When first playing Harry Potter: Hogwarts Mystery, you design your character and choose their name. Fortunatley, both of these options can be changed after the tutorial. Right now, it seems the only thing that can’t be changed is which house you choose.
Whether you pick Gryffindor, Slytherin, Hufflepuff or Ravenclaw, you’re stuck with it! In this quick guide, we’ll show you the steps needed in order to change your characters name when playing. You can choose to change both the first name and last name of your player.
Changing your character name

To start, get to a point in the game where you can access your profile settings. You can get there by pressing your character portrait in the top left of the screen.

Next, you will see your name and what year you are in, at the top left of the screen again. Press the edit icon to choose your first and last name. There is also a Random option, if you want the game to randomly assign one to you.
It seems you can change your name as many times as you want in Harry Potter: Hogwarts Mystery.
