eCommerce Onboarding with Silent Authentication

Potential Solution

eCommerce platforms need to verify users without disrupting the purchase process to protect conversion and revenue during checkout. They need to confirm phone number ownership and, at the same time, ensure buyers have a smooth, invisible onboarding experience. This can be accomplished by using Vonage Verify Silent Authentication as the primary verification method for low-risk users, reserving OTPs only for cases that require extra assurance.

Note: Fallback channels can be any Verify workflow option (for example, SMS, Voice, WhatsApp, RCS, or Email). SMS and Voice are shown in this use case only as examples. For details, see Verify workflows.

Silent Authentication directly verifies a phone number with the mobile carrier, eliminating the need for passwords or OTPs. This background process improves confidence that the phone number matches the onboarding device. Silent Authentication can be easily integrated into any business using the Vonage Verify API.
