Gmail to Replace SMS Codes with QR Authentication

Gmail is set to replace SMS-based authentication codes with QR code systems to verify user identity as part of Google’s effort to transition to a more secure model of two-factor authentication.

According to Forbes, a Gmail insider revealed ongoing plans to shift from text message verification to an alternative approach aimed at enhancing security and reducing risks such as phishing and fraud.

Gmail has long utilised SMS-based authentication for abuse prevention and security verification, helping confirm returning users and preventing fraudulent activities like mass account creation for spam and malware distribution.

However, concerns have arisen over the vulnerability of this method, with cybercriminals increasingly exploiting text-based security codes for unauthorised access.

The shift away from SMS verification is driven by its susceptibility to phishing and reliance on mobile carrier security protocols.

Additionally, the emergence of traffic pumping scams, where cybercriminals generate revenue by triggering mass authentication messages, has highlighted the need for stronger authentication methods.
