What is a password generator?
A password generator creates random, cryptographically secure passwords using crypto.getRandomValues(), a browser API backed by your operating system's entropy source. Unlike Math.random(), which is deterministic, crypto.getRandomValues() produces truly unpredictable output suitable for security use. Every password is generated locally in your browser — nothing is stored, logged, or transmitted.
- crypto.getRandomValues() ensures cryptographic randomness
- Entropy measures password strength in bits — higher is exponentially harder to crack
- Symbols add ≈30 characters to the pool, doubling the possible combinations
