Android Marshmallow gave us a new API to authenticate users with the Fingerprint API. We can use the sensor, authenticate the user even within our application, and save it for later use if we want to save the need for user login using the Credentials' Grace Period capabilities Android Marshmallow introduced.

We also covered a way to make our application more secure using HTTPS only, and the StrictMode policy, enforced with the help of the usesCleartextTraffic flag, which allows us to make sure that all the nodes we connect to the outer world and examine the need for are a secure connection or not.

I would like to thank you for reading.

I would like to thank the Android team. This product has changed my life.

The Android ecosystem has great developers contributing by publishing libraries, writing blog posts and answering support questions; I'm proud to be part of it.

Looking forward for future editions.
