Are passwords outdated? It’s starting to seem like it. Everybody hates them, and nobody can remember all the ones they’ve【C1】______. These days a typical internet user 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 incredibly【C2】______, with a mix of capital letters,【C3】______, and numbers. Who can keep all that stuff in their head?
Most people don’t【C4】______. Some just make up one password and use it everywhere while others might have a few passwords for different usages. Problem is that【C5】______one site gets attacked by hackers, they now have the password that you use elsewhere.
In one recent attack on Sony, millions of accounts were exposed. Computer scientists realize the system is【C6】______and they’re looking for alternatives. But most【C7】______haven’t been very good. Fingerprint readers require special hardware, and smart cards can be lost or【C8】______. "We’ve tried【C9】______other approaches, but we end up back with passwords. They’re the least【C10】______in a series of bad options," says a security consultant.
Markus Jakobsson, a veteran security researcher with a Ph.D. in computer science, has come up with something he calls "fastwords." Instead of【C11】______a meaningless and obscure password, you join three simple words that come from a【C12】______known only to you. If one day you were driving to work and【C13】______a frog that ended up flat, you might choose "frog work flat."
Some【C14】______: You can enter the three words【C15】______any order ("flat frog work"), and the system【C16】______knows that you’re you. If you totally【C17】______, the fastword system will tell you one of the three words, which should enable you to remember the【C18】______idea and thus the three keywords. Jakobsson says one large service provider is evaluating the fast-words concept.
Fastwords【C19】______a step in the right direction, 【C20】______it’s not the promised land. Someone, somehow, needs to come up with something completely different— and radically better—than what we have today.
