Google has open-sourced OpenSK, firmware that, combined with an affordable chip dongle, allows you to make your own security key to use for authentication purposes.

About OpenSK. OpenSK isan open-source implementation for security keys that supports both FIDO U2F and FIDO2 standards.

"Under the hood, OpenSK is written in Rust and runs on TockOS to provide better isolation and cleaner OS abstractions in support of security," Elie Bursztein, Google's Security & Anti-abuse Research Lead, and Jean-Michel Picod, Software Engineer, Google, explained.

"By opening up OpenSK as a research platform, our hope is that it will be used by researchers, security key manufacturers, and enthusiasts to help develop innovative features and accelerate security key adoption," they said.

More information and instructions on how to make a personal security key with OpenSK are available on the project's GitHub repository.
