    Build what’s next.

    August 5th, 2026 at 9am PT Yubico Hackathon Hosted by Devs for Devs. Register by July 12 at 11:59pm PT.

    Use an exclusive YubiKey 5.8, write some experimental code, and push the boundaries of hardware trust.

    Move From Secure Login to Secure Action.

    Look, passkeys successfully solved the standard authentication headache. But if you are building modern software, you are probably already asking what happens after the user logs in. How do you cryptographically protect critical actions from session hijacking or AI-driven threats?

    The YubiKey 5.8 firmware changes the game by expanding passkeys beyond simple authentication and directly into privacy-preserving digital actions. No sales pitches, no marketing decks—just raw access to preview firmware and libraries so you can build, break, and test your own implementations before anyone else.

    Hosted by Devs for Devs.

    Claim your limited edition YubiKey 5.8 created only for the participants of the hackathon. Participation is limited. Register by July 12 at 11:59pm PT.

    Accepted participants will receive a custom lasermarked YubiKey and the top two winners get a gift card to Pluralsight.
