While 패스키 are designed to be reliable, you may encounter issues. This troubleshooting 가이드 covers common problems and their solutions.

패스키 Not Syncing Across Devices

If a 패스키 created on one device does not appear on another, check that you are signed into the same cloud 계정 on both devices. For Apple, verify iCloud Keychain is enabled. For Google, confirm Chrome sync is active. For Microsoft, check your Microsoft 계정 sync 설정.

If sync is enabled but still not working, try manually refreshing: toggle sync off and on, or sign out and sign back into your 계정. In some cases, a device restart resolves sync delays.

Biometric 인증 Failing

If Face ID or fingerprint recognition does not work, clean the sensor and your fingers or face. Ensure proper lighting for facial recognition. Check that biometric 설정 are enabled in your device’s security 설정. On iPhone, go to 설정 > Face ID & Passcode. On Android, 설정 > Security > Biometrics.

If hardware issues persist, most devices allow PIN or 비밀번호 fallback even when biometrics fail. In enterprise environments, IT policies may restrict biometric options.

Website or App Does Not Support 패스키

Many sites still do not support 패스키. In this case, the 패스키 option simply will not appear. Continue using your 비밀번호 manager for these sites. Check the service’s help documentation or security 설정 periodically for new 패스키 support.

You can also encourage services to add 패스키 support by providing feedback through their support channels.

QR Code 패스키 Transfer Not Working

When using cross-device 패스키 transfer via QR code, ensure both devices have 블루투스 enabled. Hold them close together during the transfer. Make sure the camera on the device scanning the QR code is not obstructed. Check that both devices have up-to-date operating system 버전.

패스키 Prompt Not Appearing

If a service supports 패스키 but the prompt does not appear, try using a supported browser. Safari (Apple), Chrome (Google), and Edge (Microsoft) have the best 패스키 support. Some browsers or browser extensions can interfere with WebAuthn—try disabling extensions temporarily.

Clearing browser cache or restarting the browser can also resolve this issue.

계정 Locked After Device Loss

If you lose your device without 설정 up recovery options, 계정 recovery can be difficult. Contact the service’s support team and be prepared to verify your identity through alternative means (email, phone verification, security questions). This process varies by service and can take days.

This underscores the importance of configuring recovery methods before relying solely on 패스키.

Summary

Most 패스키 issues have straightforward solutions. Keep your software updated, ensure proper sync 설정, and always configure recovery options before switching to 패스키-only 인증.
