   <li><a href="https://onlykey.io/">OnlyKey</a> - Another open-source option, OnlyKey supports TOTP codes, YubiKey compatible OTP, and U2F, making it very compatible with most websites. It also has a hardware PIN lock in case the device is lost or stolen. We would like to see GPG smart card support and a variety of form factors (USB-C, NFC) before recommending it for general use.</li>
+  <li><a href="https://www.nitrokey.com/">Nitrokey</a> - A variety of security key products for different workloads. All Nitrokey products are open-source and customizable. The <a href="https://www.nitrokey.com/sites/default/files/NitrokeyFirmwareSecurityAuditReport05-2015.pdf">firmware</a> and <a href="https://www.nitrokey.com/sites/default/files/NitrokeyHardwareSecurityAuditReport08-2015.pdf">hardware</a> have been independently assessed by Cure53 in 2015. We have found that there is no best overall product (the <em>Pro 2</em> lacks Curve25519 while the lower-end <em>Start</em> supports it, for example) and they are lacking a variety of form factors such as USB-C and NFC that would be more convenient for many users.</li>
