Summary

Later versions that used low-energy Bluetooth or near-field communication worked natively with Android devices but so far have been a nonstarter with iOS users, who complain the devices don't always work reliably.That has left Google scrambling for another FIDO-sanctioned way for the masses to do 2fa. Another shortcoming was that Android keys weren’t available to users logging in from an iOS device.On Wednesday, Google is addressing this last drawback with a new method that brings Android keys to iPhone and iPad users. It relies on the Google Smart Lock app running on the iOS device that communicates over Bluetooth with the built-in key stored on the user’s Android phone or tablet. The weakness doesn’t automatically mean Bluetooth is insecure, but it does suggest that the channel may be less suited for highly sensitive security protocols than some engineers recognize.Further ReadingIranian phishers bypass 2fa protections offered by Yahoo Mail and GmailSo for the time being, I have no plans to use Android keys when logging in to Google on my iOS devices.
