Original: Password Generator and the case for browser-side cryptography

Short summary

A browser-based password generator uses the Web Crypto API's crypto.getRandomValues() for cryptographically secure, client-side password and passphrase generation with no data sent to servers. It offers customization of length, character sets, and ambiguous-character exclusion, plus a passphrase mode using curated wordlists. The tool is part of DevTools' 200+ free, privacy-first utilities requiring no signup.

  • •Uses Web Crypto API for OS-level entropy, not Math.random()
  • •Full client-side execution: no passwords touch a server
  • •Customizable length (8-128), character sets, passphrase mode, and ambiguous-character exclusion

Generated with AI, which can make mistakes.
