Why do I need to log on to Bitdefender Central

Using PW manager on multiple devices / platforms. Inactivity is set to 1 minute and to password login , not a pin code ( too many pin codes to remember) As I understand this means I need to provide a master password for the PW manager need to be entered to logging in again. However, my Chrome extension based devices (windows, mac) are very frequently asking for logging in to Bitdefender with the Bitdefender Central password - which is stored in the password manager ;-) - before I can actually log in and use the password manager. This means I need to use one of my mobile devices and the password app to read out the Bitdefender Account Password. Why is that so? What do I need to change to remove the needs for this annoying double login? Many kind thanks. Br
