Hi Guys, Your Nitrokey products are still very price competitive compared to Yubikeys, and have the added advantage of being firmware upgradable. I have been bitten by the firmware vulnerabilities of Yubikeys which are non-fixable, so future purchases will be of Nitrokeys once I figure out if they support PIV login to Macs, and what Common Criteria certification means compared to FIPS certification. I think you have a winning combination, please keep up the good work!
