In today’s world of increasing digital crime and internet fraud, security of online systems and their access is critically important, however, traditional modes like passwords and captchas are not enough. Hackers are using an alarming variety of attacks like phishing, brute force, web app attacks, the point of sale intrusions etc., to steal passwords and wreak serious havoc. According to reports, around 75% of breaches leverage stolen or weak passwords – this is not surprising since standard security procedures usually require a simple username and password making it increasingly easy for criminals to breach systems and gain unauthorized access to data and critical systems. Users tend to make it easy for criminal hackers, by indulging in practices like weak passwords, using the same password across multiple applications or keeping the same password for long periods. These practices may help them remember their logins, but they invite hackers in through the front door.
