Password Generator

Create a random password with the length and character sets you choose, from 4 to 128 characters. A strength meter scores the result and tells you what to change. The generator runs inside your browser, so the password never travels over the network.

Frequently Asked Questions

Is the password sent anywhere?

No. Generation happens in the page on your own device, the result is written into a read-only field, and copying it puts it on your clipboard. There is no upload step and no account to create.

What makes a password weak even when it is random?

Short length, a small character pool, and reuse. A fresh 12-character string is strong until it is used on three sites; then one breach exposes all three accounts. Generated once per account, the same string stays useful.

How do I store the password once it is generated?

Put it straight into a password manager and let the manager fill it in later. If you have no manager, write it down on paper and keep it somewhere physical rather than reusing a password you already know by heart.

Should I use a passphrase instead of a random string?

Use a passphrase where you have to type the secret by hand, such as a password manager master password or a device login, because word sequences are easier to remember. Use a random string where a manager fills it in for you and you never type it.

Can I generate several passwords at once?

The generator draws one password at a time. Press Generate again for a new one, or reload the page for a clean slate, then copy the one you want before drawing the next.

Do I really need symbols in the password?

They help, but less than most people assume. Moving from letters and digits to the full 88-character pool at 12 characters adds about 6 bits of entropy. Adding four characters to a letters-and-digits password adds more than switching on symbols does.

How long should a generated password be?

Twelve characters from all four sets is a reasonable working floor, and 16 is better wherever the site allows it. Length multiplies the search space, so 16 characters from the full pool sit around 103 bits of entropy against roughly 78 bits at 12 characters.

Key Terms

Password manager
Software that stores unique passwords per account and fills them into login forms, removing the need for a human to memorise more than one secret.
Character pool
The set of characters the generator draws from. Lowercase alone is 26, adding uppercase and digits makes 62, and adding the symbol set makes 88.
Brute-force attack
Trying every possible password in order, or at random, until one works. Its cost grows with the pool size raised to the power of the password length.

Why Use This Tool

Nothing leaves the browser

The string is built on your device in JavaScript, shown in a read-only field, and never posted to a server, which is the whole point of not emailing a password to yourself.

One-click copy

Send the finished password to the clipboard with a single button and paste it into the signup field or the password manager vault.

Four character sets, on or off

Uppercase, lowercase, digits, and symbols switch on and off independently, which keeps the output inside the rules a stubborn signup form will actually accept.

Ideal For

%%

Free and repeatable

Draw as many candidates as you like, in any combination of settings, and copy the one that fits the account you are creating.

Fewer mistyped characters

The exclude similar switch removes the glyphs that turn into support tickets when a password is copied by hand or read over a phone.

Generated on your device

The password is assembled in the page and never transmitted, so the tool itself is not another copy of your secret sitting on a server.

A score you can act on

The strength meter reports a number and the specific change it wants, so a weak result tells you what to fix instead of just refusing it.

$

Built for the signup form

Turn sets on and off to match a site that rejects symbols or caps length, and get a password that passes the validation rules on the first try.

The length you actually need

Set 16 characters when the policy allows it and 64 when you need a long secret for a service account, without hunting for another tool.
