To be able to make use of the phone verification system, you are required to have a Nexmo account. Nexmo is a gateway provider who will deal with verifying your clients for you. Nexmo automatically chooses the best method to verify an account by either sending an SMS or by calling them.

• Go to https://dashboard.nexmo.com/register and proceed with the signing up process.
• Verify your email address, and then you have to verify your mobile number.
• Then, head to https://dashboard.nexmo.com/private/topup and top up your account with credit to be able to verify phone numbers.
• Then, head to https://dashboard.nexmo.com/private/dashboard and make note of your API Key and Secret values, as you will require them later when you configure the module.
