Passwords are perhaps the most vulnerable element of computer security. They are the most commonly used means of protecting data, accounts, and other things you don’t want other people getting their hands on. Because of this, and because people often don’t take the time to create secure passwords, the password is the weak point in a system.
That is why it is very important to create secure passwords. Unfortunately, “secure” usually means “very random” and therefore not easily remembered. Still, there are five important suggestions you can follow to create both secure and memorable passwords.
1. Don’t use personal information in a password. A hacker could easily find out your name and other personal details, so don’t use these details in a password.
2. Don’t use real words. Password software can easily crack a password that has words found in a dictionary.
3. Mix types of characters. Use both uppercase and lowercase letters, and replace some letters in the password with different characters (like @ instead of a, and 0 instead of o).
4. Use a passphrase. Some programs can crack the character substitutions mentioned in point 3, so come up with a memorable sentence (like a quote from a movie) and use the first letter of each word in that sentence for a password.
5. Use tools. There are tools that can generate complex, secure passwords (unfortunately, these are often difficult to remember) and tool that can store complex passwords for you.
The bottom line? Passwords can be annoying, but they are, for now, necessary. So do your best to make passwords that are not completely obvious to guess, or buy a fingerprint reader.
