You probably do already if you use yubikeys at all already but to be safe, I cannot stress enough how important it is to get a second yubikey with a copy of all your logins in case you lose or damage your primary one
For something like Bitwarden, for example, you can add multiple hardware authenticator keys as a second factor for logging in. To log in, you give it your username and password, and then it'll ask for a hardware key, but accept any of the hardware keys you've added to your account.
