B2B SaaS Admin Onboarding with Silent Authentication

Potential Solution

B2B SaaS platforms need to verify phone numbers during first-time admin onboarding without delaying account activation. The goal is to confirm phone number ownership while ensuring a smooth onboarding process. By implementing Vonage Verify Silent Authentication as the default verification method for low-risk admin onboarding, SaaS providers can verify phone ownership in the background and reserve OTPs for exceptional cases.

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 provides direct verification of a phone number through the mobile carrier, removing the need for passwords or OTPs. This background process improves confidence that the phone number is aligned with the device used during onboarding. Silent Authentication can be easily integrated into any business using the Vonage Verify API.
