How to do phone verification in Go with Twilio Verify

This blog post demonstrates how to send an SMS one-time passcode (OTP) in Go using Twilio's Verify API, which can be used for user onboarding or authentication. To follow along, you need a Twilio account, verify service, and install Go with the Twilio helper library. The code sets up imports, instantiates the Twilio client, and defines two functions: `sendOtp` to send the OTP via SMS and `checkOtp` to check the user's input against the sent OTP. After running the code, you can test the verification lifecycle by replacing your phone number with a new one and seeing the output. The post also provides next steps for account security, including experimenting with different channels and exploring other authentication methods.
