Project description:
"When a user signs in to my website, I want an SMS one-time password sent instantly to any phone, whether it’s running Android or iOS. The flow should be simple: the visitor enters a phone number, receives a numeric code by text, then submits it to complete the login.

I haven’t chosen a gateway yet, so feel free to recommend and configure whichever service—Twilio, Nexmo, or any other reliable provider—that best suits fast delivery, regional coverage, and clear reporting. Security matters: codes must be random, time-bound, single use, and validated server-side before the session starts.

Deliverables
• Clean, well-documented code (backend + minimal frontend hook) that triggers, sends, and verifies SMS OTPs
• Gateway setup with test credentials and clear instructions for going live
• Brief hand-off notes so I can adjust expiry time, message template, or sender ID later

If everything works smoothly—code arrives in seconds and blocks reuse—I’ll consider the job done and future phases open for discussion." (client-provided description)
