Fingerprint and Retina Scanners vs. Passwords: Which is Best?

It’s easy to want to jump on the bandwagon for the newest tech especially when it comes to safety features. Why wouldn’t you want to implement the newest and best tech for your employees and clients? However, with new technology comes new risks including those items that offer more safety.

Internet of Things

The Internet of Things, or IOT, is any type of device that connects to the internet, and it includes many objects you might not expect. TVs, refrigerators, pacemakers, and even cameras – the list goes on. If the device ever needs to connect to the internet through a cable or wirelessly, even just for an update, it has the opportunity to be hacked. That can be very scary. This type of hacking isn’t something that is happening all the time, but it is a potential risk to consider.


The password for your TV can be reset, but what do you do if someone hacks or steals something that is biologically yours – say a fingerprint, RFID chip, or your retina? Biometrics is a term for a body part, measurement or calculation that can be used by computer science for identification and other purposes. Examples of these include the fingerprint scanner on your laptop or facial-detection software that unlocks your phone. Unlike your password, if these credentials are stolen or replicated, how can you get back that security?

Advantages and Disadvantages

Right now, biometrics are difficult to forge, but they are also very expensive to create, making them not very practical. If something is scanning a physical feature, that data is being uploaded somewhere and could be hacked. One of the best ways to protect against this sort of theft would be to have a system that requires multiple features to be scanned. This would include an eye scan, fingerprint, and possibly a voice-recognition test. Biometrics could be the future of password standards; however, technology grows faster than security can keep up with vulnerabilities.

Would you be interested in using biometrics for everyday item such as starting your car or unlocking your house? Until then, stick to using passwords. Longer passwords are better, and remember not to use the same password for multiple accounts.
