Mobile biometric verification is in many ways superior to a traditional password because of its convenience as well as resistance to common attack vectors. But even with that, this method still faces its fair share of threats. If a hacker were to gain access to a user’s biometric data, that user cannot be able to reset their biometrics the way they might reset a compromised password. Malicious actors can also utilize fake mobile biometric input to spoof mobile devices.
Biometric authentication is simply the process of verifying the identity of a user based on unique physical characteristics, such as the user’s voice, retina, fingerprint or facial features, and it presents various advantages. The most common approaches to mobile biometric verification are fingerprint scanning and facial recognition. The biggest advantages to these two methods is the degree to which biometrics simplify authentication.
Mobile biometrics come out ahead of other biometrics due to the fact that the users’ data is stored on the device and never transmitted across networks or collected on centralized servers. In order to gain immediate access to the mobile device, mobile users only need to place their finger on a scanner or look at their device’s camera. They don’t need to enter or remember complex passwords and passcodes or deal with password refreshes.
Mobile biometric verification based on physical characteristics happens to be more secure compared to traditional passwords. This is due to the fact that each user’s biometric characteristics are unique, and so the biometric authentication factor ensures a high degree of certainty that the person logging onto the device is indeed the real owner of that device.
While password-based authentication can still work, it is notoriously flawed and hackable. Users can forget, lose, or accidentally divulge their passwords, and hackers can steal or crack passwords. With mobile biometric verification, it is much more difficult to guess the authentication factor or trick users into revealing it. Moreover, users cannot forget biometric factors in the way they could forget a passcode.
