            "description": "An adversary with physical access to a mobile device may seek to bypass the device's lockscreen.\n\n### Biometric Spoofing\nIf biometric authentication is used, an adversary could attempt to spoof a mobile device's biometric authentication mechanism(Citation: SRLabs-Fingerprint)(Citation: SecureIDNews-Spoof)(Citation: TheSun-FaceID).\n\niOS partly mitigates this attack by requiring the device passcode rather than a fingerprint to unlock the device after every device restart and after 48 hours since the device was last unlocked (Citation: Apple-TouchID). Android has similar mitigations.\n\n### Device Unlock Code Guessing or Brute Force\nAn adversary could attempt to brute-force or otherwise guess the lockscreen passcode (typically a PIN or password), including physically observing (\"shoulder surfing\") the device owner's use of the lockscreen passcode. \n\n### Exploit Other Device Lockscreen Vulnerabilities\nTechniques have periodically been demonstrated that exploit vulnerabilities on Android (Citation: Wired-AndroidBypass), iOS (Citation: Kaspersky-iOSBypass), or other mobile devices to bypass the device lockscreen. The vulnerabilities are generally patched by the device/operating system vendor once they become aware of their existence.",
