KitYards Secure Password Generator creates strong, unpredictable passwords using your browser's built-in cryptographic random generator. Choose a length from 8 to 64 characters and toggle uppercase letters, numbers and symbols to match any site's rules. Every password is generated locally and nothing is ever transmitted, stored or logged, so your credentials stay entirely on your device and known only to you.
How to use the Secure Password Generator
- 1 Set your desired password length using the slider.
- 2 Toggle uppercase letters, numbers and symbols on or off.
- 3 Click generate to create a new random password.
- 4 Copy the password and store it in a trusted password manager.
How the randomness is generated
Every character comes from crypto.getRandomValues, the browser’s cryptographically secure pseudo-random number generator. It is seeded by the operating system’s entropy pool — the same source that seeds TLS keys — and is specifically designed to be unpredictable even to someone who has seen its previous output. This matters because the obvious alternative, Math.random, is not: it is a fast statistical generator whose internal state can be reconstructed from a modest sample of its results, which would make every password it produced predictable.
The generator builds a character pool from the options you enable — lowercase letters always, plus uppercase, digits and symbols when toggled — and then draws each position from that pool. Rejection sampling is used rather than a plain modulo, so no character is slightly more likely than another; a naive modulo over a random byte quietly biases the alphabet whenever the pool size does not divide 256 evenly.
Nothing about the password is transmitted, logged, or written to storage. It exists in the page’s memory and in your clipboard if you copy it, and it is gone when you close the tab. There is no "recently generated" list to leak, because there is no list.
When to reach for it
A new account you will never type
If a password manager will store and fill it, length is free. Generate 32 characters or more with every character class enabled — you will never type it, so its awkwardness costs you nothing.
A password you must type by hand
Wi-Fi keys, device unlock codes and workstation logins get typed on phone keyboards and TVs. Turn symbols off and raise the length instead: length buys far more security than punctuation does.
API keys and seed values
A long alphanumeric string from a secure generator is a reasonable ad-hoc token for a side project or a test fixture. For production credentials, prefer whatever your platform issues natively.
Replacing a breached password
After a breach notification the reflex is to change one character. Do not — that is the first thing credential-stuffing tools try. Generate a genuinely new password and change it everywhere you reused the old one.
What makes a password secure and how this generator works
Strong passwords are long, random and unique to each account. This generator uses crypto.getRandomValues, the browser's cryptographically secure random number source, rather than the predictable Math.random, so the output is genuinely hard to guess or brute-force. You control the strength by increasing length and enabling a mix of uppercase letters, numbers and symbols, which expands the pool of possible combinations. Use it to create passwords for email, banking, social media and work accounts, or to generate secure keys and tokens. Because everything happens client-side, your new password is never sent across the internet or saved on a server. Pair each generated password with a reputable password manager so you never have to reuse or memorize weak credentials again.
What this tool does not do
A generator is one link in a chain. Here is where its responsibility ends and yours begins:
- It does not store anything. Copy the password before you close the tab, because it cannot be recovered afterwards — there is no history and no account.
- It does not check whether a password has appeared in a breach. A freshly generated random string effectively never has, but a password you typed yourself might.
- It cannot enforce a site’s rules for it. Some sites cap length at 16 characters or reject certain symbols; if a generated password is rejected, lower the length or turn symbols off and generate again.
- It does not measure strength against a dictionary. The strength shown is based on length and pool size, which is the correct measure for random output but would flatter a human-chosen password.
- It is not a password manager. Generating strong passwords only helps if you also stop reusing them, and that needs somewhere to keep them.
Troubleshooting
- The site rejected my password
- Almost always a length cap or a symbol blacklist. Banks are the usual offenders — some still cap at 12 to 16 characters and reject anything outside a short symbol list. Turn symbols off, set the length to the site’s maximum, and generate again.
- Copy did not work
- The clipboard API needs a secure context and, in some browsers, a direct user gesture. If the copy button fails, the password stays selectable — select it and press Ctrl+C (Cmd+C on a Mac). Nothing is lost.
- I generated a password and lost it
- It cannot be recovered. Nothing is stored on your device or ours by design, which is the same property that makes the tool safe to use for real credentials. Generate a new one and save it this time before navigating away.
Frequently Asked Questions
Are the generated passwords safe to use?
Yes. Passwords are created with crypto.getRandomValues, a cryptographically secure random generator, and never leave your browser. Nothing is transmitted or stored, so no server ever sees the password you create for your accounts.
How long should my password be?
Longer is stronger. Aim for at least 16 characters and include uppercase letters, numbers and symbols. For high-value accounts like email and banking, choose 20 or more characters to dramatically increase resistance to brute-force attacks.
Can KitYards see the passwords I generate?
No. The entire process runs locally in your browser with no network requests. We never receive, log or store your passwords, so only you ever know what was generated on your device.
How long should a password actually be?
For anything stored in a password manager, 20 characters or more with mixed classes is comfortably beyond brute-force reach for the foreseeable future. For something you type regularly, 16 characters without symbols is both easier and stronger than 10 characters with them — length dominates every other factor.
Are symbols really necessary?
They help, but less than people assume. Adding symbols expands the pool from 62 to about 94 characters, worth roughly 0.6 extra bits per character. Adding four more characters to the length is worth far more, and costs you nothing in typing pain if a manager fills it.
Is a random string better than a passphrase?
Per character, yes; per unit of human effort, often no. Four or five genuinely random words are easy to remember and can be very strong, which is why they are recommended for the handful of passwords you must memorise — your device login and your password manager’s master password. Use random strings for the hundreds you should never memorise.
Could the generated password be sent somewhere without me knowing?
You can verify that it is not. Open your browser’s developer tools, switch to the Network tab and generate a password: no request is made. The page has no server endpoint to send it to — it is static HTML with a script that runs locally.
Can two people get the same password?
In theory yes, in practice never. A 16-character password drawn from a 94-character pool has about 10^31 possibilities; collisions at that scale do not happen by chance. The randomness is drawn per device from the operating system, not from a shared seed or a server.
