什麼是 密碼產生器?

免費線上密碼產生器。使用 Web Crypto API 建立強安全隨機密碼。自訂長度(4-64 字元),包含大寫、小寫、數字與符號。

為什麼要使用 密碼產生器?

  • Uses crypto.getRandomValues() for secure randomness
  • 可調整長度,4 到 64 個字元
  • Real-time strength indicator (weak to strong)
  • Exclude ambiguous characters (l, I, O, 0, etc.)

如何使用 密碼產生器 — 逐步教學

Set the desired password length using the slider (4-64).

2

Toggle character types: uppercase, lowercase, numbers, symbols.

3

Optionally enable "exclude ambiguous characters".

4

Click generate or copy the password directly.

密碼產生器 — 常見問題

Is this password generator secure?

Yes. Passwords are generated using the browser's crypto.getRandomValues() API, which provides cryptographically secure random numbers. No password ever leaves your browser.

What makes a strong password?

A strong password is at least 16 characters long and includes a mix of uppercase, lowercase, numbers, and symbols. Our strength indicator calculates entropy based on length and character pool size.
