Passport allows you to use out-of-band authentication to authenticate to selected websites on a laptop or desktop computer. You can use the fingerprint sensor on FIDO UAF-enabled devices (such as the Samsung Galaxy S® 6, Fujitsu Arrows NX, or Sharp Aquos Zeta) or enter a simple PIN on non-FIDO enabled devices. You can enroll your Android device by using Passport to scan a QR code displayed by the website, then touch the fingerprint sensor or enter a PIN. Once enrolled, you can authenticate using a similar method. Alternatively, the website can send a push notification to your Android device and trigger the authentication.
This solution lets you use your Android device to better protect your online account, without requiring passwords or additional hardware tokens.
