Last updated: July 2026
A password generator creates strong, random passwords you can't easily guess or reuse. This one draws randomness from the browser's cryptographically secure Web Crypto API (crypto.getRandomValues), not Math.random, and lets you set length and character sets. A 16-character password mixing upper, lower, digits and symbols has roughly 105 bits of entropy — far beyond brute-force reach. Nothing is stored or uploaded.

Frequently asked questions
Are these passwords secure?
Yes — they're generated with the cryptographically-secure Web Crypto API, not predictable random functions.

What makes a strong password?
Length matters most — aim for 16+ characters mixing uppercase, lowercase, numbers and symbols.
