Yubikeys support OTPs, you can configure and read them using the Yubico Authenticator application on desktop/mobile.

  To expand on that (for those who might not know), the actual secrets are physically on the Yubikey and the Authenticator app on iOS or Android is using them to generate the One-Time Password. This means you can also roam those secrets to different devices (as they are on the Yubikey). But it also means that you need to have access to the key whenever you need the OTP! One caveat is that you can "only" have 32 or 64 accounts per Yubikey (number depending on the version of the key)

    That number has to be so big I’d be absolutely confident to never exceed it before ever considering it. Nobody has time to manage/backup multiple keys with the fun game of ‘what account is stored on which key’.
