Math.random(). The CSPRNG Cryptographic Password Generator creates military-grade, high-entropy passwords in real time. Customize character sets (uppercase, lowercase, numbers, special symbols), exclude ambiguous lookalike characters (1, l, I, 0, O), calculate Shannon entropy bits, and copy credentials with zero server logging.Password security is measured in bits of Shannon information entropy ($H$):
$$H = L \times \log_2(N)$$
