These are nice security keys, much like Yubikey, just without the Yubi part, which many open source enthusiasts will find refreshing. Will connect to all your devices too, due to having normal USB-A as well as USB-C and NFC.
I am not affiliated with the company Token2, but am reselling with their permission. This came about because buying a single piece direct incurs massive shipping and tariff charges; even more than the cost of the actual product. I decided to try buying in bulk and reselling here in the US in order to provide Americans with an economically feasible way of getting their hands on just one or two quickly.
