How to choose, what it's for and where to start.
FIDO2, U2F or a multiprotocol key?
U2F lets you use a key as a second authentication factor. FIDO2 can also support passwordless sign-in and passkeys, depending on the service and your account settings. Features vary between models. Security Key by Yubico focuses on FIDO2 and U2F, while the YubiKey 5 Series additionally supports protocols such as OTP, PIV and OpenPGP. Browse the YubiKey collection to compare models from this brand.
Match the connection to your devices
USB-A fits computers with a traditional USB port, while USB-C suits devices with that connector. NFC enables contactless use of a compatible key with a supported phone. The connector alone does not guarantee compatibility: check the requirements of your service, operating system and browser. Choose a Nano model when you want a small key that can stay in the port.
Plan a backup for account access
Before buying, check whether your service lets you register more than one security key. A separate backup key and securely stored recovery codes help you regain access if your main device is lost. Find other equipment for protecting devices and cards in Privacy & Protection.
