Aye. You aren't supposed to browse the internet while working anyway! :P

I think it's a good idea to block those spammers and stuff. It's not much of a hassle to carry that little token with me though. I've logged in yesterday and I restarted the computer a couple times and I'm still logged in. So as long there's no server down or anything you should only log in for 1 time and then you're good to go. :O
