No sane person every time someone else reading your email. Or in the case of someone else using your password and enter a financial institution. Must therefore choose a secure password, secure, so that would be a tough nut to crack for others and easy to remember. The more random and mixed up you do, the more difficult for others to crack. Of course, if your password is compromised, the password crackers, even take over your identity.

A password, if it is too short, is vulnerable to an attack if an attacker gets hold of the cryptographic hash of the password. Today's computers are fast enough to try all alphabetic passwords less than seven characters. We call a weak password is short or if a defect, or it can be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary of names, own, words based on your user name or common variations on these themes.

Moreover, a strong password would be sufficiently long, random, or can be produced only by the user who elected him, so 'guess' it will require too long.

For safety, you should follow some simple guidelines:

1) Passwords should preferably be at least 8 characters and no more than 14.

2) Passwords should contain a mixture of numbers, letters and special characters (% & @ 3ac_ht4 m7).

3) Passwords should not contain a dictionary word in any dictionary, either French, Spanish physician, etc.

4) Each password must be different from the user's user-ID and any permutation of the user ID.

5) The new old passwords and must differ in at least 3 characters.

6) Avoid picking the names or nicknames of people, pets, or places, or personal information that can be easily discovered, such as your date of birth, address, etc.

7) It is advisable to stay away from the common keyboard sequences like dfgh678 or abc345.

Never make a password if you add a digit to the word. That may be easy to guess.

9) Avoid writing your password or store on your computer.

10) Never share your password with anyone else.
