Google has good news for iPhone users

iPhone users, you can now use your device to unlock your Google account. This is possible after the internet search giant has rolled out an update for Smart Lock on iOS.
As part of the update, iPhone users will be able to use the handset’s “built-in security key.” It uses Secure Enclave as a security key reveals one Googler while replying to a user’s query on Twitter.
This Secure Enclave is found on Apple’s A-Series chips that stores Touch ID and Face ID.
Once you download this updated version of the Google Smart Lock app on your iPhone, you will be required to select an account to “Set up your phone’s built-in security key.”
Now that the iPhones support this Google feature, every time a user will enter a Google account credentials, they will be prompted to open Smart Lock on their nearby iPhone in order to confirm a sign-in. If you want to cancel, you can click on “No, it’s not me” option.
