NEW: Termii Voice OTP A Reliable way to verify/authenticate customers’ transactions

If you manage a website or an application (e-commerce, or banking, and financial applications/websites) you would know how powerful it is to have a great user verification service integrated into your processes.

The ability for a website or application to quickly and efficiently verify users’ identities and transactions is not only a recipe for improved customer growth/retention but also eliminates the risk of data security and phishing attacks. Cybersafety is crucial, and (one-time) passwords play a big role in that.

For organizations to effectuate digital identity technology that satisfies customers’ needs in the most secure and user-friendly way, it is critical to reaching customers through their personal technology — mobile phones. The mobile is now the desired method for customers to perform daily and stringent tasks like banking and shopping and must be placed firmly at the heart of any successful digital overhaul strategy. Businesses already adopting a mobile multi-factor authentication strategy — SMS, WhatsApp, and now Voice, for their customers will gain the most benefits.

However, securing information is a huge burden for many organizations and it has become a top priority to find a service provider that can provide the best security. Let’s take an example, the onboarding process where 2FA is needed to verify/authenticate a new user, faster time-to-value attracts customers. But if onboarding is slow and difficult, this can leave customers unhappy and dissatisfied, encouraging them to give up.

To solve these challenges, we’re excited to announce VOICE OTP, a powerful new alternative channel for organizations to verify their users’ identities and transactions.

Voice OTP Verification happens through a phone call to the user’s phone number. The user answers the phone to listen to the digits OTP (security number) played over the phone call, then enters the OTP in the application/web interface to verify a transaction or a login.
