Yubikeys are still not biometric unless you're buying the super-super expensive one. They are just very secure MFA. (in that it's extremely hard to read the secrets from them even with physical access)
Don't they just spit out the long password when you press them, I'd figure it would be easy to just plug it into your phone and copy the output if you had physical access
It's OTP. Once a code has been seen, all the previous ones no longer work. There's no point in copying.
There's a second slot that can be used for static passwords. But don't, obviously.
That is but one method of Yubikey. They also support cryptographic passkeys and can store TOTP secrets as well as PGP crypto keys.
The "touch key random key" is a OTP code that can be used for legacy software, Passkey and/or other functions are more valuable to me. Can read more about OTP security here.
