Selection of authentication function according to environment of user device

A user device, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• detect an authentication event associated with unlocking the user device;
• determine, based at least in part on sensor data, an environmental context of the user device;
• determine whether to select, from a plurality of authentication functions of the user device, a facial recognition authentication function based at least in part on the environmental context of the user device,
• wherein the environmental context indicates one or more of:
• whether the user device is still or in motion,
• an amount of ambient light surrounding the user device,
• an orientation of the user device, or
• a position of a finger relative to a fingerprint sensor;
• and
• activate, based on a determination of whether to select the facial recognition authentication function, an authentication component to authenticate a user in association with unlocking the user device.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a user device, cause the user device to:
• detect an authentication event associated with unlocking the user device;
• determine, based at least in part on sensor data, an environmental context of the user device;
• select, from a plurality of authentication functions of the user device, a facial recognition authentication function based at least in part on the environmental context of the user device,
• wherein the environmental context indicates one or more of:
• whether the user device is still or in motion,
• an amount of ambient light surrounding the user device,
• an orientation of the user device, or
• a position of a finger relative to a fingerprint sensor;
• and
• activate an authentication component based on selecting the facial recognition authentication function.

An apparatus, comprising:

• means for detecting an authentication event associated with unlocking a user device that includes the apparatus;
• means for determining, based at least in part on sensor data, an environmental context of the user device;
• means for selecting, from a plurality of authentication functions of the user device, a facial recognition authentication function based at least in part on the environmental context of the user device;
• and
• means for activating an authentication component that is associated with the facial recognition authentication function to authenticate a user in association with unlocking the user device.
