand and Patronus) will be automatically transferred over. Your Wizarding Passport is where you can share and celebrate your traits and house pride in a new and more exciting way.
