A strong, unique password is still the first line of defense for most online accounts, and inventing one by hand usually means falling back on predictable patterns. This free password generator creates cryptographically secure random passwords right in your browser — nothing you generate ever leaves your device. Set the length, pick the character types, and get a fresh password in one click.

How to Use

  • Set length: Choose password length (8-128 characters); 16 is a good default
  • Select types: Include uppercase, lowercase, numbers, and symbols as needed
  • Exclude similar characters: Drop ambiguous characters like l, 1, I, O, and 0
  • Generate: Click to create a password and check the strength indicator
  • Copy: Copy it to your clipboard and store it somewhere safe

Features

  • Cryptographically secure random generation with the Web Crypto API
  • Customizable length from 8 to 128 characters
  • Include or exclude each character type
  • Real-time password strength indicator
  • Option to exclude visually similar characters
  • 100% client-side: no server, no logging, no storage

What Makes a Password Strong?

Length beats clever substitutions. Every extra character multiplies the combinations an attacker must try, so a 16-character password drawn from a pool of about 90 characters is far beyond practical brute-force attacks — while a short password falls quickly even with symbols mixed in. Two habits quietly undo good passwords: reusing one password across sites, so a single breach exposes every account, and tweaking dictionary words (like swapping “a” for ”@”), which cracking tools try first. Random generation avoids both traps, and because this tool uses crypto.getRandomValues() instead of a basic pseudo-random function, the output is suitable for real security use.

Use Cases

  • Account security: Create strong, unique passwords for email, banking, and social accounts
  • Password managers: Generate a long master password or fill in new entries
  • API keys: Mint random secrets for development and testing
  • Temporary access: Issue one-off passwords for shared or demo accounts

Frequently Asked Questions

How secure are the passwords?

Passwords are generated using crypto.getRandomValues(), which is cryptographically secure.

What makes a strong password?

A strong password is long (12+ characters), includes mixed character types, and avoids dictionary words.

Is my password sent anywhere when I generate it?

No. The password is created entirely in your browser using the Web Crypto API. Nothing is transmitted or stored, so you can safely use it for real accounts.
