How do I implement SMS authentication in my app?

To implement SMS authentication, you'll need to integrate an SMS gateway API like Twilio or Nexmo. Do you have a preferred service?

I think I'll use Twilio. What are the steps to set it up?

First, sign up for a Twilio account and get your API keys. Then, install the Twilio SDK in your app. Would you like help with the code?

Yes, please! Can you provide a code example for sending an SMS?

Sure! Here's a simple example in Python:

from twilio.rest import Client

client = Client('your_account_sid', 'your_auth_token')

message = client.messages.create(
    body='Your verification code is 123456',
    from_='+1234567890',
    to='+0987654321'
)

Replace the placeholders with your actual credentials.
