패스키 are a next-generation 인증 method that replaces traditional passwords with biometric or device-based verification. This 가이드 explains what 패스키 are and how to start using them.

What Are 패스키?

패스키 are a FIDO (Fast IDentity Online) standard-based 인증 method that uses public key cryptography. Instead of memorizing a 비밀번호, you authenticate using your device’s biometric sensor (fingerprint, Face ID) or PIN. The private key is stored securely on your device and never leaves it, making phishing attacks virtually impossible.

Major platforms now support 패스키. Apple introduced them with iOS 16 and macOS Ventura in 2022. Google added 패스키 support for Google Accounts in 2023. Microsoft integrated 패스키 into Windows 11 and Microsoft accounts. This widespread platform support means you can already use 패스키 across most of your devices.

Why 패스키 Are More Secure

Traditional passwords have fundamental security weaknesses: they can be guessed, stolen through phishing, intercepted in transit, or leaked in data breaches. A 2024 Verizon report found that 80% of data breaches involved compromised credentials.

패스키 eliminate these risks entirely. Since the private key never leaves your device, there is nothing for attackers to steal. Each 패스키 is cryptographically bound to a specific website or app, so phishing attacks that trick you into logging into a fake site simply will not work. Even if a service provider’s 서버 is breached, the stored public key is useless to attackers without the corresponding private key on your device.

How to Start Using 패스키

Using 패스키 is straightforward. When you log into a supported service, you will see an option like “Create a 패스키” or “Use 패스키.” After selecting it, your device will prompt you to authenticate with Face ID, Touch ID, or your system PIN. Once created, subsequent logins only require biometric verification—no passwords to type or remember.

Your 패스키 sync across your devices through your platform’s cloud service. Apple 패스키 sync via iCloud Keychain, Google 패스키 via Google 비밀번호 Manager, and Microsoft 패스키 via Windows Hello. This means you can create a 패스키 on your iPhone and use it on your Mac or iPad without any additional setup.

Summary

패스키 represent a fundamental shift in online security. By eliminating passwords entirely, they remove the most common attack vector for data breaches. Start creating 패스키 for supported services today and experience a more secure, convenient 로그인 process.
