密碼產生器
建立強大的隨機密碼來保護您的帳戶！
密碼產生器是什麼？
The Password Generator creates strong, random passwords that are virtually impossible to crack through brute force attacks. In an era of frequent data breaches, using unique, complex passwords for each account is one of the most important steps you can take to protect your digital security. A typical 8-character password with only lowercase letters can be cracked in minutes, while a 16-character password mixing uppercase, lowercase, numbers, and symbols would take billions of years with current technology. Password strength increases exponentially with length and character variety. This tool generates cryptographically secure random passwords entirely in your browser. Customize length, character types, and exclusion rules to meet any website's password requirements. No passwords are stored or transmitted — everything happens locally on your device.

常見問題
▶這些密碼安全嗎？
是的！密碼使用瀏覽器的加密亂數產生器（crypto.getRandomValues）產生。沒有密碼會被傳送到任何伺服器。
▶什麼讓密碼更強？
強密碼至少 12 個字元，包含大寫字母、小寫字母、數字和符號的組合。
▶我的密碼會被儲存嗎？
不會。一切都在您的瀏覽器中執行。您的密碼永遠不會被傳輸或儲存。
▶How long should my password be?
At minimum 12 characters, ideally 16 or more. Each additional character exponentially increases security. A 16-character mixed password is virtually uncrackable with current technology, while an 8-character password can be broken in hours.
▶Should I use a different password for every account?
Yes, absolutely. If one service is breached and your password is exposed, reused passwords give attackers access to all your other accounts. Use a password manager to store unique passwords for each service.
▶Are generated passwords stored anywhere?
No. Passwords are generated using your browser's built-in cryptographic random number generator and are never sent to any server. Once you close or navigate away from the page, the generated password exists only where you copied it.
