Thetis FIDO2 Security Key (folding USB-A)

4.4/10verdict: skip

This is a folding USB-A security key for people whose computers have USB-A ports and who want a low-cost second factor. It suits buyers who check the exact model listing first, because the research is unclear on whether this version supports FIDO2 or only U2F. It is a poor fit for anyone who needs USB-C, NFC or documented certification beyond FIDO2 L1.

TrustKey T110 FIDO2 Security Key

5.1/10verdict: good, not the best

The TrustKey T110 is a USB-A FIDO2 key for people who want passkey or second-factor login on computers with USB-A ports. It suits those who want the listed resident key capacity and simple setup, and who can accept a lower certification level and no USB-C or NFC support. Buyers who need phone support, higher certification or published durability ratings should look at other keys.
