選擇安全的密碼

確保密碼對您而言容易記住，卻又難以被他人猜到（包含電腦程式）。

選用好密碼能確保您電腦的安全。倘若密碼容易被猜到，則您的個人資訊容易遭到有心人士利用。

People could even use computers to systematically try to guess your password, so even one that would be difficult for a human to guess might be extremely easy for a computer program to crack. Here are some tips for choosing a good password:

  • 在密碼中混用大寫、小寫、數字、符號、空格等字元。這樣做能讓密碼難以被猜到；並且符號種類眾多，能創造出更多的密碼組合，使別人再怎麽嘗試也試不出您的密碼。

    A good method for choosing a password is to take the first letter of each word in a phrase that you can remember. The phrase could be the name of a movie, a book, a song or an album. For example, “Flatland: A Romance of Many Dimensions” would become F:ARoMD or faromd or f: aromd.

  • Make your password as long as possible. The more characters it contains, the longer it should take for a person or computer to guess it.

  • Do not use any words that appear in a standard dictionary in any language. Password crackers will try these first. The most common password is “password” — people can guess passwords like this very quickly!

  • 不要使用任何個人資訊，像是生日、車牌號碼，或是家人的名字。

  • 不要使用任何名詞。

  • Choose a password that can be typed quickly, to decrease the chances of someone being able to make out what you have typed if they happen to be watching you.

    永遠不要將密碼寫下來，這樣做很容易被找到！

  • 對不同的事情使用不同的密碼。

  • 對不同的帳號使用不同的密碼。

    If you use the same password for all of your accounts, anyone who guesses it will be able to access all of your accounts immediately.

    It can be difficult to remember lots of passwords, however. Though not as secure as using a different passwords for everything, it may be easier to use the same one for things that do not matter (like websites), and different ones for important things (like your online banking account and your email).

  • 時常更改密碼。
