Google is making it easier for people to lock down their accounts with strong multifactor authentication by adding the option to store secure cryptographic keys in the form of passkeys rather than on physical token devices.
Google’s Advanced Protection Program, introduced in 2017, requires the strongest form of multifactor authentication (MFA). Whereas many forms of MFA rely on one-time passcodes sent through SMS or emails or generated by authenticator apps, accounts enrolled in advanced protection require MFA based on cryptographic keys stored on a secure physical device. Unlike one-time passcodes, security keys stored on physical devices are immune to credential phishing and can’t be copied or sniffed.
APP, short for Advanced Protection Program, requires the key to be accompanied by a password whenever a user logs into an account on a new device. The protection prevents the types of account takeovers that allowed Kremlin-backed hackers to access the Gmail accounts of Democratic officials in 2016 and go on to leak stolen emails to interfere with the presidential election that year.
