Yubico recommends a spare key
Why is a spare key so important?
It’s best practice to keep at least one spare YubiKey in case your primary is lost or stolen. Having a spare key gives you the assurance that you will not be without access to critical accounts when you need them most. No need to fear being locked out of any accounts, and no need to go through a lengthy recovery and identity verification process to recover them.
Please note that to register your spare key you will need to follow the same process as registering your primary key. Not all services support registering multiple YubiKeys. More information: yubico.com/spare.

The Security Key Series is a hardware based authentication solution that provides superior defense against phishing, eliminates account takeovers, and enables compliance requirements for strong authentication
The Security Key Series offers superior security by combining hardware-based authentication and public key cryptography to effectively defend against phishing attacks and eliminate account takeovers. It offers support for FIDO U2F and FIDO 2.
The Security Key Series helps organizations accelerate to a passwordless future by providing support for the FIDO2 protocol. FIDO2 supports not only today’s two-factor authentication but also paves the way for eliminating weak password authentication, with strong single factor hardware-based authentication.
Easy, Fast and Reliable
The Security Key Series provides a simple and intuitive authentication experience that users find easy to use, ensuring rapid adoption and organizational security. With authentication speeds up to 4X faster than OTP or SMS based authentication, security keys do not require a battery or network connectivity, making authentication always accessible.
