Android Native Fingerprint and Chrome Browser

This section walks you through the steps required to experience passwordless authentication with the Nok Nok banking demo application on an Android phone.


  1. Go to using a Chrome browser.
  2. Enter a unique Username (your email address works well) and click Next.
  3. For Password, enter "noknok" and click Sign In.
  4. Click the drop down menu in the upper left of your screen and select Settings.
    Settings shows your information for Passwordless Sign In and Second Factor Sign In.
  5. Select Passwordless Sign In.
  6. Let's create a FIDO registration with the native fingerprint on the Android device by selecting Setup.
  7. Click on “Get Started” and Choose “Use Security Key with Fingerprint”
  8. Swipe your fingerprint when prompted to complete the registration.
  9. You can see that the registration is successful by checking the list of Registrations on the Settings screen. A Generic FIDO2 Authenticator should be listed.
  10. Now let's sign out and try passwordless authentication.
    Click the drop down menu in the upper left of your screen and click Sign Out.
  11. At the sign in screen, ensure your username is present and click Next.
  12. Swipe your fingerprint when prompted and you are signed in to your account.
  13. At this point you have demonstrated creating a FIDO2 registration and using it to authenticate without a password.
  14. Try more functions in the demo. For example:
    • The Account Recovery feature.
    • On the Pay a Friend screen, notice that sending a large payment to your contact Pat Johnson may require more authentication. First try sending $100, then send $1000. Notice that transactions greater than $501 have a different policy that requires an additional authentication.
    • Click Open New Account on the sign in screen. This will walk you through creating an account and setting up authentications and recovery methods without ever using a password.
    • On the Settings screen, create a second factor authentication by selecting Second Factor Sign In from the drop down menu and clicking Setup or Setup with QR Code. Second factor works by first requiring a username and password and then a second authentication that you've set up. Note that it's easiest to try this by first removing any existing registrations before creating a second factor authentication.
