Password Generator

A strong password is the single highest-leverage security choice a person makes. Long, random strings defeat both brute force and dictionary attacks; the only safe way to generate one is with a cryptographically secure random number generator.

This tool produces passwords from 4 to 128 characters using any combination of lowercase, uppercase, digits, and symbols. Every character comes from the browser's CSPRNG, so the output is unpredictable even to the page itself. Pick a length you can remember (or store in a password manager) — 16+ characters with mixed classes is a great default for most uses.

Enable Exclude look-alikes to drop characters like 0/O, 1/l/I that are easy to misread when typing. The strength meter estimates entropy in bits using the log2(pool size) × length formula.
