Build a Phone Authentication App
summary
Builds a working phone-auth app that uses Svelte front end, Appwrite backend, and Twilio SMS OTP to send and verify one‑time codes; demo successfully receives an OTP on a Twilio trial‑registered number. Setup requires Docker (or one‑click hosts), filling .env keys (APP_PHONE_PROVIDER, accountSid, authToken, APP_PHONE_FROM, Appwrite project ID and endpoint), restarting containers (docker compose up --force-recreate), and running npm run dev. Code and repo are publishable for hackathons and class projects.
