Here the FIDO2 is playing a major role and the fundamental part of the FIDO2 design let never share your fingerprint to Google servers instead of that it only shares the correctly scanned cryptographic proof.

Fingerprints Authentication Working Mechanism

When the users accessing Google services such as Passwords.google.com, First it issues the WebAuthn, a core component of the FIDO2 Project that helps to authenticate the users to web-based applications.

FIDO2 Project is a joint effort between the FIDO Alliance and the World Wide Web Consortium (W3C) whose goal is to create a strong authentication solution for the web.

According to Google. ” Now, when the user visits a compatible service, such as passwords.google.com, we issue a WebAuthn “Get” call, passing in the credentialId that we got when creating the credential. The result is a valid FIDO2 signature. “
