Quick answer

A password generator creates strong random passwords for your accounts. YaliKit builds each one in your browser with crypto.getRandomValues, the browser's cryptographically secure random source, so nothing is ever sent to a server. You can make random strings or memorable passphrases, see live entropy and crack-time, exclude look-alike characters, and bulk generate up to 100 at once.

Why Use Password Generator?

Generated in Your Browser, Never Sent Anywhere

Every password is made on your device with crypto.getRandomValues, the browser's cryptographically secure random source. Turn off your wifi and it still works. There's no server to trust, log, or leak - check the Network tab and you'll see zero requests.

Passwords and Memorable Passphrases

Switch to passphrase mode for a string of random real words (Diceware / EFF style) that's easy to remember and type but still very strong. Pick the word count, separator, and whether to capitalize or add a number.

Live Strength and Crack-Time

See the exact entropy in bits and how long an offline attacker would need to crack it, updating as you change the options. Because we generated it, the entropy is exact - no guessing.

Bulk Generate up to 100

Need a batch for a team, seed data, or a stack of wifi keys? Generate up to 100 at once and download them as a text file - something almost no other free generator offers.

Common Uses

New Accounts

A unique strong password for every signup.

Teams & Seeding

Bulk-generate a batch and download them.

WiFi Keys

A memorable passphrase guests can actually type.

Password Managers

Long random master passwords and account logins.

How It Works

1

Choose Password or Passphrase

Password mode gives you a random string; passphrase mode gives you memorable random words. Pick whichever fits.

2

Set Your Options

Adjust the length or word count, toggle character types, exclude look-alike characters (O 0 l 1 I), or ban repeats and sequences. The strength meter updates live.

3

Copy or Generate a Batch

Copy the result with one click, hit Generate for a new one, or switch to bulk to make up to 100 at once and download them.

Pro Tips

Length Beats Complexity

A longer password is stronger than a short one crammed with symbols. Drag the length up and watch the crack time jump.

Use a Passphrase for Things You Type

For a wifi key or a master password you type often, a five or six word passphrase is both strong and easy to enter.

One Unique Password per Account

Never reuse passwords. Generate a fresh one for every account and store them in a password manager.

Frequently Asked Questions

It's safe when the generator runs entirely in your browser and never sends the password anywhere - which is exactly how this one works. It uses crypto.getRandomValues (the browser's cryptographically secure random source) and makes zero network requests. You can verify this in your browser's Network tab, or just turn off your wifi and it still works.
No. Nothing is uploaded, stored, or logged. The whole tool is client-side JavaScript, so the passwords only ever exist in your browser until you copy them.
For everyday accounts, 16 characters with a mix of types is strong. For critical accounts (email, banking, password manager), use 20 or more. Length matters more than complexity, so a longer password of only letters can beat a short one full of symbols - the strength meter shows the exact trade-off.
A passphrase is several random real words joined together, like 'brave-cloud-eagle-frost'. It's much easier to remember and type than a random string, and with five or more words from a large list it's very strong (each word adds about 13 bits of entropy). Passphrase mode here uses the EFF long word list.
With crypto.getRandomValues, the browser's cryptographically secure pseudo-random number generator, using rejection sampling so there's no bias toward certain characters. It does not use Math.random, which is predictable and unsafe for passwords.
Yes. Once the page has loaded, it needs no internet - everything runs locally. You can disconnect and keep generating.
Symbols add strength and are a good default. But some sites reject certain symbols, so you can turn them off, or use 'exclude custom characters' to remove just the ones a site won't accept. The strength meter shows how much turning symbols off costs you.
From the exact entropy (length times the log base 2 of the character-pool size, or word count times log2 of the word-list size). We assume a fast offline attacker at about 100 billion guesses per second and show the expected time to find it, which is half the keyspace.
