Customer Portal - Reset Password

Did you forget your password? No problem! Here, you can reset your old password and create a new one.

Note: Your password for the customer portal is identical to your password for the Tai-Pan security data service! If you have stored and verified your email address in our customer portal, we will send you a link by email with which you can reset your password and then re-assign it. To do this, simply enter your six-digit customer number (ID) or the e-mail address stored with us in the input field above. Please note that you will also have to re-enter your new password for price data retrieval in the Tai-Pan stock exchange programs.
