About SmartPass — Smart Password Generator
SmartPass 是一款隱私優先、完全離線運作的密碼產生器。
核心差異化在於「DOM 規則自動解析」:開啟外掛時會自動偵測目前分頁密碼欄位的
minlength / maxlength / pattern 限制,自動調整產生規則,確保產生的密碼不會
被網站表單擋下來。
功能特色:
• 三種產生模式 — 隨機密碼、可發音密碼(好記好打)、Passphrase 單字組合密碼
• Smart DOM Auto-Match — 自動偵測目前分頁的密碼欄位規則並調整選項
• 即時強度提示 — 依字元集與長度即時計算熵值(bits)
• 明亮/暗色主題 — 一鍵切換,偏好僅存本機
• 一鍵填入 — 偵測到密碼欄位後可直接填入
• 剪貼簿自動清空 — 複製後 30 秒自動清空,避免密碼殘留剪貼簿
• 本機歷史紀錄 — 僅保留最近 5 筆,存於 chrome.storage.local,可一鍵清除
• 右鍵選單整合 — 在任一輸入欄位按右鍵,直接「產生密碼並填入」或「產生密碼並複製」
• 鍵盤快捷鍵 — Ctrl/Cmd+Shift+U 開啟視窗;Ctrl/Cmd+Shift+G 直接產生並複製
隱私與安全:
• 完全離線運作,程式碼中沒有任何對外部伺服器的網路請求
• 不蒐集、不回傳任何個人資料、瀏覽紀錄或產生的密碼
• 所有隨機性皆透過瀏覽器原生的 Web Crypto API(crypto.getRandomValues)產生,
不使用 Math.random()
• 不要求 <all_urls> 或任何主機權限
適合每天需要在各種網站註冊、改密碼,又想要密碼夠強、夠隨機的使用者。

SmartPass — Smart Password Generator
**Short description** (132 chars max, currently ~104)
Offline password generator that auto-detects a site's password rules and fills in a strong password with one click.
**Detailed description**
```
SmartPass is a privacy-first, fully offline password generator.
Its core differentiator is DOM rule auto-parsing: when opened, it detects the
active tab's password field minlength / maxlength / pattern constraints and
tightens generation rules automatically, so the password it generates is
never rejected by the site's own form validation.
Features:
• Three generation modes — random, pronounceable, and passphrase
• Smart DOM Auto-Match — detects the current page's password field rules
• Live strength readout — real entropy (bits), computed from the actual
character set and length in play
• Light / dark theme — one click, preference stored locally only
• Fill field — insert the generated password directly into the detected field
• Clipboard auto-clear — clears 30 seconds after copy
• Local history — last 5 entries only, stored in chrome.storage.local,
one-click clear
• Right-click menu — "Generate & fill" / "Generate & copy" on any input field
• Keyboard shortcuts — Ctrl/Cmd+Shift+U opens the popup;
Ctrl/Cmd+Shift+G generates and copies without opening it
Privacy & security:
• Runs fully offline — the code makes no network requests of any kind
• Collects and transmits no personal data, browsing history, or generated
passwords
• All randomness comes from the browser's native Web Crypto API
(crypto.getRandomValues), never Math.random()
• Requests no <all_urls> or other host permissions
