I do not know my password. It is senseless to know it as it does not provide more entropy as the backup mechanism to retrieve the password. To retrieve the password, I have to enter 4 fixed digits of my account number and my birth date. As I have quite unique name then also my birth date is not very hard to find. That leaves 14 +/- 2 to 4 bits of entropy and makes it pointless to actually somehow keep track of the real password. So I just generate a temporary password. Edit: This is of course how my bank has implemented it. Your experience my possibly vary.
