🔐 비밀번호 생성기

암호화 보안 비밀번호 - 브라우저에서 로컬로 생성됨

🔒 이미지가 기기 밖으로 나가지 않아요. 모든 처리는 Web Crypto API (crypto.getRandomValues)를 사용하여 브라우저에서 로컬로 이루어져요. 업로드, 서버, 추적이 없어요.

기능

  • Cryptographically Secure — Uses the Web Crypto API for truly random generation — not pseudo-random.
  • Customizable Rules — Control length, character sets (uppercase, lowercase, numbers, symbols), and exclude ambiguous characters.
  • Strength Meter — See password strength rating and entropy bits to gauge security level.
  • Fully Offline — Passwords are generated locally. Nothing is transmitted or stored.

작동 방식

  1. Set your rules — Choose password length and toggle character sets (uppercase, lowercase, numbers, symbols).
  2. Generate passwords — Click Generate for one password or Generate 5 for a batch.
  3. Copy and use — Copy the password to your clipboard. Check the strength meter for security assurance.

활용 사례

  • Create strong passwords for online accounts
  • Generate API keys and secret tokens for development
  • Bulk-generate temporary passwords for team onboarding

자주 묻는 질문

How secure are the generated passwords?

Very secure. We use crypto.getRandomValues() which provides cryptographically strong randomness. A 16-character password with all character sets has over 100 bits of entropy.

What does 'Exclude Ambiguous' do?

It removes characters that look similar: 0/O, 1/l/I. This prevents confusion when reading or typing passwords manually.

Are the passwords stored anywhere?

No. Passwords exist only in your browser session. Once you close the tab, they are gone.
