A one-time password (OTP) is an automatically generated numeric or alphanumeric string of characters. It is used to authenticate and verify users before a transaction or a session in an app/website. Used by businesses to ensure a secure user flow, an OTP SMS service provider ensures timely delivery of these messages.
Add an extra layer of security to your website and apps, without increasing the complexity for users. Authenticate registrations with OTP verification.

Exotel's API documentation and implementation process is extremely simple and easy to follow. There were no hassles in setting it up. We use other cloud telephony platforms as well but Exotel gets a big thumbs-up from us for their ease of use.
We have worked across cloud telephony players and with other vendors, but the fact is Exotel is dependable.
The number masking feature has been a very worthy addition to making our customer experience even better.
We used to use a traditional PBX system before. But that doesn’t have the capabilities of Exotel’s IVR system. So, we decided to use Exotel for our IVR cancellation system.
Exotel's automated calls have helped in increasing our service levels and reducing our costs since there is no need for any manual intervention.
Exotel's APIs are very clearly defined. Our tech team could integrate them in no time. It’s easy to incorporate into any product.
