Anyone who needs a strong, unique password for an account, Wi-Fi, or device.

How to use the Password Generator

  1. Type your values into the fields above — pick your currency or units where the calculator offers them.
  2. Results update automatically as you type; there's no submit button and nothing is sent to a server.
  3. Adjust any input to compare scenarios, then copy the result with a single click.

How it works

Characters are drawn from your selected sets using your browser's cryptographic random generator, guaranteeing at least one of each chosen type, then shuffled. More length and more character types mean higher entropy.

Features

  • Adjustable length (4–128)
  • Upper, lower, numbers, symbols
  • Entropy & strength shown
  • Cryptographically random

What makes a password strong?

Strength comes from length and unpredictability, measured in bits of entropy. A long password drawn from a large character pool is exponentially harder to guess than a short one. This generator uses cryptographic randomness in your browser, so each password is unique and never transmitted. Pair it with a password manager to store them.

Frequently Asked Questions

Are these passwords safe to use?

Yes — they're generated locally with your browser's cryptographic random generator and never leave your device. Store them in a password manager.

How long should my password be?

Aim for at least 12–16 characters with mixed types. Longer is always stronger; 20+ is ideal for important accounts.

Is this calculator free and private?

Yes. It's completely free with no signup, and every calculation runs locally in your browser, so your numbers never leave your device.
