How to Use Password Generator

  1. Set your desired password length between 4 and 128 characters (16+ characters recommended for strong security).
  2. Toggle Uppercase (A–Z), Lowercase (a–z), Numbers (0–9), and Symbols (!@#$%^&*) based on your account requirements.
  3. Optionally enable 'Exclude Look-Alike Characters' to omit visually ambiguous glyphs (0, O, 1, l, I, |) for easier manual typing.
  4. Click Execute Password Generator to generate unbiased Web Crypto CSPRNG passwords with bit-entropy and offline crack-time metrics.

Frequently Asked Questions

How does this password generator ensure cryptographic randomness?

Instead of Math.random(), which is predictable and unsuitable for security, EverySolve uses your browser's hardware-seeded Web Crypto API (window.crypto.getRandomValues) with rejection sampling to eliminate modulo bias and a cryptographic Fisher-Yates shuffle.

What password length and entropy score is considered secure?

A 16-character password using uppercase, lowercase, digits, and symbols (pool size N = 88) yields approximately 103 bits of entropy. Security standards generally recommend at least 80 bits of entropy for standard accounts and 100+ bits for master passwords or administrative credentials.

Are generated passwords stored, logged, or transmitted to any server?

No. Password generation runs 100% locally inside your browser memory using client-side JavaScript. No generated password string is ever transmitted to EverySolve servers, saved in databases, or recorded in analytics.

Why should I exclude ambiguous or look-alike characters?

Characters like zero (0) and capital O, or one (1), lowercase L (l), and capital I look nearly identical in many sans-serif fonts. Excluding them prevents transcription errors when typing a password onto a smart TV, mobile phone, or hardware console.

Does the generator guarantee at least one number and symbol when those options are checked?

Yes. Whenever the requested password length is at least as large as the number of enabled character classes, the engine selects one unbiased random character from each enabled class first, fills the remaining positions from the combined pool, and performs a cryptographic Fisher-Yates shuffle.
