Extended Password Generator: Create Strong, Custom Passwords Fast
What it is
A tool that generates long, high-entropy passwords tailored to user needs — length, character sets, patterns, and policy constraints — so you get secure, usable credentials quickly.
Key features
- Custom length: Generate very short to very long passwords (e.g., 8–64+ characters).
- Character options: Include or exclude uppercase, lowercase, digits, symbols, and ambiguous characters.
- Pronounceable / passphrase modes: Create memorable passphrases or fully random strings.
- Pattern & policy rules: Enforce required character classes, prohibit repeated characters, or match organizational password policies.
- Batch generation: Create multiple unique passwords at once for provisioning accounts.
- Entropy estimate: Show bits of entropy and an estimated time-to-crack under common attack models.
- Export & copy: Download CSV, copy to clipboard, or output in formats for password managers.
- Security options: Offline mode, avoid storing generated passwords, and optional clipboard auto-clear.
How it helps
- Produces passwords that resist brute-force and dictionary attacks.
- Balances security and usability with passphrase/pronounceable modes.
- Saves time when provisioning many accounts or meeting strict policy requirements.
Usage tips
- Prefer longer passphrases (4+ random words) for memorability, or 16+ random characters for machine-only secrets.
- Disable ambiguous characters (l, I, 0, O) for readability in printed/typed contexts.
- Use batch mode to rotate credentials and import into a password manager immediately.
- Keep generation offline when creating high-value credentials.
Example settings
- High-security machine password: 20 characters, upper+lower+digits+symbols, no ambiguous, entropy shown.
- Memorable passphrase: 5 random words from a large wordlist, optional separator.
Security note
Always store generated passwords in a reputable password manager; avoid reusing passwords across accounts.
