Introducing Vonage Silent Authentication

Vonage has introduced Silent Authentication as part of its Verify API, a recent development in personal authentication workflows that uses mobile phone SIMs to verify identities. This method removes the need for One-Time Passwords (OTPs) sent via SMS, reducing annoyance and increasing user flow resistance. Security benefits include reduced phishing threats by moving authentication directly between carrier and mobile device. However, limitations exist, such as requiring a mobile device with cellular data enabled, which can be a blocker in some cases. The Silent Authentication workflow involves starting the process with a call to start the verification, followed by a series of redirects to complete the request, and finally sending the code to be checked. Successful completion results in a seamless user experience, marking the start of a series of products from Vonage this year.
