Twilio has added support for Google Authenticator and other Time based One Time Passcode (TOTP) compliant applications in its Authy API. This update allows users to opt-in for two-factor authentication using an authenticator app, reducing friction and increasing security. The new feature is easy to implement, requiring only a few lines of code, and can be enabled by switching it on in the Twilio console. Using the Authy app provides additional security benefits, including push authentication and secure self-service recovery options. Customers can also use the Authy SDK for total control over their application's authentication experience.
