Whats the difference between the terms password, pass phrase, and passcode?
People have used the terms interchangeably. However, technically speaking, a passcode can be a combination of any type of character, including letters (upper and lower case), numbers, and symbols. The terms password or pass phrase, on the other hand, connote words or letters or a combination of words. Because of the significantly greater string combinations brought about by the addition of numbers and symbols, a Passcode is vastly more secure. Refer to the Chances of Guessing above.
