I've found Solokey to be unreliable. Recently, for example, I learned that the Solokey 2 can't be added to iCloud as a security key

I have multiple Solo Key 2 devices. (I bought a Kickstarter 4-pack.) I use one of them regularly, and I successfully added it to iCloud as a security key. It has been 100% reliable.

In August 2022 they released a major firmware update. Maybe that addressed the iCloud incompatibility and reliability issues?
