Password (密码) 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 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.

One argument against LastPass is that if their database is attacked, then all of your sites are in danger, and that's true, but given that their entire line of work is keeping that information safe, I'm willing to take that chance. The alternative is rolling dice(掷骰子) or picking phrases to create passwords, writing all of them down on a piece of paper or something, and then having to manually type them in when I go to a site. A terrible mess.

There is a free version of LastPass, with some additional features unlocked if you pay a $12 a year subscription.
