One-time password - option or a "must have" for your business security?

May 30, 2017

One-time password (OTP) is a password that is valid only for one login session or financial transaction. As the OTP term expires after one session, it automatically becomes immune to repeated attacks on the network (network attack in which the actual transmission is maliciously or fraudulently repeated).

OTP generation algorithms typically use pseudo-random or random scenarios. Some of them are based on time, while others use mathematical algorithms.

The time-based OTP (TOTP) algorithm generates a password based on the current timestamp, the shared secret key (or perhaps something more unique to each account). IT-Decision Telecom experts specify that, when the user enters OTP, which he received (or generated locally using TOTP), the server again generates OTP, since the time stamp (usually 30 seconds) will be the same, it will be the same password, and the server checks the password. In this way, the server asks you to enter OTP within 30 seconds or 60 seconds.

 

How to configure an OTP?

 

Authentication of users on the website is the most important factor for any business. And nowadays with the development of OTP technologies, SMS is considered to be one of the most secure authentication processes. By sending a one-time password (OTP) to mobile numbers, businesses can check users when they want to make the necessary transactions.

 

Now let's look at how OTP works

 

The OTP authentication process works by a simple method, because when a website wants to check a user, they usually ask the user to enter their mobile phone number for verification. When the user enters his/her number and presses the "Send" button, a random code is generated and delivered through the service of bulk sms mailings to the mobile phone of users in real time. When a user receives a randomly generated code, he enters this code on the website and identifies himself.
