Once there, Chrome will prompt you to authenticate your identity using your phone's fingerprint sensor. Adding to the pain is the fact that now we have got so many passwords to remember.
If you aren't familiar with FIDO2, the very short version is that it's a two-factor authentication method that means you won't need to use a password to log into supported services. Using the FIDO2 standard, created to improve authentication on the web (as opposed to on an Android app) users will only have to register their fingerprint or screen lock on their phone once to use it for a native app or the compatible Google services sites on the internet. And you can test out how well this new system works by running a little test on your Android device.
Your fingerprint (PIN number, pattern or password) is really just tied to a unique private key also stored on your device, which performs the account unlocking process. It's still secure, there's an implied lineage of authentication history (associated devices are "Bootstrapped" as Google calls it), it's just a whole lot more convenient than typing your password.
The new feature is arriving on Google Pixel devices today and access will arrive on all Android phones running Nougat or later over the next few days. As explained by The Verge, by using this method of security, credentials are stored locally, as opposed to being stored in a remote cloud server.
Goodbye passwords: Android is now FIDO2 certified FIDO2 certification is paving the way for passwordless mobile security. FIDO2 is much more secure than regular passwords.
Using these standards allows the company to provide password-less sign-in options on smartphone apps and web services.
