Authenticating customers or users over mobile phone or on your website is one of the most significant factor for any business. Nowadays, many businesses rely on OTP SMS for secured online transactions. They send SMS, OTP to users when they wants to make any significant transactions on their site or over mobile phone.
When a website wants to authenticate the user, they simply develop a token or random code and send OTP SMS over user’s mobile phone. Once user receives the token or randomly produced code, then they would submit those details and verify themself.
Let’s suppose, one of your user has forgotten password and wants to reset it, then user verifies account credentials and after that, you as an enterprise owner will send the one time password through Transactional SMS API. User will get a password over phone and enter that to authenticate further on your website. Therefore, you are securing user’s account and transactions.
If you have in-house software developers, then they can add this feature on your website or IVR system. Or you can appoint software companies to do the same.
There are many OTP service providers available, but MSG91 provides fast delivering SMS Gateway API to send OTP over user's mobile phone. So, the user will not wait have to for longer time to get their authentication code to verify themself.
Overall, authenticating users through SMS has become a very safe platform for any business and if you are not using this feature, then try and implement it now.
