In today’s world of the internet and technology, almost everything is automated or computerized. On automating services like banks and security devices, it is imperative that proper security measures be taken so that these technologies and software are not easily beaten or hacked into. This requires setting up of passwords to authenticate a user in order to prevent unauthorized access to sensitive information about a person.

Although passwords help these systems verify and authenticate users, there is always the threat of passwords being compromised, which could lead to all sorts of trouble for the victimized person. If your bank account’s PIN was to be leaked somehow, the consequences could be catastrophic for you. This calls for the need to have more secure passwords and better technology to protect people from being harmed in this way.

The use of biometrics has shown people the way forward as it uses personal physical details like fingerprints or iris scans to grant access to users for anything from their cell phones to their bank accounts. In this article, we see what the future could hold for the world of passwords and biometrics. Below are some advancements that have been made and could be built on further to help people secure themselves better against password threat.

Multi-step authentication

Multi-step authentication uses multiple layers of protection for any service that you want to use. The most basic example that one can think of is accessing you email account. Many email providers like Gmail have the provision of setting up a two-step authentication process to access your account.

The first step is the traditional entering of username and password, which is followed by a unique code being sent to your registered phone via an SMS. Although this strengthens one against password theft, it can be cumbersome to wait for an SMS every time you want to access your emails, especially when you are traveling. It might even be possible that your phone is damaged and, therefore, you have no way of getting a unique number on it.

Voice Recognition

The latest sector to use this is the banking system. In India, ICICI Bank has recently launched this service to check if a call has been made by an authorized user. The user needs to call from his registered mobile number, and as he talks with an executive, a software runs his voice sample against a bank of voice samples of authorized users for a match. Although this helps in better results and shorter calls, the success rate is 98%, meaning sometimes unauthorized users are granted access while authorized ones are denied.

Combination of Iris Scanner and Pattern Password

It was Android with its 4.1 software version that first brought iris scanning to users for their smartphones. It required scanning the iris of your eye from the camera. This is a great way to protect your phone from being handled by unwanted users as the iris is unique for every person and cannot be altered unless externally damaged.

There is a downside in that the software is not perfect in scanning the iris. So if it is not sure that you are the one accessing it, it will prompt you for a pattern or numerical password to be entered, as set by you, to ensure that authorized access is taking place.


Passwords offer the advantage of being changeable, but they are highly exposed to the risk of being stolen or compromised. The future of authentication, therefore, lies very much with biometrics, with techniques like fingerprint scanners, voice recognition software and iris scanners doing the job well.

Although these technologies, too, are not 100% secure as there have been cases when such software have been beaten, it depends on the sophistication of the software integration if it can be perfect. Traditional passwords, on the other hand, are way more susceptible to theft and breach
