I am absolutely sick of passwords. There is no good reason that I should have to enter a username and password for anything more than once anymore. I shouldn't need to do it to check webmail from my home PC. I shouldn't need to do it to play World of Warcraft. I shouldn't need to do it to log into websites. It just doesn't make any sense. How entrenched are we that we aren't making significant progress in this?
I'm not as angry that I have to use a username and password on smaller, independently-run sites... though there should be a service that provides secure authentication for a low fee. But there's no excuse that I have to use a username and password to access my work mail from my home machine; Microsoft can afford $200 for an SSL certificate. Same with Amazon and eBay.
There are people that, for some reason or another, leave their computers running and logged in and unlocked. They should still be able to set up a secondary password that protects their credentials. But I diligently lock my computer. I shouldn't be forced to deal with it.
