1. Who We Are

The company behind Solo 2 and the open source security key movement.

SoloKeys is a hardware security company focused on digital sovereignty. We design, manufacture, and sell open source FIDO2 / WebAuthn security keys — hardware and firmware you can fully audit, build, and trust.

2. Open Source Commitment

Openness isn't a marketing line — it's the foundation of everything we build.

SoloKeys products are built on fully open source hardware designs and firmware. Our source code, schematics, and build instructions are publicly available on GitHub so that anyone can audit, verify, and contribute.

Open Source Licenses

Hardware and firmware are published under open source licenses documented at github.com/solokeys:

• Firmware (Solo 2): Apache License 2.0 and MIT License
• Hardware schematics: CERN Open Hardware Licence v2
• Software libraries and tools: Apache License 2.0 or MIT, as specified per repository

Solo 2 Hacker Edition

The Solo 2 Hacker is a developer-focused device for custom firmware development. It does not include attestation certificates. By purchasing a Solo 2 Hacker, you acknowledge that you are using the device for development purposes, and that SoloKeys provides no warranty against user-applied firmware modifications.

4. Purchases & Pricing

What you need to know before you buy.

All prices are displayed in US Dollars (USD) unless otherwise stated. Prices in effect at the time of your order confirmation are final for that transaction.

Taxes & Duties

Sales tax is applied where required by applicable law. For international orders, customs duties and import taxes may be assessed by your local customs authority. These charges are the buyer's responsibility and are not collected by SoloKeys at checkout.

Order Acceptance

Placing an order does not constitute a binding contract until SoloKeys sends an order confirmation email. We reserve the right to cancel or refuse any order for reasons including pricing errors, product unavailability, or suspected fraudulent activity. If an order is cancelled after payment, a full refund will be issued promptly.

Returns & Refunds

Our Returns & Refunds Policy is incorporated into these Terms by reference, including our 6-month hardware warranty.
