My Solokeys from the Kickstarter arrived

Unlike the few other Kickstarter projects I participated in, this one delivered on time.

This is a FIDO2 U2F key for 2 Factor authentication.

I got the 3 pack of regular USB A keys. There is also a USB C version and a NFC version.

They each came with a random color silicone boot and also a single pack of additional boots in red, green, blue, black and white.

Blue boot with the bare Solokey. That's a little RGB LED in the middle of the switch. It lights up through the silicone, it's visible, even through the black boot.

Back side of the Solokey. They also have a hacker version that you can customize the firmware on. This is a regular model, and has a bootloader that allows updating the firmware with signed images over USB. More info on their github page.

With the silicone boot installed. It's a tight fit. I would not plan to switch boot colors once you have one of these installed.

Bare PCB next to the original U2F Zero. The Solokey PCB is 2mm thick. It fits very snugly in a USB port. The U2F Zero had a 1.5mm PCB and wobbles a bit.

I'll probably get a few NFC ones once they are available. You can pre-order them here.
