A biometrics data recognition apparatus includes a computer device and a biometrics data recognition device, which includes a biometrics data sensor, a control processor and a storage. The biometrics data sensor captures to-be-recognized biometrics data of an organism. The storage stores template biometrics data and website login data corresponding to each other. The control processor receives and judges whether the to-be-recognized biometrics data matches with the template biometrics data and outputs the website login data to the computer device if a match occurs. The computer device communicates with a cloud server and extracts login format data from the cloud server according to the website login data, and combines the website login data with the login format data to make the computer device log in a website corresponding to the website login data. A biometrics data recognition method and a non-transitory tangible computer readable medium are also disclosed.
