Password security is in the news again, as it is revealed that hackers had managed to break into the accounts of many Twitter users.
Many of the affected Twitter users had previously registered on P2P file-sharing sites - and hackers had been able to enter the sites through a backdoor and grab their account information (including email address and password).
Although a username and password for a torrent-downloading website may not seem very valuable, it does have a significant worth if the same email address and password is being used for a social networking site like Twitter too.
As we've explained before, you should never use the same username and password on multiple websites. It's like having a skeleton key which opens every door - if they grab your password in one place they can try it in many other places.
Also, you should ensure that your password is not a dictionary word, and is suitably complex that it's hard to break with a dictionary attack.
Here's a video which explains how to choose a strong password, which is easy to remember but still hard to crack:
