How do I use a U2F token when adding a Google account to my Macbook Pro I'm enrolled in Google's Advanced Protection Program, which means I can only authenticate with a physical FIDO U2F token on every sign-in.

Trouble is, that when I try using my Google account, I see "You can only use your Security Keys with Google Chrome".



Is there a way around this, or a way for me to use my U2F security key here?
There isn't a way to use your U2F token in this scenario.  U2F depends on browser support, and as of August 2018, only Chrome, Firefox and Opera support it.

As a workaround, you could set up Google Authenticator and use that to log in.
