How spam and botnet prevention works
1. The user enters his/her phone number
As 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 makes a phone call and delivers the code via text-to-speech.
3. The user enters the authentication code
The user receives the message and enters the authentication code in the installer screen.
4. Vonage APIs Verify validates the code
Behind 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 spammers
If 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.
