What is OTP SMS and how is it useful?
OTP stands for One Time Password. It is a password for a computer or digital device that can only be used once. OTP is a 4 or 6 digit security code that is sent to your registered mobile number as an SMS.
How OTP is generated?
Algorithms are used to generate OTP. It uses two inputs, the first being the Seed and the second being the Static Value, which never changes. It generates when a new account is created. In addition, the Moving Factor changes, so we get a new OTP every time.
In this, OTP is valid for a short period based on time-synchronization between the Authenticator server and the Client.
A new password is generated based on a Mathematical Algorithm.
Why OTP is used?
OTP password is more secure than normal password. Normal Password is created by the user himself to secure his account.
Normal Password can be cracked by any hacker in a short time, so all online service companies use OTP password which keeps your account completely secure.
This OTP is sent to you by the service providing company either through OTP Message or through Voice Call or through your mail, which makes it clear to the company that the user is an Authorized User. This keeps the user's account completely secure.
