✳️ Highlights

• Readable & phone-friendly: simple words + punctuation + digits
• Meets most policies: uppercase + lowercase + digits + . or - punctuation
• Configurable length: dropdown 12–20 (default 15)
• Crypto-random: uses the browser’s Web Crypto API
• Client-side only: runs entirely in the browser — no data is sent
• Copy to clipboard: click any generated phrase (visual confirmation)
• Accessible UI: keyboard support, ARIA roles, high contrast
• Customizable word lists: edit arrays in the source

🔐 Policy & Security Notes

• First word is always capitalized (e.g., Blue-…) for clarity and to satisfy common “has uppercase” rules.
• Punctuation is . or - (chosen per phrase), typically counted as special characters in modern policies.
• A 3–4 digit integer (no leading zero) is appended.
• A conservative “Over X unique phrases at N+ chars” estimate is shown and updates with the Minimum characters selection.

This tool is designed for temporary password resets and short-term access — not as a long-term master password manager.

---

🧩 How It Works

• Start with Color + Object
• Choose one separator for the whole phrase: . or -
• Add 3 digits; if the Minimum characters requirement isn’t met, use 4 digits; if still short, add another Object
• Filter phrases containing banned substrings or banned numbers (customizable)

---

🔧 Customize

Open simple-password-generator.html and edit:

• Word lists: COLOR, ANIMALS, VEGETABLES, MINERALS
• Banned substrings / numbers: BANNED_SUBSTRINGS, BANNED_NUMS
• Default minimum characters: set the <select> default option
