I no longer receive phone calls for two-step login at my cell phone.

I’d like to use a YubiKey/U2F key. Are there any in particular ITS recommends?
ITS recommends the Yubico Security Key. Some departments may wish to purchase them in packs directly from Yubico for a slight discount. They are also available from Amazon.
U2F keys work with the latest version of Chrome. Anyone with a brand new Apple MacBook Pro will need an USB-A adapter or YubiKey 4C. Linux users may need their systems set up for U2F depending on the type of key they use.
