The present disclosure is applicable to the technical field of fingerprint recognition, and provides a fingerprint authentication method and system and a terminal supporting a fingerprint authentication. The fingerprint authentication method includes the following steps: a fingerprint receiving step: receiving fingerprint information input by a user; and a fingerprint template matching step: selecting a fingerprint template that has a highest using frequency from fingerprint templates on which matching has not been performed, and matching the fingerprint template with the fingerprint information. A fingerprint authentication succeeds when the fingerprint template matches with the fingerprint information, and the fingerprint template matching step is re-performed when the fingerprint template fails to match with the fingerprint information. In the present disclosure, by learning and making statistics of operating habits of a user, adjusting a matching sequence of fingerprint templates, and matching by directly using a fingerprint template having a highest possibility of successful matching, the speed of fingerprint recognition can be effectively increased, and better user experience can be brought about for users.
