Password Generator

Generate strong random passwords using cryptographically secure randomness. Control length, symbols, numbers and ambiguous characters.

The Password Generator creates strong random passwords using the browser's cryptographically secure random number source, rather than a predictable pseudo-random function. You control the length and which character types to include — uppercase, lowercase, numbers and symbols — and can exclude ambiguous characters like 0, O, l and 1 that are easy to misread.

Because generation happens locally using the crypto.getRandomValues API, passwords are never transmitted or logged anywhere, making this suitable for generating credentials for sensitive accounts. Adjust the length slider up to cover anything from a quick PIN-style code to a long passphrase suitable for a master password vault.

How to use the Password Generator

1. Set the desired password length using the slider or input field.
2. Toggle which character types to include: uppercase letters, lowercase letters, numbers and symbols.
3. Enable the option to exclude ambiguous characters if the password will be typed manually.
4. Click generate to produce a new random password.
5. Copy the password to your clipboard and paste it directly into your password manager or account signup form.

Why use this tool

Cryptographically secure randomness

Passwords are generated using crypto.getRandomValues rather than Math.random, which produces output that is statistically unpredictable and suitable for real security use rather than simple randomisation.

Full control over composition

Length and character set toggles let you meet specific site requirements, whether that's a minimum length, mandatory symbols, or a policy that disallows certain character types.

Ambiguous character exclusion

Turning off characters that look alike, such as 0 and O, or l and 1, makes a generated password easier to type accurately when it must be entered manually rather than pasted.

Common use cases

• Generating a new unique password for every online account instead of reusing the same one.
• Creating a master password strong enough to protect an entire password manager vault.
• Producing a temporary password to share with a new employee that meets a strict complexity policy.
• Generating Wi-Fi router passwords that are long and random rather than a simple guessable phrase.
• Creating API keys or service credentials during development that need to be unpredictable.

How long should a password be?

At least 16 characters is a sensible baseline for important accounts, since length increases cracking time far more than adding complexity to a short password does. Every extra character multiplies the number of possible combinations an attacker would need to try.

Length vs complexity trade-off

A long password made of ordinary lowercase letters can be more resistant to brute-force attacks than a short one packed with symbols, simply because of how exponentially the possible combinations grow with each added character. This tool lets you push length up while still including full character variety for maximum resistance.

Storing generated passwords safely

A randomly generated password is only as useful as the system used to remember it — save each one in a password manager rather than a plain text file or sticky note, since a truly random string is not something anyone can reliably memorise.

Frequently asked questions

How long should a secure password be?

At least 16 characters with mixed types for important accounts. Length matters more than complexity — every extra character multiplies the time needed to crack it.

Are these passwords truly random?

Yes. They use the browser's crypto.getRandomValues API rather than Math.random, and are generated locally so they are never transmitted or logged.

Is Password Generator free to use?

Yes. Password Generator on Klipza is completely free with no account, no subscription and no watermark on your files, and there is no daily usage limit.

Are my files safe when using Password Generator?

Processing happens locally in your browser wherever technically possible, so your files are not uploaded to a server, stored or shared with third parties.

Does Password Generator work on mobile phones?

Yes. It is fully responsive and runs in any modern browser on Android, iPhone, iPad, Windows and macOS — nothing to install.
