An anonymous reader shares a report: In April, Google announced a groundbreaking technology that could allow Android users to use their smartphones as hardware security keys whenever logging into Google accounts on their laptops or work PCs. Initially, the technology was made available for Chrome OS, macOS, and Windows 10 devices. Today, Google announced it is expanding this technology to iOS as well. Today’s news means that iPhone and iPad users can now use their (secondary) Android smartphones as a security key whenever logging into their Google accounts on an iOS device. The technology works basically the same, as Google explained in April, at the Cloud Next 2019 conference.
