How could you find the number of different combinations of six letters in a computer password?

When trying to work out how many different combinations there are, you need to know how many options there are for each value. If the password only contains lower case letters, then we have 26 options for each value. For each letter in the password, there are 26 options, so the total number of possible options is 26x26x26x26x26x26 or 266 This equals 308,915,776 so there are 308,915,776 possible different combinations of six letters.

How a password protects data against crminal elements?

Passwords allow only authorised people to view the information. Without the password - the data remains secure. Passwords can be any length (usually a minimum of five characters) - and made up from numbers, letters and other characters. The longer the password - the more secure it is. For example... say you need a password of just numbers and letters... a five digit password would have a possible 60,466,176 combinations. However a ten-digit password would have 3656158,440,062,976 possibilities !

Can you help me make a good password?

It depends what the password is for. A 'good' password should consist of at least 10 characters. It should be a mixture of letters and numbers - but NOT something that could be guessed by someone who knows you. For example - the password I use to access my bank account online... has ten characters - and comprises 6 letters and 4 digits. I have NEVER revealed it to anyone - which makes guessing it almost impossible !Whatever password you choose - it should be something that you can easily remember - but nothing too obvious. How abut the name of your first pet... plus the year you were born.Just for reference... a 10-digit alphanumeric password has...3,656,158,440,062,976 possible combinations !
