Question

I cannot log in anymore to Lufthansa privatebase because I need to have a new password.

Answer 1

The access to the database is done using a token which provides you with a PIN so beside your normal password you will have to enter the PIN next to it.

As on the page there is no support links provided you will need to contact the company to resolve this issue because only they can help you.
