Most of us regularly use our credit or debit cards for online transactions and nearly everyone has some sort of social networking account in their name with private details kept in it. In this day and age, where all resources and services are accessible within a few clicks, it is obvious to purchase anything online or transact money.
Users are now becoming more responsive about making powerful and complicated passwords for making their personal data safe. That definitely is one step ahead, but it is not sufficient. The one security solution increasingly being implemented by financial institutions, banks, IT companies and topmost social networks is two-factor authentication or 2FA.
One Time Password Through Bulk SMS
Two-factor authentication depends on something that user understands, i.e., login ID and password and something they physically have like mobile, USBs, or some other devices. Once you implement two-factor authentication processes, you have to enter one time password or OTP into system, which you get on the device you have. As it's only you who have the access to the device no one will be able to break your security layer.
For example, if you make a transaction by using your Internet banking account or pay bills online, you must log in with a password you are acquainted with and then to complete the transaction you would require punching in the numbers present on your debit card grid, which you have and type in the OTP that is delivered to your mobile phone through bulk SMS. In other words, the security keeps up with you in a device you have. The hacker may find out a user's password, but it will not be easy for him to crack the one time password that the user gets on the device the possess.
As we know that 2FA can stop cyber attacks, we should definitely opt for it to make sensitive information and databases safe in advance. You can improve the online security by allowing Two factor Authentication with web applications, network, IT infrastructure and emailing system where you require entering a username as well as password.
