Fingerprint Scan

With the fingerprint scan, you can use your unique fingerprints to authenticate. With Fingerprint Scan enabled, instead of authorizing authentication requests by sliding the authorization switch up, you'll use the fingerprint scanner built in to your mobile device to authenticate your finger.

Eligible Devices

Since accurately scanning your fingerprint requires specialized hardware on your phone or tablet, fingerprint scanning is only available on eligible mobile devices that both come with fingerprint scanners and extend the use of that scanner to mobile apps.


As of August 2014, the only eligible devices are the Samsung Galaxy S5 (Android) and Apple iOS8 devices with TouchID.

Setup Fingerprint Scan

Before you can begin using the fingerprint scan, ensure you have the fingerprint scanning function of your device enabled and configured with your fingers. Next, enable the fingerprint auth factor in your LaunchKey Mobile Authenticator settings menu by tapping the Disable/Enable on the Fingerprint Scan settings page.

Once enabled, LaunchKey Mobile Authenticator will use your devices fingerprint scanner to authenticate your fingerprint on all future authentication requests until Fingerprint Scan is disabled.
