1. A method at a wearable device, comprising:
determining a physiological profile associated with an identity of a user over a period of time;
determining, by the wearable device, that the user is wearing the wearable device on a finger of the user based at least in part on a disruption of light detected by a photodetector;
collecting physiological data from the user based at least in part on determining that the user is wearing the wearable device;
scaling the collected physiological data to compensate for an impact of one or more biological rhythms on the collected physiological data wherein the impact is relative to the period of time associated with the physiological profile;
normalizing the scaled physiological data based at least in part on one or more differences between the scaled physiological data and the physiological profile in accordance with an activity being performed by the user, a condition associated with the user, or both;
determining the identity of the user based at least in part on the normalized physiological data matching the physiological profile associated with the identity; and
authenticating the user for an action by the wearable device that requires user authentication based at least in part on the normalized physiological data matching the physiological profile associated with the identity.
