American Express updated its Amex Mobile app today with one notable new feature: the ability to login into your account using Touch ID.

Log-in securely with the same user ID and Password you use on americanexpress.com. And now, enjoy quicker access with Touch ID, available for supported devices with iOS 8.

The new features utilizes Apple’s Touch ID finger print sensor, which in iOS 8 was opened to third-party apps for logins after previously being reserved for unlocking the device itself and authenticating App Store and iTunes purchases. For that reason the new feature is only supported on devices with TouchID running iOS 8. Devices with Touch ID include iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air 2 Plus, and iPad mini 3. 

The updated Amex Mobile app, version 4.6.4, is available on the App Store now and also includes other “bug fixes and enhancements.”
