In this age of internet, shopping habits have transformed because of e-commerce companies. While buying online products, there are many things people don’t know about and one such fact is why banks and Etailers use a 6 digit One Time Password (OTP) code. If you remember old days, a 4-digit OTP was used as it was easier to remember. But, with the passage of time, companies realised the need for tight security as hacking got advanced. Before going further, lets first read what is the idea behind OTP and how it works.
What is an OTP?
OTPs are randomly generated combination of codes that are valid for a single login session of any user. OTPs generally require a secondary authentication in order to work which in the case of transactions is your card number and other security details. OTPs help payment gateways and banks to confirm your identity. Now, lets have a look why 6 digits are preferred for OTP:
Why 6 digits?
Along with being more secure than 4 digit codes, 6 digits are difficult to remember and they are nearly impossible to guess. They work on algorithms that help generate one time combinations that are unique to the user as well as that particular login session making it pretty hard to predict/guess them. A 6 digit code gives more space to generate unique combinations.
Moreover, it is difficult to see and predict a 6 digit code if someone tries to have a look from a distance. Do you have some other thoughts that can help companies to make e-commerce more secure? Do share them with us in the comments section.
