Generate a Strong Password in One Click

Need a strong, random password right now? The generator above produces cryptographically random passwords using your browser's Web Crypto API — nothing is sent to a server, nothing is logged. Set the length, pick which character types to include, click Generate Password, and copy the result straight to your password manager.

How to Use the Password Generator

The tool above defaults to a 16-character password mixing uppercase, lowercase, numbers, and symbols — a safe baseline for almost any account. To fine-tune it:

  1. Length slider — drag from 8 up to 64 characters. Longer is stronger; 16 is the modern minimum, 20+ is ideal for anything sensitive (email, banking, crypto).
  2. Character toggles — switch off symbols if a site rejects them, or turn off numbers and symbols if you need a letter-only password for a legacy system.
  3. Copy / Regenerate — the copy button grabs the password to your clipboard; the circular arrow rerolls a new one.
  4. Strength meter — the colored bar reflects a combined score based on length and character variety. Aim for the green "Strong" band.

Every time the page loads, a fresh password is generated, so you never see the same one twice.

What Makes a Password Strong?

Strength comes from two things: length and randomness. A 16-character random string drawn from all four character types has roughly 10^30 possible combinations — brute-forcing it would take longer than the age of the universe on current hardware. A human-chosen 10-character password built around a dictionary word, a name, or a date falls to an offline cracker in seconds to hours.

The generator above always draws from crypto.getRandomValues() rather than Math.random(), so the output is cryptographically random — not just statistically random.

Password Generator vs Passphrase Generator

A password is a short-ish string of random characters (K9#mQ2vL@8xP). A passphrase is a longer string of random words (correct-horse-battery-staple). Both can be equally secure at equivalent entropy, but they optimize for different things:

  • Passwords — shorter, harder to guess per character, but also harder to type and remember. Best when stored in a password manager.
  • Passphrases — longer, easier to type on mobile or read aloud, and easier to memorize for the handful of master passwords you can't store in a manager.

If you need something you'll type by hand or commit to memory — like your password manager's master password or a device login — try the passphrase generator instead. For every other account, use this tool and let your manager remember it.

Is This Password Generator Safe to Use?

Yes. Generation happens entirely in your browser — no network request leaves your device when you click Generate Password. There's no backend, no logging, and no analytics tied to the output. Close the tab and the password is gone unless you saved it somewhere.

A few extra precautions worth taking:

  • Paste straight into your password manager. Don't leave it on the clipboard longer than needed.
  • Don't screenshot generated passwords. Screenshots sync to cloud photo libraries on most phones.
  • Regenerate if you're unsure. The button is free — when in doubt, roll a new one.

Best Practices After You've Generated One

  1. Use a password manager. 1Password, Bitwarden, and Proton Pass all autofill generated passwords without you ever needing to see or type them. This is the single biggest security upgrade most people can make.
  2. Use a unique password per account. Reused passwords turn one breach into a chain reaction. A manager makes "unique per site" effortless.
  3. Turn on two-factor authentication. A strong password stops guessing; 2FA stops credential stuffing and phishing — you want both.
  4. Only rotate passwords when there's a reason. NIST no longer recommends scheduled rotations. Change a password when a service reports a breach, when you suspect compromise, or when you've shared it — otherwise leave strong passwords alone.
  5. Avoid personal information as a fallback. Names, birthdays, pet names, and favorite teams are the first things guessers try.
