To change your password, click on the icon of your account in the top right corner of the website. Then click on "Edit Profile".
Enter your current password, then create a new one. If you fail to remember your old password, log out of your account and use the "Forgot password" form.
Please note that we will not be able to change the password in an account where the login is done through social media. In that case, you will need to do it yourself in the settings of the social media account.
