The effective cross-channel two-factor authentication technology of the Vonage Verify API helps you to protect your users and business against fraud and spam. Build trust and increase conversion across channels by sending a short code (PIN) to your user's telephone, verifying user identity. No telecom or security experience is required with this all-in-one, economical user verification API.
How it works
Vonage's Verify API verifies the identity of your user. When a user logs into his account on your app, Verify sends a one-time verification code to the phone number associated with the username and password, via an SMS, voice message or push notification. The user enters the verification code into the input box presented by your app. This confirms that the person attempting to access the account has the phone linked to that account. Your app then gives full access to the user.You only pay for successful verifications.
