Case Study: SendGrid strengthens account security with Twilio 2FA

Sendgrid Replaces Homegrown 2fa Solution with Authy Cloud Service

SendGrid, a leading cloud-based email delivery platform, faced a challenge with its in-house two-factor authentication (2FA) system. As the company grew and its customers' needs evolved, the homegrown SMS-based solution became problematic for users without cellular service and could not scale to support new features like team member invitations. SendGrid turned to Twilio to replace its legacy 2FA with a robust cloud service.

The solution implemented was Twilio's two-factor authentication service. This provided SendGrid with a secure, expert-built system that included new features like push notifications. The implementation was straightforward, allowing SendGrid to get up and running quickly. The results included a scalable and flexible 2FA solution that aligned with SendGrid's cost model and freed its developers to focus on core email delivery products instead of maintaining security software.
