Have I Been Pwned - Password Breach Check

Check if a password has appeared in known data breaches. You can check any password, not just the ones generated above.

Your password is never transmitted. Only the first 5 characters of the SHA-1 hash are sent to the Have I Been Pwned API using k-Anonymity. Your actual password never leaves your browser.

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 and see a strength indicator for each. Use it for creating passwords for new accounts, resetting old weak passwords, or generating API keys and tokens. No signup, no tracking, completely private.

How to Use Password Generator

1Set the desired password length using the slider, from 4 to 64 characters (16+ recommended for most accounts)
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

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.

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.

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.

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.

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.

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.

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.

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.
