Authenticating users over the phone or on your website is the most important factor for any business.

Most secured authentication nowadays many businesses rely on SMS. They send SMS, One Time Password (OTP) to users when users want to make any important transactions on their site or over telephone.

When websites want to authenticate an user, they simply create a token or random code and send One Time Password (OTP) to the user’s mobile phone.

Once user receives the token or random generated code, then user would enter those details and authenticate himself/herself.

When to use One Time Password (OTP)?

If you have a website, you can use it for several transactions like
Forgot Password.
Reset Password.
New User Registration.
Change Password.
Download important document.
Adding Funds.
Withdrawal Funds.
and for many more transactions.

Banks also use this to authenticate users for making important transactions on their site or telebanking.

How does it work?

Let’s say, one of your user has forgotten password and would like to reset them then user validates account credentials and then you as a enterprise owner will send an OTP via SMS. User gets a password on phone and enters that to validate further on your website. Thus, you are securing user’s account and user’s transactions.
