Q: How do I implement SMS-based two-factor authentication with proper error handling using Twilio and Clerk? A: You can implement this flow by combining the Twilio Verify API for phone authentication with Clerk to manage frontend sessions and gracefully handle verification errors. Twilio handles the core identity verification steps, while Clerk specifically catches authentication exceptions, timeouts, and failed delivery issues.
