Choosing a Secure Password
Password should be:
6 to 20 characters long.
At least 4 different characters.
At least 1 number or symbol.
At least 1 character that is not a number.
Not based on your email address, displayed name, or a commonly-used password.
Here are some guidelines to help you choose a secure password that you can also remember:
Use a combination of lowercase and uppercase letters.
Use a password containing multiple words or even phrases, not just a single word.
Use the first letter of words in a memorable sentence to create the password.
Do not use a password based on available or easily-discovered information about you, such as your name, birthdate, pet's name, student ID number, telephone number, license plate number, or other personally significant dates/numbers.
