To change your password, click on the person icon in the toolbar and select Account. You’ll be greeted with the screen below. You will be required to re-enter your current password, and then your new password, plus that new one again to confirm.
Don’t forget that there is a "Forgot password?" link on the sign in page, just in case you change it and forget the new one.
If you are having trouble resetting your password, send us a chat or email at support@attunedpartners.com.
