Logged into alphatheta on Google Chrome/password not ported over to new Rekordbox install

As the title states, I am currently logged into my alphatheta account on google chrome, have just downloaded the latest release of Rekordbox for MacbookPro running Sequoia 15.7.  When I open Rekordbox it asks me to log in, but I do not know my password by heart, it usually gives me the option to autofill it, however this is not happening.  What do I do?
