Each character you add to your password increases the protection it provides.
8 or more characters are the minimum for a strong password; 14 characters or longer are ideal.
The greater variety of characters that you have in your password, the harder it is to guess.
An ideal password combines both length and different types of symbols.
Use the entire keyboard.
The easiest way to remember your passwords is to write them down.
It is OK to write passwords down, but keep them secret so they remain secure and effective.
