[2016·武邑中学月考]Password strength has been a topic about the Internet lately. I have seen lots of clever methods for generating and remembering strong passwords. Some are better than others, but in my opinion, none are adequate. Here's the problem: it doesn't matter how strong your passwords are if you use the same one on multiple sites. All it takes is for a site to get hacked (侵入), like Gawker media, or even Sony did, and now your superstrong password has been stolen, and every site on which you used that password has been accessed.
So, the bottom line is that no matter how strong your passwords are, and no matter what clever tricks you use to help you remember them, if you surf the Internet often, the only truly secure password system is what you need.
Enter LastPass. It's not the only password manager out there, but I like it the best. You create ONE strong password that you have to memorize and use it to access your LastPass database. The LastPass database is stored online, on LastPass's servers. LastPass recognizes the site you're on and automatically logs you in (after, optionally, asking you to reenter your master password). LastPass also has automatic form fill and automatic password generation. This means that you can have a different, unique, very strong password for every site you log into, but you only have to remember one master password. It's the best of both worlds.
