SMS OTP Verification API

SMS OTP Verification API

Send OTP to your clients to verify their accounts or for whatever use you want. Implement MFA or send promo codes with this API.

API description

About the API:

This API will allow you to send OTP (One-time Passwords) to your users. It's ideal to improve security and have Multiple Factor Authentication on your sites/apps.  

 

What this API receives and what your API provides (input/output)?

You will pass the receiver's phone number and the API will automatically send a code to the user. You later will have the opportunity to verify the sent code and authenticate the login or whatever you need to authenticate. 

 

What are the most common uses cases of this API?

Prevent online identity theft

One of the great advantages of using one-time passwords to secure access is that they become invalid within a few seconds, which prevents hackers from retrieving the secret codes and reusing them.

Reduce support from IT team

When choosing an MFA solution that is natively 2-factor, and therefore where along with the OTP there is no need to require the user to enter the combination login & password (passwordless MFA solution) - then and again only then - IT support teams are less likely to be solicited from end-users for password resets. For sure, end-users are unlikely to make a mistake with a simple knowledge factor such as a PIN code to be remembered. It’s a win-win for users and support teams.

Overcome password security issues

Once again, this is the case only when going for a passwordless authentication that is natively 2-factor. IT administrators and CISOs can avoid the common issues encountered when it comes to password security (weak passwords, sharing credentials, reusing the same password across multiple accounts and systems, etc.).

Improves user experience

While some MFA solutions will send OTP by push notification or SMS to users, asking them to retype and enter it in their login window. MFA generates and validates OTPs in a way that improves the user's login experience. Indeed, the solution will silently generate and validate the OTP, in a transparent way for the user, allowing him/her to have a simple and passwordless login experience.

 

Are there any limitations with your plans?

Besides the number of API calls per month, there are no other limitations.

Prices are based on a recurring monthly subscription depending on the plan selected — plus overage fees applied when a developer exceeds a plan’s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.
