I am im the market for a hardware key for MFA. I want to put it on my keyring and put it in my pocket so I always have it with me. I guess it should be quite sturdy for that (no easily broken off connectors, …) I mainly want to use it as additional factor for my Bitwarden vault. Do you have any recommendations, experiences, stories? Yubikey seems to be by far the brand most recommended. Solo is nice bc open source hard/firmware, but I care more about reliability and usability than openness I think.

Thank you for your insights!
