What is Password Generator?

Strong password generator to create cryptographically secure random passwords directly in your browser.

Unlike online password generators that might log or transmit the passwords they create, this tool generates everything locally using JavaScript - your passwords are never sent to any server, never logged, and never stored. Choose the password length (4 to 64 characters) and select which character types to include: lowercase letters, uppercase letters, numbers, and special symbols. Generate up to 20 passwords at once in a bulk batch and see a strength meter for each. Use it as a 16 character password generator, a passphrase generator, or an API key and secure token generator for new accounts, password resets, or wifi credentials. Works fully offline once loaded, with no ads and no tracking. No signup, completely private and client side.

How to Use Password Generator

2Choose which character types to include by toggling lowercase, uppercase, numbers, and symbols on or off
3Select how many passwords to generate at once, from 1 to 20
4Click 'Generate Passwords' to create your passwords, then click the copy button next to any password to copy it

Frequently Asked Questions

How secure are the generated passwords?

Very secure. The passwords are generated using cryptographically secure random number generation in your browser. Each password is completely random with no patterns, making them resistant to brute-force and dictionary attacks.

What makes a strong password?

A strong password is at least 12 characters long and includes a mix of lowercase letters, uppercase letters, numbers, and special symbols. Avoid using common words, personal information, or predictable patterns. This tool generates passwords that meet all these criteria by default.

Are the passwords stored or sent anywhere?

No. Every password is generated entirely in your browser using JavaScript. Nothing is transmitted to any server, nothing is logged, and nothing is stored. Once you leave the page, the passwords exist only where you saved them.

How long should my password be?

For most accounts, 16 characters or longer is recommended. For highly sensitive accounts (banking, email, password managers), use 20 characters or more. Longer passwords exponentially increase the time needed for brute-force attacks.

Why should I trust this password generator over others?

Many online password generators send generated passwords to a server or could potentially log them. ToolBox generates passwords entirely client-side in your browser using JavaScript. No network requests are made during generation, so your passwords are never exposed to any external system.

Can I generate multiple passwords at once?

Yes. You can generate up to 20 passwords at once, each with the same length and character settings. This is useful when you need to create passwords for multiple accounts or generate a batch of API keys.

What character types can I include?

You can include lowercase letters (a-z), uppercase letters (A-Z), numbers (0-9), and special symbols (!@#$%^&* etc). You can toggle each type on or off. For maximum security, enable all four types.

Can I use this to generate API keys or tokens?

Yes. Set the length to 32 or 64 characters and include letters and numbers. The output is a cryptographically random string that works well as an API key, secret token, or session identifier. Since generation happens locally, the keys are never exposed.

Can I generate a password without special characters?

Yes. Turn off the symbols toggle to produce passwords using only letters and numbers. This is useful for systems that reject special characters, such as some wifi routers or legacy login forms.

Does the generator work offline?

Yes. Once the page has loaded, generation runs entirely in your browser and needs no network connection. You can disconnect from the internet and the tool will keep producing secure passwords.
