Review on Yubico YubiKey 5C Nano - USB-C Two Factor Authentication Security Key - Enhanced Online Account Protection Beyond Passwords - FIDO Certified USB Password Key - Ultra Compact Size by Richard Surveh

Useful, but I got tired of plugging and unplugging the authentication key. I personally find it easier to use a phone authenticator app. If I could leave the device connected to the network and it would work stably that would be great, but I've never been able to get it to work stably with a number of websites. In my experience, Google's login authentication process is fuzzy, I have to wiggle the key for it to work. I like the idea, but the actual execution doesn't match my personal experience.
