The index.html file containing JavaScript that makes use of the
FingerprintAuthenticator API functionality is listed below.
The following examples show how you can use various methods of the FingerprintAuthenticator.
Creating a new instance of the FingerprintAuthenticator object:
1 | var authenticator = window.launchbox.Authentication.authenticator(window.launchbox.Authentication.Type.FINGERPRINT_AUTHENTICATOR); |
Checking if the device has been equipped with hardware that enables fingerprint authentication and if the user has already enrolled any fingerprints:
1 2 3 4 | authenticator.checkAvailability() .then(function(isAvailable){ console.log("Is Fingerprint Authentication available? " + isAvailable); }); |
Saving the credentials in the device's fingerprint-secured keychain:
1 2 3 4 5 6 7 | authenticatior.create({identifier: "user", password: "rules" .then(function(){ console.log("Created"); }) .catch(function(err){ console.log(JSON.stringify(err)); }); |
Retrieving the credentials from the device's fingerprint-secured keychain:
1 2 3 4 5 6 7 | authenticator.authenticate() .then(function(payload){ console.log("Authenticated with " + JSON.stringify(payload)); }) .catch(function(err){ console.log(JSON.stringify(err)); }); |
Deleting the credentials from the device's fingerprint-secured keychain:
1 2 3 4 5 6 7 | authenticator.remove() .then(function(){ console.log("Data removed"); }) .catch(function(err){ console.log(JSON.stringify(err)); }); |
