The passwords you use to access online content and websites are something that many hackers around the world attempt to hack. In many places on the Internet, we are required to provide a password in order to gain access to various services. This includes forums, your bank account, members-only websites, online games, etc. While you cannot completely stop hackers, you can outsmart them by making a difficult password. There are many tricks that you can use: both upper and lowercase characters combined, symbols and numbers mixed together, combination of words in two different languages, etc. What you can even do is to close your eyes, and type something on your keyboard without seeing it. This will surely be difficult to hack, but on the other hand, it might be difficult to remember. Naturally, if you are going to use a password that is difficult to remember on a regular basis, you are eventually going to memorize it anyway.
Remember though that the Internet is not the only place where your password can be hijacked. It can be also done through phone, email, or even personal conversation. That is why you should not give any personal information to anyone, even if it appears legit. No legit company, no matter what it is, is going to ask you for your password. So watch out for anyone who wants to steal your password.
