I thought this was an old feature when I encountered this yesterday.

Google is rolling out fingerprint login for Google services for both Android and Chrome for Android browser users.

According to the article, Google said fingerprint data are not sent to Google servers, it stays in the phone. Which was basically my worry.

Could this become the next "in thing" in apps and web logins? Would you take advantage of it?
