비밀번호는 하나만 기억하면 됩니다. 비밀번호 관리자의 작동 방식, 현재 사용 중인 것보다 안전한 이유, 그리고 어떤 것을 선택해야 하는지는 다음과 같습니다.
대부분의 사람들이 비밀번호를 처리하는 방식의 문제점
- The average person reuses the same 2–3 passwords across dozens of sites. When one site gets hacked — and they do, constantly — attackers try those same passwords everywhere else. This is called a credential stuffing attack.
- In 2024 alone, over 10 billion unique login credentials were leaked in a single database dump.
- The solution is a unique, strong password for every site. The problem is that's impossible to remember. That's exactly what a password manager solves.

비밀번호 관리자의 작동 방식
- You create one strong master password. The password manager uses that to encrypt a vault containing all your other passwords.
- When you visit a site, it automatically fills in the correct username and password. You never type or remember it.
- When you create a new account, it generates a random, unguessable password (e.g.
xK9#mPqL2$vNrY7j) and saves it immediately. - Your vault is encrypted on your device before it's synced to the cloud. Even the company can't read your passwords.
어느 것을 사용해야 합니까?
- Bitwarden is our top pick. It's open-source (anyone can audit the code), has a generous free tier, works on every device and browser, and costs $10/year for premium features you probably don't need yet.
- 1Password is polished and family-friendly, but costs $3/month. Worth it if you want to share passwords with a partner or household.
- Apple Keychain is built into every iPhone and Mac. If you never use Windows or Android, it works perfectly and costs nothing.
시작하는 방법
- Install Bitwarden and create an account. Pick a strong master password you'll actually remember — something like a phrase from a song plus a number and symbol.
- Install the browser extension. From now on, every time you log into a site, Bitwarden will offer to save the password. Say yes.
- Over the next few weeks, as you naturally log into your accounts, Bitwarden builds your vault. You don't need to do it all at once.
