    Password Generator – Create Strong Random Passwords Online Free

    Generate strong, cryptographically random passwords online. Choose length (16+ recommended), character types, and rules. Exclude look-alike characters, batch generate multiple passwords, and copy with one click. Weak or reused passwords put accounts at risk — this secure password generator helps you create unique, high-entropy credentials on demand, all in your browser without any uploads or tracking.

    The tool runs entirely in your browser, using the Web Crypto API when available for strong randomness. That means nothing is uploaded, stored, or logged. You can use it as a random password generator for one-offs, a strong password generator for sensitive accounts, or even as a lightweight password gen tool when you just need a quick secure string.

    Options include excluding look-alike characters like O/0 and l/1, requiring at least one from each selected set, and blocking adjacent repeats for easier manual typing. A built-in strength meter shows entropy in bits, so you can gauge how resistant the output is to brute-force attacks.

    Generate once or regenerate until you find one you like. Copy a single password with one click, or copy the entire batch for use in your password manager. Pair this with our Secure Text Encryptor if you need to protect notes or files with the same password hygiene.

    How to choose a strong password

    Use 16+ characters as a minimum — length is the single biggest factor in resistance to brute-force attacks. Mix all character types: uppercase, lowercase, numbers, and symbols. Never reuse passwords across accounts; a breach on one site should never compromise another. Store all your passwords in a password manager so you only need to remember one strong master password. For high-security accounts, consider using a passphrase — four or more random words strung together are both memorable and highly entropy-dense.

    Tips

    • Use 16+ characters for a strong baseline.
    • Always use a unique password per account; store them in a manager.
    • Enable 'Require all types' only when a site demands it.
    • Turn on 'Exclude look-alikes' if you’ll type passwords manually.
    • For memorable secrets, consider a long passphrase instead of a short complex string.

    Frequently asked questions

    Is this password generator safe?
    Yes. It runs locally in your browser; nothing is uploaded.
    What makes a strong password?
    Length and uniqueness. Use 16+ characters, avoid reuse. Mixing sets boosts entropy, but length matters most.
    Can I make a numeric PIN?
    Yes. Enable only Numbers and set a length. For accounts, prefer longer mixed-set passwords.
    Does the tool log or store what I generate?
    No. Nothing is uploaded or stored anywhere.
    Can I export many generated passwords?
    Yes. Use Copy all to export into a manager or secure doc.
    How do I generate a strong random password online for free?
    Set your desired length (16+ characters is recommended), enable uppercase, lowercase, numbers, and symbols, then click Generate. Copy the strong password with one click. No account needed.
    How long should a secure password be?
    For most accounts, 16 characters or more is a solid baseline. For highly sensitive accounts, 20–24 characters with mixed character types is better. Always use a password manager to store long passwords so you don't have to memorize them.
    How do I create a random password with special characters online?
    Enable the Symbols option and set your desired length. The generator includes special characters like !, @, #, $ in the output. Use the Exclude look-alikes option to avoid confusing characters like O/0 and l/1.
