After i seen so many users had been cracked because of poor password, here i summarize 5 of the strongest password that i know. Hope this help.

No 5 – Combine partial 2 or 3 or even 4 unrelated words together (mix uppercase and lowercase)
User can combine 2 words together like “Diamond”, “Blog”,”Security” to become “DiamBloSecu”

No 4 – Combine word with number and (mix uppercase and lowercase)

User can combine your name and your handphone number together, like your name “Scotfield”, handphone is “01255447689″, then your password will become “Scotfield01255447689″, this is my favourite password to use also, because it is consider strong and easy to remember password.

No 3 Replace Word with number and symbol randomly. (mix uppercase and lowercase)
Good example is microsoft suggest strongest password P@ssw0rd, it replace a with @ symbol and o with 0 (Zero), This will need some creative to think of it.

No 2 Mix Word and number together randomly. (mix uppercase and lowercase)
Let said, “Scotfield” and “01255447689″, if we mix randomly to become “S012cot5544fie76ld89″, frankly… i do not think is it possible to crack it..but it very hard to remember also.

No1 Mix meanless Word, number and symbol randomly, and at least 15 length.
(mix uppercase and lowercase)
Strongest password equals to hardest remember password, for example

E7r9t8@Q#h%Hy+M

er…. if possible please do not create above strongest password, because this is really very hard to remember.
