About
Twilio Verify is a separate API just for one-time passcodes. Those 6-digit login codes. It handles the whole flow: sending the code by SMS, voice call, email, WhatsApp, or authenticator app, checking the code the user types in, blocking fraud, and retrying if the first attempt fails. Way simpler than building login-code logic yourself.
