The AT&T MFA app for Chrome is a companion to the AT&T MFA mobile app, providing a secure and convenient way to authenticate your login credentials. This Chrome extension allows you to use your phone as a security key authenticator for the Chrome browser.

AT&T MFA simplifies the authentication process by eliminating the need for passwords or 6-digit codes. With a simple push to login feature, you can securely access your accounts without the risk of falling victim to phishing attacks.

Utilizing the FIDO Universal 2nd Factor (U2F) and WebAuthn (FIDO2) protocols, AT&T MFA ensures secure and un-phishable authentication on the web. By downloading the AT&T MFA authenticator app on your smartphone, enabling the Chrome browser extension, and scanning the QR code, you can easily get started with this secure authentication method.

One of the key advantages of AT&T MFA is its zero trust architecture. Your keys and login information are never accessed by the developers, as they only reside in the app on your phone. This adds an extra layer of security to your authentication process.
