Choose a password you'll remember
It should be memorable for you (so that you don't have to write it down or leave it in the open), but difficult for others to guess.
Don't use personal information that someone could easily figure out
Avoid a password based on information easily obtained about you (like your birthday, your child or pet's name,
phone number, license plate number, employer, school name, automobile brand, or street name).
DON'T use a password you already use for another account, such as your bank account PIN. And DON'T use your name in any form (such as reversed, capitalized, or doubled).
Avoid the obvious
Avoid a complete word from a dictionary (English or otherwise) or a well known name like John.
Avoid using a word
Don't make it easy for attackers by repeating a digit or letter (like "111111" or "FFFFFF") or any other common sequence of characters (like "123456"). Stay away from obvious passwords such as "test" or "password." When you change your password, change several characters; don't just append a number like "2" to the end. And make sure anyone watching you enter your password can't guess it as you type (such as a password typed using a single hand, like "qwerty").
Put a new spin on a familiar phrase
Pick a favorite phrase or lyric for your password. To shorten it, substitute letters with a number or a standard symbol or remove vowels. For example, "fredsboy" can be made into "Fr3d$boy." Shorten "two tickets to paradise" to "2Tickets2Paradiz," or combine "cat" and "dog" into "cAt!Do8."
Use at least 7 characters
The more characters your password contains, the harder it is for someone to guess it. A long but simple password can be safer than a short, complex one — and often easier to remember.
Use a combination of capital and lowercase letters, numbers, and standard symbols (! @ # $ % ^ & *)
Passwords are case-sensitive, which means that a capital letter A is different from a lowercase a. Adding a symbol can strengthen even the simplest of passwords, since it would be very difficult for another person to guess which symbol you used.
