Twilio Authy

Twilio Authy is a widely used two-factor authentication (2FA) application designed to provide an extra layer of security for online accounts. Originally founded as an independent startup named Authy, the service gained popularity for its cross-device synchronization and cloud backup features, which allowed users to recover their 2FA tokens even if they lost their primary mobile device.

In 2015, the brand was acquired by Twilio, a major cloud communications platform based in San Francisco, California. Since the acquisition, the product has been integrated into Twilio's wider suite of security and identity verification tools. While the desktop version of the application was recently deprecated in favor of mobile platforms, Authy remains a cornerstone of the Twilio security ecosystem.

Today, the product is developed and maintained primarily in the United States by Twilio's engineering teams. As the ultimate owner, Twilio oversees the software's infrastructure, global distribution, and security protocols, ensuring it remains a reliable choice for millions of users worldwide who require time-based one-time passwords (TOTP).
