What about 2FA?

>>> Two–factor authentication (2FA) provides an additional layer of security to passwords by adding the requirement for a physical device to be present when logging in. This means even if someone obtains your password, they can’t log in without access to the device in question — this can be a physical security key, or a dedicated 2FA app such as Google Authenticator or Authy (authy.com) — installed on your phone. For more on how 2FA works and what to look out for, see “Authenticator apps…” on p72.
