When you use your U2F security key, you see the following message:

"Let's update Your Security Key This update will allow you to use your security key in more browsers.  A pop-up window will prompt you to tap your key to update. Continue Skip this update."

If you enrolled a U2F security key before the update on June 4, 2019, you will be prompted to update your security key the next time you log in with Chrome using that U2F key.
