About This Tool
NewPasswordGenerator is a free tool that creates strong passwords and checks password strength entirely in your browser. No data is collected or transmitted.
Built by Dr Alex J Martin-Smith
This tool was created by Dr Alex J Martin-Smith to provide a simple, trustworthy password generator with no hidden data collection. It is designed for everyday users who want better online security without complexity.
How it works
- Browser-local processing: All password generation and checking runs in your browser. Nothing is sent to any server.
- Web Crypto API: We use the browser's built-in cryptographic random number generator for genuine randomness, not pseudo-random functions like
Math.random(). - No server storage: We do not store, log, or transmit any passwords or personal data. There are no analytics trackers, cookies, or third-party scripts.
- No sign-up required: The tool is free to use with no account creation.
What the tool offers
- Password generator: Create passwords of any length with configurable character sets, ambiguity exclusions, and real-time entropy estimation.
- Password strength checker: Evaluate any password's strength with entropy calculation, pattern detection, and estimated crack time.
