Multi Multi-Factor Authentication

Multi-Factor Authentication (MFA) has been around for decades, but the devices used in this process have evolved significantly. With smartphones, laptops, tablets, and even wearable computers becoming commonplace, it's essential to ensure that MFA systems can accommodate multiple devices without compromising security. Authy, a two-factor authentication platform, has tackled this issue by allowing users to add more devices while minimizing vulnerability. The platform uses an intelligent multi-key system and offers features like 'inherited trust,' which allows a trusted device to authorize another device, and de-authorization, which enables quick removal of devices. These measures help protect against persistence attacks and enhance the overall security of MFA systems.
