From the account tab, click on user profile. From here you can click change password to change the password for the account. Click on Edit Profile information to change notification settings, or the email that is associated with the account.
Once you click on Edit Profile Information, you will be able to change the email address for this account, add a secondary email address for this account, or change any notification settings for the account.
Once the changes are made, you will need to click Save at the bottom of the screen, and it will prompt you for a PIN. The PIN will be sent to the original email that was on file to ensure you have the permissions to change these settings.
Once the PIN is entered, the changes that were made will come into effect.
