Abstract: The subject technology provides a framework for a trusted device to modify a security state of a target device (e.g., not fully unlocking the target device by activating biometric authentication at the target device) based on a secure ranging operation. The subject technology enables the trusted device to establish a secure and authenticated connection with the target device that is used to activate biometric authentication at the target device. The biometric authentication may fully unlock the target device. The trusted device may be able to activate the biometric authentication at the target device when the trusted device is in an unlocked state, or even when the trusted device is in a locked state so long as less than a threshold amount of time has passed since the trusted device was last unlocked.
