Please let me start by saying that Yubico is NOT the closed/evil. Without Yubico, we wouldn't have security keys, and we probably wouldn't have these standards.

Please let me start by saying that Yubico is NOT the closed/evil. Without Yubico, we wouldn't have security keys, and we probably wouldn't have these standards. They're working since 10+ years on this problem, and they released a great amount of open source. Some short term advantages of Solo: open firmware that can be verified by the community. Somehow a reference implementation maybe. Prices will be slightly lower, yes, but not a massive advantage imo. I also hope we can build an open documentation system, to make it easier for people to start using fido2 devices. Long term dreams. 1) Open hardware will allow for experimentation. I'm personally hacking security keys into jewels, and I hope that people will take Solo design, alter it, and embed security keys into other objects and shapes. Keys are getting obsolete. 2) Pushing the industry. Again Yubico is not the "closed one" here. Security coprocessors/chips are. Hopefully, by having more and more open hardware, there'll be a market for even more open chips.
