After Google has updated support for hardware security keys on iOS, owners of iOS devices running iOS 13.3 or later can configure more types of security keys for their Google accounts for two-factor authentication (2FA/2SV ).
However, using hardware security keys to access Google accounts or apps on iOS is not easy.
On June 3 this year, Google added the Titan security key for iOS 13.3 or higher iOS devices.
In 2019, Google collaborated with the identity authentication device company Yubico to produce a USB-C Titan security key.
And the ability to protect high-value Google accounts on iOS devices with security keys will improve the security of many companies.
