Password Generator은(는) 무엇을 하나요?
Password Generator은(는) 브라우저에서 결과 생성을(를) 수행하며 결과와 제한을 명확히 설명합니다. 검증된 기능: Web Crypto random source, 8 to 128 characters, Required set coverage, Entropy estimate.
Prefer length and uniqueness
Use a unique random password of at least 16 characters when supported. Store it in a password manager and enable multi-factor authentication as a separate control.
사용 방법
- Choose a length of at least 16 characters when allowed.
- Select accepted character sets and exclude ambiguous characters only when manual entry matters.
- Generate and store the unique value directly in a trusted password manager.

One unique random password plus its estimated entropyThe exact output changes every run because bytes come from the browser cryptographic random source.
일반적인 오류와 해결 방법
| 현상 | 가능한 원인 | 해결 방법 |
|---|---|---|
| The service rejects the password. | Its length or allowed-character policy differs from the selected settings. | Match the destination policy while keeping as much length and character variety as possible. |
| Generated values repeat after manual edits. | A copied password was reused or modified outside the generator. | Generate and store a separate value for every account. |
Entropy is only one security control
이 도구의 구체적인 제한: The estimate assumes independent uniformly selected characters. It does not account for password reuse, phishing, malware, reset weakness, storage, or service-side hashing.

Password Generator — FAQ
Are passwords generated on a server?
No. crypto.getRandomValues runs in the browser and generated values are not sent to KitLumi.
How long should a password be?
Use at least 16 random characters for ordinary accounts when the service permits it.
What does entropy estimate?
It estimates the random search space and does not measure storage, phishing, malware, reset, or reuse risk.
변경 사항
실질적인 업데이트: Password Generator: Added Web Crypto generation, character-set controls, ambiguity filtering, required-set coverage, entropy estimates, bulk copy, and download.
