You can change your password once you have logged in to your account by visiting the “My account” section, choosing ”My data” and then clicking on ”Change password”.
We always suggest changing your password if you suspect that somebody else may know this password.
When choosing a new password, we reccomend that you choose an obscure password that nobody would be able to guess. This could be for example a combination of letters and numbers.
Additionally, we also highly recommended that you change your password regularly maybe every 2-3 months to ensure security and integrity of your account at all times.
