Is there a hardware MFA key that works both on laptop and iPhone? [closed]

I have a company issued laptop (running chrome OS). I need to use my company gmail on my iPhone. My corporate gmail account only allows hardware key as a 2-factor. I cannot use google auth as a second factor, the option isn’t there.

I would have to setup the a hardware key on the only machine I have the account working on, and then use it on the iPhone.

Is there a hardware key that will allow me to use it on both my work chromebook and my iPhone?
