How to have secure passwords.

We all have connection to the internet and we create our user profiles in the many websites some are even social networks.But a number of people with evil deed always try to access our profiles with out our knowledge and change our details ,we call them hackers and crackers, me being one of them.Some even hack into our bank accounts and steal our money some even use our bank details to buy goods online.Now to protect your profiles you must have a secure and a more easier password that you can easily remember-not the one that other people can easily remember.
A good password has the following characteristics.
*The password must be easier for the account user to remember other than that it should not be attached to any thing that is in your personal details.
*The the password should contain both the alphabetical characters and the numeric keys or the special symbols.For example a password may be :Amendek105286$%~ ?,this password is more secure than 12345678 which is the common password .
*You can also mix the capital and small letters together for a more secure password imagine a case where one has known your password but does not the know the characters that are capital and those that are small letters.Thank you and make your passwords more secure.
