Google will need to replace Gmail's six-digit SMS authentication code with QR code in the coming months. As confirmed by Gmail spokesman Ross Richendrfer, the change aims to reduce global SMS abuse and improve security. Although two -factor authentication based on SMS (2FA) has been a widely used safety measure, it is delivered with vulnerabilities such as phishing attacks, SIM exchange and fraud.

A major problem with SMS -based authentication is that criminals can encourage users to share their verification codes or even access it thanks to safety weaknesses related to operators. Furthermore, the growing scam known as traffic pumps allow scammers to take advantage of the numerous SMS sent to the numbers they manage. By eliminating SMS code, Google aims to protect users from these risks while improving the reliability of the authentication process. With the new system, instead of getting an inspection code via SMS, users will use their smartphone camera to analyze the QR codes displayed on the screen. 

This method not only eliminates the possibility of stolen or intercepted code, but also eliminates the reliance on secure ways of mobile support. By implementing QR-based authentication, Google is strengthening Gmail’s security while providing a more seamless and secure login experience for users.
