關於 密碼產生器

產生安全隨機密碼

Long, unique passwords are easier to protect when stored in a password manager and paired with multi-factor authentication. Generation is only one part of the workflow: the service receiving the password still needs secure storage and recovery controls.

點樣用呢個開發者工具

  1. Set the desired length and character groups, then choose how many candidates to create.
  2. Exclude ambiguous characters when they could be mistyped in a manual setup.
  3. Generate a candidate, copy it directly to a password manager or test field, and clear the page when finished.

私隱同資料處理

Password generation uses browser randomness and does not intentionally send or persist generated values. Do not reuse a generated password across services or paste it into chat, logs, or source code.

常見問題

Is a generated password stored by Dev Tools?

The generator is designed to create values locally in the browser. Treat the output as sensitive and avoid saving it in browser history, screenshots, or logs.

Is a longer password better than more symbols?

Length and uniqueness are both important. Follow the receiving service's rules, prefer a password manager, and do not rely on complexity rules alone.

Can I use the generated value as an encryption key?

Only when the application explicitly defines how human-generated values become keys. Prefer a protocol's key-generation function for cryptographic material.
