No offence taken - its a good question! I'm on a laptop, and I rely heavily on the website keeping me logged in, or on the function where my laptop automatically remembers my username and password. Without that I am completely lost.

I am definitely not the same me every time I log on. I have a hundred twitter accounts, forum accounts, and anything else online that requires a username and password that I have vague memories of creating but have no idea how to log on again. Much of the time I don't even know which email addresses I used to create the accounts, to ask for password reminders! A good example is my iTunes account - I have to reset that password at least once a month, as it only lets you fail twice before having to reset, and I fail every time I try!
