Unless you are willing to do the math, “no entropy really” deserves a [citation needed]
what kind of password has more entropy? one with capital and lowercase letters, numbers, math symbols and puncuation marks?
or the one with only numbers?
Is there really a citation needed for that?
Entropy is calculated from the character set size to the exponent the length of the string: E = log2(R^L). A long string of numbers can have more entropy than a shorter alphanumeric string with special characters. I looked it up and apparently their account number is 16 digits. That’s 53 bits of entropy, which is not guessable. Someone brute forcing would have quadrillions of login attempts to try.
