Strong Password Generator
Password Rangers is a free strong password generator that runs completely in your browser. Every password comes from the Web Crypto API, the same cryptographic randomness that protects encryption keys. Nothing is sent to a server, saved, or logged. No account, no limits, and it keeps working offline.
Need something specific? Try the passphrase, PIN, or Wi-Fi generator.
How to create a strong password here
Two settings and a copy button. That is the whole workflow.
- 1
Set the length
Sixteen characters is a sensible floor for important accounts. The preset chips jump straight to 16, 20, or 32.
- 2
Pick a strength preset
Hard mixes letters, numbers, and symbols. Medium drops the symbols for picky sites. Easy keeps codes readable for typing out.
- 3
Copy it into a password manager
Press copy and save the password in a manager right away. Every account should get its own, so generate freely.

How it compares with a typical generator
Plenty of sites will hand you a random string and a green bar. Here is what this one does differently, feature by feature.
Every password type in one place
Random passwords, word based passphrases, PINs, Wi-Fi keys with QR codes, and bulk lists. Most generators stop at the first one.
Honest strength math
No vague green bar. You see the exact entropy in bits and how long a rig testing 10 billion guesses per second would need, updating live as you change settings.
Nothing to sign up for
Most online generators exist to introduce a subscription. This one is just the tool, free, with nothing to join and nothing pushed on you.
| Feature |  | Typical generator |
|---|---|---|
| Random character passwords | Yes | Yes |
| Memorable passphrases | Yes | sometimes |
| Numeric PIN mode | Yes | rare |
| Entropy shown in bits, with crack time | Yes | basic bar |
| Wi-Fi QR code sharing | Yes | No |
| Bulk generate up to 1,000 with export | Yes | No |
| Strength test for your own password | Yes | rarely |
| Works offline once loaded | Yes | varies |
| Pushes a paid product or sign-up | No | Yes |

The safest password is one that never travels.
A generator that sends your password over the network asks for your trust. This one removes the question entirely, because nothing ever leaves your machine.
Generated on your device
Once this page loads, everything happens in your browser. Switch off your internet connection and the generator keeps working exactly the same.
Real cryptographic randomness
Every character comes from the Web Crypto API (crypto.getRandomValues) with rejection sampling to remove bias. The predictable Math.random() is never used.
Nothing leaves, nothing is kept
No password is sent to a server, written to disk, or saved in a cookie. The session list lives in memory and vanishes when you close the tab.
Our guidance follows NIST Special Publication 800-63B and CISA's Secure Our World program: favor length over forced complexity, never reuse passwords, use a password manager, and turn on multi-factor authentication.
// unbiased integer in [0, max) with no Math.random()
function secureRandomInt(max) {
const range = 0x100000000; // 2^32
const maxValid = range - (range % max);
const buf = new Uint32Array(1);
let x;
do {
crypto.getRandomValues(buf); // Web Crypto
x = buf[0];
} while (x >= maxValid); // reject bias
return x % max;
}Is your password strong enough? Test it.
Type any password to estimate its entropy and how quickly an attacker could crack it. Like everything on this site, the check runs on your device, and what you type never leaves this page.
- Length beats complexity. A long passphrase outlasts a short scramble of symbols.
- Never reuse a password across sites. One breach should never unlock the rest.
- Keep passwords in a password manager, not in a notes app or on a sticky note.
Estimate only. Real attackers also try dictionaries, leaked password lists, and personal details. When in doubt, generate a fresh one above.
How long should a password be?
Sixteen characters or more. NIST Special Publication 800-63B recommends at least 15 characters for accounts protected by a password alone, and CISA's Secure Our World program suggests 16 or longer. Length matters more than any other setting, because each added character multiplies the attacker's work.
The table shows how long a brute force attack would take against fully random passwords using letters, numbers, and symbols, assuming offline hardware testing 10 billion guesses per second. Read the full breakdown in our guide, how long should a password be.
| Length | Entropy | Time to crack |
|---|---|---|
| 8 characters | 51 bits | about 2 days |
| 12 characters | 77 bits | about 259,000 years |
| 16 characters | 103 bits | about 14 trillion years |
| 20 characters | 129 bits | longer than the universe has existed |
Estimates use the same math as the meter above: character pool of 86, average case, 10 billion guesses per second.
Questions? Say less.
Is it safe to use an online password generator?
Yes, as long as the generator runs in your browser instead of on a server. This one creates every password locally with the Web Crypto API and makes zero network requests while doing it, which you can confirm in your browser's developer tools. Nothing is transmitted, stored, or logged.
Should I ask ChatGPT or another AI chatbot for a password?
No. Chatbots draw from a small pool of patterns rather than true randomness. In research published in February 2026, one leading AI model returned only 23 unique passwords across 50 requests. Use a generator built on cryptographic randomness instead, then keep the result in a password manager.
How long should a password be?
Use at least 16 characters for anything that matters. NIST guidance now recommends a 15 character minimum for accounts protected by a password alone, and CISA suggests 16 or more. A 16 character password from this tool carries about 103 bits of entropy, far beyond practical brute force.
What is the strongest type of password?
A long, fully random one. A 20 character password mixing letters, numbers, and symbols holds about 129 bits of entropy, which no known hardware could brute force. If you need to remember it without a manager, a six or seven word random passphrase is the strongest practical choice.
How does this password generator work?
It asks your browser's Web Crypto API for cryptographically secure random values, then maps them onto the character sets you picked, using rejection sampling so every character has exactly the same chance of being chosen. The code runs on your device, so the password only ever exists on your screen and clipboard.
Is this password generator really free?
Yes. Every tool on this site is free, with no account, no email, no trial, and no paid tier. Generate one password or a thousand. Nothing you create ever reaches us, so there is nothing for us to sell or gate.
Do you store or see the passwords I create?
No. Passwords are generated on your device and never leave it. The generator makes no network requests, sets no password related cookies, and keeps the session list in memory only, so it disappears when you close the tab. We could not see your passwords even if we wanted to.
What is a good example of a 16 character password?
Something like V$k9wQz2#mL7pR4t, where every character is chosen at random from letters, numbers, and symbols. Never use an example you saw online, including that one. Set the length to 16 above and press generate to get your own, with about 103 bits of entropy.
Which is better, a password or a passphrase?
For pure strength per character, random passwords win. For anything you type by hand or must remember, like a laptop login or your password manager's master password, a passphrase of five to seven random words is stronger in practice, because you will actually use it correctly.
Can a randomly generated password be cracked?
Not by guessing at sensible lengths. A 16 character random password would keep an offline rig testing 10 billion guesses per second busy for trillions of years. The realistic risks are phishing, malware, and reuse, so store generated passwords in a manager and turn on two factor authentication.
