Password Generator

Generate strong, random passwords with customizable length and character sets. Uses cryptographically secure randomness.

Your data never leaves your browser

How to Use

  1. 1

    Set the password length

    Choose your desired password length. 16 characters or more is recommended for high-security accounts.

  2. 2

    Choose character options

    Enable or disable special symbols depending on the requirements of the service you're creating a password for.

  3. 3

    Generate and copy

    Click Generate for a single password or Generate 10 for multiple options. Copy your preferred password.

What is Password Generator?

A password generator creates random strings of characters that are difficult to guess or crack. Strong passwords combine uppercase and lowercase letters, numbers, and special symbols, and are at least 12-16 characters long.

This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure pseudo-random numbers — the same source of randomness used for generating encryption keys in your browser. This is significantly more secure than Math.random().

Using unique, randomly generated passwords for each account is one of the most effective security practices. Combined with a password manager, it eliminates the risk of password reuse, dictionary attacks, and pattern-based guessing.

FAQ

How secure are these passwords?
Very secure. A 16-character password using lowercase, uppercase, digits, and symbols has about 96^16 (approximately 5.2 × 10^31) possible combinations. At 1 billion guesses per second, it would take over 1.6 trillion years to brute-force.
Is the randomness truly random?
Yes. The tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure pseudo-random numbers sourced from your operating system's entropy pool.
Why can't some sites accept my generated password?
Some websites have restrictive password policies — maximum length, no special characters, or specific character requirements. Adjust the length and symbol options to match their requirements.
