The devise-twilio-verify gem extends the Devise authentication system to provide enhanced security through two-factor authentication (2FA). It integrates with the Twilio Verify API to send verification codes via SMS or TOTP (time-based one-time passwords). This gem simplifies adding 2FA to Devise-powered Rails applications, ensuring better protection for user accounts. For instructions on migrating from the legacy Authy API (devise-authy) to Twilio Verify, please refer to the README.
