PayPal has been working with fingerprints for allowing users to login for quite some time. They already supported the Fingerprint API that Samsung has been using for their smartphones. It has supported many other smartphones with fingerprint sensor like the Moto G4 Plus, Nexus 5X, Nexus 6P and the Honor 8. But now it appears to be getting official, and proper support of Nexus Imprint. Users likely have seen the fingerprint support available in PayPal already, but now it should be much more widely available.
To set up your fingerprint for login with PayPal all you need to do is go into Settings and under Login and Security, you'll see the option to set it up. If you haven't already used PayPal on your smartphone, you can simply download the app and when you login, the app will prompt you to register your fingerprint, if you wish to do so. Which is definitely something you should do. It'll make logging in a whole lot faster and seamless.
With PayPal's OneTouch, they are also allowing you to checkout in other apps using PayPal by authenticating with just your fingerprint. It's said that fingerprints are more secure than passwords, and they are definitely easier to authenticate with than typing in a long password, which the majority of people probably have laying around somewhere, where anyone can access it. PayPal says that the latest version of their app, which should be v6.5.1 is rolling out to the Google Play Store right now and should be available in the next few days for everyone. You can check the Google Play Store and see if the update is ready for you, right now.
PayPal relaunched their Android app earlier this year. Giving it a huge makeover, as well as adding in a slew of new features. And it looks like they aren't quite done yet. As the PayPal app has just gotten official Nexus Imprint support, and this will work with any smartphone with a fingerprint sensor running Android 6.0 Marshmallow or later. PayPal notes that they are always listening to customer feedback, so if you have issues with the app, be sure to let them know so they can fix whatever issues you may be experiencing.
