Cloudflare has introduced phone authentication for Enterprise customers to enhance their support experience over the phone without compromising account security. Customers can now verify their identity during a call by providing a token generated from the Cloudflare dashboard or via a 2FA app like Google Authenticator. This feature is available to eligible Enterprise customers and can be configured through the Cloudflare dashboard or an authenticator app. The system generates single-use tokens using RFC 6238 compliant time-based one-time passwords, ensuring secure authentication during phone calls. Future improvements include giving users the ability to request a callback from a support agent within the Cloudflare dashboard.
