An OTP (or One-Time Password) is a dynamically generated numeric or alphanumeric string of characters that is used to authenticate and verify users before a transaction or a session in an app/website. Used by businesses to boost data security and prevent phishing attacks, an OTP service provider ensures timely delivery of OTPs to the right customers via SMSes and voice calls.

Choosing a reliable OTP service provider is the key to implement a robust authentication system. Below are some of the important factors to consider:
1. Delivery and Latency Rates: Always choose a provider that can assure you of better OTP delivery rates and lower latency rates.
2. Flexible APIs: If you are implementing an OTP authentication system using APIs, then make sure that your OTP service provider’s APIs are flexible and easy to implement in your backend systems.
3. Data Security: Your customers’ data should be your number one priority. Always choose a provider that is ISO certified and exercises enterprise-grade security practices.
4. Scalability: Always choose a provider that can quickly scale-up or down according to your business needs.
5. Customer Service: Choose an OTP service provider that values your time and truly cares about your success. Always ask if you are getting timely support in case you run into problems.
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.

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.
