1. A method of authenticating a user of a first device, the method comprising:
obtaining, at the first device from a second device, at least a portion of input biometric data associated with a person;
determining a similarity score for the input biometric data by comparing the input biometric data to one or more templates, the one or more templates including reference biometric data associated with the user;
comparing the similarity score to a learning threshold; and
based on a determination that the similarity score is less than the learning threshold, updating at least one template of the one or more templates for the user to include features of the input biometric data.
