"So the Somu is really nice. This just works straight out of the box.... this is really an open source solution that provides the capability for you to be able to hack around with these dongles."

MickMake

"Most popular security keys, like the Yubikey, are closed sourced which limit their usefulness for hackers like myself. So now with the introduction of Somu, an open sourced alternative, tinkers are free to run wild."

Hackster News

"The guys making the SoloKeys are doing a great job. For an open source project, they're doing excellently. They were easy to get into contact with (on Github) when I needed help updating my Solo Secure and are receptive to suggestions."
