A secret series of characters that enables a user to access a file, computer, or program is Password. On multi-user systems, each user must enter his or her password before the computer will respond to commands. The password helps ensure that unauthorized users do not access the computer. In addition, data files and programs may require a password.
Ideally, the password should be something that nobody could guess. In practice, most people choose a password that is easy to remember, such as their name or their initials. This is one reason it is relatively easy to break into most computer systems. Here are 10 tips for creating strong password.
1. Use a strong password. A strong password contains a combination of six or more uppercase and lowercase letters, plus punctuation and numbers. Using all four types ofcharacters works the best. For example instead of using welcome use W3Lc0mE^9.
2. Passwords should be eight or more characters in length. The longer the password, the harder it is to crack.
3. Never use the same password twice. If, for example, your eBay account were hacked and your password obtained, the hacker would have instant access to your PayPal account if you use the same password.
4. Do not use common information in your password, such as birthdates, your phone number, or other information directly related to you.
5. Passwords comprised of characters rather than proper words are more secure.
6. Refrain from writing passwords down and do not login to accounts via a public computer (e.g., at the library or Internet cafe) and save the password details in the browser.
7. Never click an e-mail link and log into a secure site from an e-mail. Even if the e-mail looks legitimate, always type the URL into a browser yourself, then log in to your account. This will help you avoid phishing attacks.
8. Do not allow applications to store your passwords online, and remember to clear your browser cache, history and clear passwords frequently.
9. Remember to change your passwords frequently. The more important the account, the more frequently the password should be changed.
10. Never communicate a password to anyone, especially via e-mail or instant messenger. Passwords should always be kept private.
