New in V2: - More secure microcontroller supporting secure boot, PUF, flash encryption, etc. - Firmware rewritten in rust. - Much more robust and durable construction. - Touch buttons, reversible USB-A, USB-C NFC is passively operated similar to other authenticators and is more reliable. ED255 is supported in V2!

Did I guess right what "reversible" means? Maybe the page should actually say, so readers are not obliged to guess. My first thought was that it had USB-C on one end and USB-A on the other. But studying the pics did not confirm that. Does it support installing more than one key?

  Reversible refers to the plug. USB-C is of course reversible, and USB-A also is. There’s no constrain on the number of keys. You can use 1 device with unlimited sites, both v1 and v2, because keys are generated on-the-fly and not stored. (There’s a limit on number of resident keys, and we supported 50 in v1, while for example yubikeys support 25. So far these are rarely used, if ever.)

    I have a Somu. The docs I have found say it can only store one resident key. Is it particularly limited, vs. the Solo v1?
    - ecesena 6y ago
      No, it's incorrect. Do you have a link so we can fix? Somu can store 50 resident keys exactly like Solo v1, as it has exactly the same MCU. In both there's a single master secret that's used to derive the (non-resident) keys. That's the only thing that's unique.

If ED works with ssh, I'm very interested and I'll buy a few as long as price isn't outrageous - I don't mind supporting development. I have a couple of somu, but ed25519 didn't seem to pan out (haven't tried). Personally, I would prefer flush mount and/or tactile buttons, but NBD. Hope they will be available on other than kickstarter, as I never got it to work, with all their tracking and what-not.
