Google to Replace SMS Authentication with QR Codes for Gmail Security

The shift aims to address security vulnerabilities in SMS-based two-factor authentication and reduce SMS-related abuse globally.

Google has confirmed plans to phase out SMS-based two-factor authentication for Gmail in favor of QR code verification within the coming months.
SMS authentication has been criticized for vulnerabilities like phishing, SIM-swapping, and traffic pumping scams, which compromise user security.
The new QR code system will require users to scan a code with their smartphone, removing the need for SMS codes and reducing reliance on carriers.
This change aligns with Google's broader efforts to enhance account security through alternatives like passkeys, authenticator apps, and physical security keys.
No specific rollout date has been announced yet, but Google has emphasized the need for stronger protections against malicious activity.
