Some time it is hard to remember your own password. Too simple a password makes it easier for somebody else to guess your password. As a solution, you can mix numbers, small letters, capital letters, and symbols to compose your password.
First, think two or three words that are easy for you to remember. For example, use your own name such as JOHN SULLIVAN. Next, change the "O", "I", and "S" letters with "0", "1", and "5" numbers, so it becomes J0HN 5ULL1VAN.
Change the empty space with ~ or & symbols, so it become J0HN~5ULL1VAN. Finally, use capital letters for the consonants and small letters for the vowels. So the final password will be J0HN~5uLL1VaN.
