1. A personal authentication method performed by a computer and comprising:
collating first biological information of a user with first registered biological information, the first biological information indicating a feature amount related to at least one of a fingerprint, an iris, a face, a voice, and a vein of the user;
allowing an application to execute based on a collating result related to the first biological information;
acquiring second biological information when the application executes, the second biological information being an external ear acoustic feature amount, by:
outputting a first signal to a device worn by the user, the first signal having a predetermined frequency;
receiving a second signal echoed in a part of body of the user; and
calculating the second biological information based on the second signal; and
performing a predetermined action of the application based on a status of the second biological information acquisition.
