Mathod to be Strong Passwords



One of the easiest ways for someone to gain access to your account is to determine your password. Here are some suggestions for creating passwords:

  • Use at least 8 characters when creating a password.
  • Include letters, numbers, and special characters such as @, #, *, $.
  • Use upper and lower case letters.
  • Don’t use commonly spelled words. For example, instead of using “sunshine” you might use “L3tTh3$$hIne” instead.
  • Don’t write your password down – memorize it. You might easily remember the phrase “Let the Sun Shine” to remember L3tTh3$$hIne.
  • Don’t give your password to anyone else.
  • Change your passwords routinely – at least every 60 days.

How Fast Can Someone Guess Your Password?

The table below is calculated by assuming 100,000 encryption operations per second. This is a plausible number for a desktop PC today. Password lengths from 5 to 12 are shown. The numbers at the top, 26, 36, 52, indicate the number of characters from which the passwords are formed. The times shown are the times to process the entire set of passwords thus the average time to crack passwords would be one half of the listed times.

Strong Passwords

Strong passwords cannot be guessed easily. Hackers often use automated tools to help them guess or crack passwords, and the easier a password is to guess, the faster a hacker can break into a system. Here are some guidelines to assure your passwords are strong:




Many people write down their secret password, and tape it to the monitor or tuck it into a desk drawer next to their computer. The following are a few recommendations for handling your passwords more safely:

DO THIS: DON'T DO THIS:
Keep your password secret Write down your password
Use different passwords for different web sites Use the "remember my password" features on the web
Change your passwords at least every six months Keep the same password for a long time or keep reusing old passwords
