The O2 account login and password is all pre-set for you once you sign up with them. All you need to do is log on and the user interface is quite simple.
After more than a month with O2, I have no complaints... 7.50 broadband per month, free texts, free wireless modem from O2 (needs to be returned when contract is over), excellent speed, friendly customer service... all opposite to Tiscali.
