Things to keep in mind before creating a password

Use a combination of uppercase and lowercase letters, symbols amd numbers.

The more characters your passwords contain, the more difficult they are to guess.

Try to make your password meaningless and random as possible.

Set up a routine, changing your password on every month.

Never write your password down, and never give them out to anyone.

Don't use names or numbers associated with you, such as a birth date or nickname.

Don't use your user name or login name in any form.

Don't answer "Yes" when prompted to save your password to a particular computer.
