iPhones Can Now Be Used to Generate 2FA Security Keys for Google Accounts

A new update to Google’s Smart Lock iOS app lets users set up their iPhone or iPad as a security key for two-factor authentication when signing into native Google services via Chrome browser.

Once the feature is set up in the app, attempting to log in to a Google service via Chrome on another device such as a laptop results in a push notification being sent to their iOS device.
