Google Enhances Two-Factor Authentication: What You Need to Know

Google has recently made significant improvements to its two-factor authentication (2FA) setup process for both personal and Workspace accounts, emphasizing the growing importance of enhanced security measures in digital platforms. Also known as 2-Step Verification (2SV), this feature plays a crucial role in safeguarding user accounts from takeover attacks, particularly if passwords are compromised.

Streamlining 2FA Setup

The updated process simplifies adding a second verification step by allowing users to directly set up methods like authenticator apps or hardware security keys without first needing to use SMS-based authentication, which is considered less secure. This update is especially beneficial for users of Google Authenticator or similar time-based one-time password (TOTP) apps, who previously had to enable 2SV using a phone number before adding an Authenticator.

Options for Hardware Security Key Users

For those using hardware security keys, Google now offers two methods to integrate them into their accounts. Users can either register a FIDO1 credential or assign a FIDO2 passkey to their account, providing flexible and secure options for account authentication.

Policy Updates and User Autonomy

Google's update also includes a change in how 2FA settings are managed. If an administrator turns off 2SV, the second steps of verification will no longer be automatically removed from the user’s account unless specifically done so from the Admin console or via the Admin SDK. This ensures that off-boarding workflows for users remain consistent and secure.

The Rise of Passkeys and Modern Authentication Challenges

Over the past year, more than 400 million Google accounts have adopted passkeys for passwordless authentication, which are part of modern authentication methods designed to counteract phishing and session hijacking. These methods use cryptographic keys generated by devices like smartphones and computers to authenticate users, rather than relying on passwords that are vulnerable to theft.

However, new challenges have emerged. Research from Silverfort revealed that threat actors could potentially circumvent FIDO2 security by executing an adversary-in-the-middle (AitM) attack, which can hijack user sessions in applications using single sign-on (SSO) solutions like Microsoft Entra ID, PingFederate, and Yubico. These attacks expose the flaws in how session tokens are handled post-authentication, allowing unauthorized access if these tokens are intercepted.

Securing Sessions with Advanced Techniques

To combat these vulnerabilities, adopting techniques like token binding is advised. This method cryptographically binds security tokens to the Transport Layer Security (TLS) protocol layer, ensuring that authenticated sessions are strictly used by the client. While token binding is primarily supported by Microsoft Edge, Google has introduced a feature in Chrome called Device Bound Session Credentials (DBSC) to protect users against session cookie theft and hijacking attacks.
