Password Generator
Generate strong, secure, random passwords with custom rules — all in your browser.
Why Use DiffMergy’s Password Generator?
DiffMergy’s Password Generator creates strong, cryptographically random passwords tailored to your requirements. Configure length, character types (uppercase, lowercase, digits, symbols), and exclusion rules to match any website’s password policy.
All generation uses the Web Crypto API for true cryptographic randomness, and no passwords are ever transmitted or logged. The built-in strength meter helps you gauge password security at a glance.
100% Private — No Server Upload
All processing happens entirely in your browser using Web Workers and modern browser APIs. Your sensitive source code, credentials, and files never leave your device — no servers, no databases, no tracking, no sign-up required.
Fast & Reliable
Built with vanilla TypeScript and a lightweight custom engine, DiffMergy delivers sub-millisecond processing with zero network latency. The entire toolkit works on any modern browser across all operating systems, with no installation or setup needed.
