Systems, methods, and non-transitory computer readable medium use external databases for biometric authentication. A server receives a request for authentication of a user from a requestor. A notification is sent to a user device associated with the user from the server. A biometric image is received within the server in response to the notification. A biometric ID of the user is sent from the server to an external database for identifying a biometric template stored with the external database. An authentication result indicative of a match between the biometric image and the biometric template is determined and the authentication result is sent to the requestor. The external databases are owned by a third party, and the biometric template of the user was previously generated and stored within the external database in association with the biometric ID.
