There is no one-size-fits-all answer to this question, as the use of Google face recognition technology will vary depending on the specific application or service you are using. However, in general, you will need to first provide a database of images that contain faces that you wish to be recognized. Google's face recognition algorithms will then analyze these images and attempt to match them with faces in new images that you provide. The accuracy of the recognition will vary depending on the quality of the images you provide, as well as the specific settings and algorithms you are using.
