Today we are pleased to announce the OnlyKey DUO launch on Kickstarter! With the same features users love about OnlyKey, OnlyKey DUO is one of the most versatile security keys available and in a small form factor that now supports both USB-A and USB-C.

Fast and Easy to Use

No need to install any software. You can use your OnlyKey DUO immediately for two-factor authentication and passwordless login (FIDO2) supported by major websites such as Microsoft, Google, Facebook, Dropbox, GitHub, Okta, AWS and more. Google and other vendors have recently come out with security keys that support either USB-A or USB-C so users end up buying two security keys or are forced to use an adapter. OnlyKey DUO is like two keys in one. It natively supports both USB types and it is one of the smallest and most portable security keys out there.
