KOMPaaS.tech adds a new user authentication method to its telecoms platform

Telecoms operator and software solutions developer KOMPaaS.tech announces the launch of Call Verify, a new user authentication service.

The service enables businesses to verify the phone numbers of website and app users through an outbound call, without the need for SMS messages or one-time passcodes, helping to reduce user verification costs.

Call Verify is designed for banks, online marketplaces, taxi and car-sharing services, delivery companies, CRM system developers and other digital platforms and application providers.

What sets Call Verify apart from existing call- and SMS-based authentication methods is its verification process: users confirm their phone numbers by making a voice call, without receiving an SMS or manually entering any codes.

Call Verify streamlines the authentication process for digital services and applications whilst maintaining a high level of data privacy. The service offers a more reliable and cost-effective alternative to popular Confirmation Call and Password Call solutions.

How Call Verify works

Users enter their phone number on a website or in an application. The KOMPaaS.tech platform then generates a unique phone number for the verification call, taking into account the specified session time window, and passes it to the client’s service. The number is displayed to the user, who then calls it.

Once the call is received, the platform checks the Caller ID and sends the verification result to the client’s service. If verification is successful, the user is granted access to the service via the website, personal account, mobile application or other interface.

Unlike traditional SMS verification and other phone call-based number verification methods, Call Verify does not require users to receive and manually enter a verification code. This simplifies authentication and reduces the number of steps required to access a digital service.

Reducing authentication costs

One of the key advantages of Call Verify is its ability to significantly reduce phone number verification costs.

The service starts at just £0.0005 per API request. For comparison, the minimum cost of SMS authentication is £0.07 per API request, whilst Password Call starts at £0.01 and Confirmation Call at £0.01 per API request.

Call Verify can therefore provide a cost-effective alternative to existing phone number verification methods, particularly for services handling high volumes of user registrations and logins.

Easy to use and accessible

Call Verify simplifies the user experience: instead of waiting for an SMS or voice message, users simply make a call to the displayed number. There are no codes to remember or enter, reducing the number of steps required to register or log in to an application.

A mobile internet connection is not required to make the call, as it is placed over a mobile or fixed-line telephone network.

Call Verify can be used as a standalone phone number verification method or as an additional authentication option alongside other solutions.

More information about Call Verify and other two-factor authentication (2FA) solutions is available on the KOMPaaS.tech website.
