I want to use Firebase Face detection in Android. As far as I read, it can detect faces. Can I save the detected face and compare it next time for authentication?

No, at the moment, ML Kit only does face detection, and gives you face landmark coordinates. It will be a very inaccurate method if used for face authentication.

Can I save the face detected as jpg/png or bitmp? – Sweety Bertilla Jul 14 '18 at 00:51

Definitely. The ML Kit will give you the coordinates of the face detected. So you can certainly crop out the detected part from the the bitmap. – Pannag Sanketi Jul 16 '18 at 15:56
