For security reasons, it is not possible to change your username.
Since only one account is allowed per person, it is also not possible to create a new account with the username of your choice. You will therefore have to keep the username you chose when you registered.
However, you can change your email address by clicking "forgot password or email?".
You can then authenticate with Itsme to change the email address linked to your player account. You will also need to choose a new password.
If this does not work, please feel free to contact our teams and attach a photo of the front and back of your ID card, along with your new email address.
