browser-generate-password

A simple function to generate a random password on demand. It uses window.crypto when available to help make it more randomer.

Usage

Install with: npm install browser-generate-password

Then use in your project:

import genPassword from 'browser-generate-password';

const password = genPassword(15); // 0{9gSE)Mc9Pj1Ja

Testing

A full test suite is included. To run it:

1. Clone the repository, and cd into it
2. Install dev dependencies: npm install
3. Run node.js tests: npm test
4. Build browser bundle: npm run build
5. Run browser tests by opening test/browser/index.html in your browser of choice.

The browser based test suite also includes a histogram showing character distribution in the generated passwords. It's a nice way to see how uniform it comes out in your browser.

You will see the numeric characters skew higher in the histogram because the function ensures there is at least one number in the generated password. This isn't really ideal, but since so many websites require a number, it makes sense to do it.
