Fingerprint API Support Added to United Airlines App

Last year, when Google announced Android 6.0 Marshmallow along with the Nexus 5X and Nexus 6P, they also announced a new API which is known as the Fingerprint API. This API allows apps to use the fingerprint sensor on your device. Now while it uses the fingerprint sensor, it doesn't actually take your fingerprint. That is all done through the OS. So you don't have to reregister your finger for each and every app. The way it's done, it's actually really easy to use. And that's definitely important, especially when Google is wanting more and more people to use their fingerprint for security.

There are already a slew of apps on the Play Store that support the Fingerprint API, and now the United Airlines app can be added to that list. The update that was rolled out to the United Airlines app today brings a slew of bug fixes, but the most important part of that changelog is indeed the Fingerprint API support. You'll be able to now login to your MileagePlus account  in the app without having to type in your password, again. You will need to type it in when you first login to the app (read: when you first download the app), but after that, you'll be able to link it to your fingerprint. Now when you need to login to your MileagePlus account in the United Airlines app, just touch your fingerprint sensor, and you'll be all good to go.

That's now all that you can use your fingerprint for, though. Within the app, there are more options for using your fingerprint as authentication. One of those is when you are booking a trip with either your miles or cash, you can authenticate it using your fingerprint. As well as entertainment, which you can purchase through the app while you're 30,000 miles in the sky. It's a much easier way to authenticate purchases, then having to relogin to your account and typing that long password each and every time.

The update to the United Airlines app is available on the Google Play Store today. It's likely a staged roll out, so if you aren't seeing it just yet, give it a bit and you should see the update soon.
