Password Generator

A cryptographically secure password generator that creates strong, unpredictable passwords using the browser's native Crypto.getRandomValues() API — the same randomness source used by modern operating systems for cryptographic operations. Unlike Math.random()-based generators that produce predictable output, every password generated by this tool passes through a cryptographically secure pseudorandom number generator (CSPRNG). You control every aspect of password generation: set the exact length, toggle uppercase and lowercase letters, include digits, symbols, and extended special characters, and exclude ambiguous characters like 'l', '1', 'O', and '0' that cause confusion. The generator also supports passphrases — memorable sequences of random dictionary words separated by a delimiter of your choice — and numeric PIN codes for simpler use cases. A real-time strength meter visualizes password entropy to help you make informed decisions. The entropy-based strength evaluation follows NIST guidelines, estimating how many guesses an attacker would need on average. All generation happens entirely client-side; no passwords ever leave your browser. Ideal for generating API keys, database credentials, SSL private key passphrases, user account passwords, and any scenario where cryptographic randomness matters.
