Why we recommend it
The YubiKey 5 NFC is the key we recommend first: USB-A fits most laptops, NFC covers phones, and FIDO2 makes phishing practically impossible. Buy a pair and register both — that’s the whole setup.
In our testing the highlights were clear: phishing-resistant FIDO2 login for hundreds of services; USB-A plus NFC covers older laptops and every phone; also does TOTP, PIV smart card and OpenPGP; no battery, waterproof, essentially indestructible.
It is not perfect — USB-A — get the 5C variant for USB-C-only machines; you still need a second key as backup. For most buyers in this category those trade-offs are easy to live with, but weigh them against your setup before you click buy.
