‘OTP’ stands for ‘One-Time Password’, and as the name implies, OTPs are used to authenticate and verify users whenever they initiate a transaction or a session on your app/website. However, to send OTPs to your customers’ mobile numbers you will need an OTP service provider like Exotel. Exotel provides OTP services like SMS OTP Service, Voice OTP Service, and missed call verification services. To know how to use our OTP solutions for your business, schedule a callback from our experts.
To put it in simple terms, this is how it works:
1. Your customer clicks on the ‘Verify’ button on your app or website.
2. A unique OTP is generated in your backend system.
3. Exotel sends the same generated OTP to the customer’s registered mobile number (This can be done through SMS or voice call).
4. Your customer enters the unique OTP sent by Exotel on your app or website.
5. If the entered OTP matches with the generated OTP, the customer is marked as verified. Get our free ebook - ‘Exhaustive guide on 2-factor authentication’.
Passwords have been the primary form of customer authentication since the beginning of the internet. However, having a password-only authentication system will put businesses at an increased risk of data breaches, phishing attacks, and security threats. Therefore, most businesses use OTP services to implement two-factor authentication (2FA) into their login systems or transaction portals. With two-factor authentication enabled, your customers will need a one-time password or OTP (in addition to their registered password) to complete the transaction. To know more about 2FA, download our free ebook - ‘Exhaustive guide on 2-factor authentication’.
Any business that deals with sensitive customer information can make use of our OTP services. Some examples of the sectors that use OTP services are banking, healthcare, e-commerce, insurance, transport, etc. You can schedule a callback from our experts to understand how to implement an OTP-based authentication system for your business.
It’s fairly simple. All you need to do is sign-up on our website and a dedicated account manager will get in touch with you to help you set-up the OTP authentication system for your business.
