YubiKey 5C NFC review
A YubiKey 5C NFC is a small physical key for signing in to accounts that support it. The useful combination for a creator working between a computer and a phone is USB-C and a contactless NFC tap. I’d check the login settings on the accounts that matter before buying one.
Check where the key will work
This model supports FIDO2 and WebAuthn. It plugs into a USB-C port or taps against a compatible NFC device. Check the individual service and browser, especially if you usually sign in from your phone. WordPress.com, for example, documents USB security keys as an option after two-step authentication is enabled. If you run a self-hosted site, check the login system you actually use.
EFF’s Surveillance Self-Defense helps you look at account security and privacy more broadly. The YubiKey has a narrower job. For a supported FIDO2/WebAuthn sign-in, it gives the service its own credential.
Plan for the day you lose it
A spare key only helps once the service knows about it. WordPress.com’s guide shows how to register another key as a backup. Check your other accounts individually for a second key or recovery option before you start relying on the one on your keyring. I’d keep a registered spare somewhere separate, especially if the first key travels with the laptop.
Anabel’s take
I’d check the email account that receives password resets first, then the dashboard I use to publish. If I could register a backup for both and use the key from the devices I actually carry, this model would make sense for my setup.
