EffectivePhone verification prevents bulk account creation and eradicates spam more effectively than captchas or social logins.
Better user experienceMinimizes personal information sharing (compared to using social network registrations) and enables a nearly frictionless registration experience for mobile users.
GlobalEvery user with a phone has a unique identifier, enabling you to grow the audience for your application with confidence.
How spam and botnet prevention works
1. The user enters his/her phone numberAs part of the registration process, the app asks the user to enter his/her number.
2. Vonage APIs Verify sends a code
Verify sends a text message containing an authentication code to that number. If the user is on a landline, Vonage APIs automatically make a phone call and delivers the code via text-to-speech.
3. The user enters the authentication codeThe user receives the message and enters the authentication code in the installer screen.
4. Vonage APIs Verify validates the codeBehind the scenes, Verify confirms that the user has entered the correct code. If so, the app installation can continue.
5. And weeds out the botnets and spammersIf the code is incorrect, Verify can prompt the user to re-try. If the correct code is never entered, your app can cancel the installation process.
Programmable elements used in this solution
Why choose Vonage APIs for spam and botnet prevention?
Local compliance solvedVonage APIs compliance engine, with built-in knowledge of global numbering plans and local regulations, ensures that messages are delivered and don’t get caught by carrier filters. For example, the sender ID and message templates adapt automatically to ensure delivery in every country and carrier so you don’t need to write different code for each destination.
Verify only valid numbersVerify validates that a user’s number is current and valid — even before trying to send a message to that number — eliminating outbound messages to bogus numbers or numbers that are not in service.
Manage the contingencies automaticallyVerify detects if an authentication code has not been entered and automatically sends a second code if necessary. In addition, it automatically detects landline numbers and uses Vonage APIs text-to-speech engine to deliver validation messages as voice calls instead of SMS.
Predictable charges, billed only on conversionVerify aligns Vonage APIs goals with your goals by charging a flat fee for verifications — and charging only for successful verifications. Capitalizing on Vonage APIs experience in delivering more than 3.5 billion phone verifications worldwide, Verify has been optimized to exceed benchmark conversion rates.
