I’m yubikey curious. I’m just scared of losing it and locking myself out

Buy two and keep one in a safe place. When you go to create an OATH entry in your 2fa app (Yubico Authenticator, for example), have both on hand to load them up with the same account registration
Smart.
Many services that use YubiKeys provide users with a backup code, typically in the form of a hexadecimal string, that can be used to regain access to their accounts in case the physical YubiKey is lost or destroyed.
This backup code works similarly to a Bitcoin seed phrase.
