Random Password Generator

Create one or more strong, random passwords with full control over length and character sets.

Password From a Word

Turn a word you'll remember (like a pet's name or a favorite place) into several strong, unique passwords.

🔒 Passwords are generated locally in your browser. Nothing is sent to our servers.

What this tool does

A strong password is still one of the simplest defenses against account takeover, credential stuffing, and brute-force attacks. FluxRadar's password generator builds long, random passwords from the character sets you choose, or turns a memorable word into several unique, secure variations, all without sending anything to a server.

Use cases

  • Create a new password when signing up for an account
  • Replace a reused or leaked password on an important account
  • Generate a batch of passwords for a team or a set of test accounts
  • Build a memorable but still strong password from a word you already know

How it works

Every password is generated in your browser using the Web Crypto API's cryptographically secure random number generator. The Random Password Generator assembles a password from your selected character sets, while Password From a Word mixes randomized capitalization, letter-to-symbol substitutions, and extra random characters into a word you provide. The page itself is served by FluxRadar, but the generation logic never leaves your device.

Benefits

Benefit
Fully adjustable length from 6 to 128 characters
Benefit
Independent control over uppercase, lowercase, numbers, and symbols
Benefit
Option to exclude visually similar characters (O, 0, I, l)
Benefit
Generate up to 10 passwords at once, each with its own copy button
Benefit
Live strength, entropy, and estimated crack-time feedback
Benefit
Runs entirely client-side — nothing you generate is transmitted anywhere

Examples

Random passwords might look like 7pR#kX2m!QzL9vDs. A word-based password built from "flux" might look like FluX@2026#7r or F1ux#R@d9P — same starting word, different strong output every time.

Documentation

Use the length slider and character-type toggles to shape a fully random password, or switch to the word-based generator to get several strong variations built from a word that's easy for you to remember. Every result includes a strength rating, an entropy estimate in bits, and a rough estimate of how long an offline attacker would need to guess it.

Frequently asked questions

  • Why do strong passwords matter? Most account breaches trace back to weak, reused, or previously leaked passwords. A long, random password with a mix of character types is far harder to guess or crack than a short word-based one, and using a unique password per account limits the damage if one site is breached.
  • Is it safe to generate passwords in a web browser? This tool generates every password locally using your browser's cryptographically secure random number generator, and no password or word you enter is sent to FluxRadar's servers.
  • What makes a password hard to crack? Length matters more than complexity alone — a 16+ character password drawn from a large character set has far more possible combinations, which is reflected in the entropy and crack-time estimates shown with each result.
  • Should I still use a password manager? Yes. A password manager lets you safely store unique, generated passwords for every account without needing to remember each one yourself.
  • What does 'exclude similar characters' do? It removes characters that are easy to confuse when typed or read, such as the capital letter O, the digit 0, the capital letter I, and the lowercase letter l.
  • How is the estimated crack time calculated? It's a rough estimate based on the password's entropy and an assumed offline guessing speed, meant to illustrate relative strength rather than serve as a precise security guarantee.
