问题     Are passwords passe(过时的)? It’s starting to seem like it. Everybody hates them, and nobody can remember all the ones they’ve created. These days a【C1】_____netizen(网民)has dozens of online accounts. If you really want to be safe, you need to have a different password for each one, and each password needs to be【C2】_____complicated, with a mix of【C3】_____letters, symbols, and numbers. Who can keep all that stuff in their head?
    Most people don’t【C4】_____. Some just【C5】_____one password and use it everywhere. Problem is that【C6】_____one site gets hacked, the bad guys now have the password that you use elsewhere. In one recent attack on Sony, millions of accounts were【C7】_____. Computer scientists【C8】_____the system is broken, and they’re looking for【C9】_____. But most【C10】_____haven’t been very good.
    Markus Jakobsson, a veteran security researcher with a Ph. D. in computer science, has【C11】_____up with something he calls "fastwords". Instead of inventing a complex password, you join three simple words that come from a thought【C12】_____only to you. If one day you were driving to work and ran【C13】_____a frog that ended up flat, you might choose "frog work flat".
    You can enter the three words in any【C14】_____, and the system still knows that you’re you. If you【C15】_____forget, the fast word system will tell you one of the three words, which should enable you to remember the【C16】_____thought. Jakobsson says one large service provider is【C17】_____the fastwords concept.
    Fastwords represents a step【C18】_____the right direction, but it’s not the promised land. Someone,【C19】_____, needs to come up with something radically different — and radically better —【C20】_____what we have today.
