Google is transitioning from SMS-based two-factor authentication (2FA) to QR code verification for Gmail accounts. This change aims to mitigate the risks associated with SMS abuse, such as SIM swapping and message spoofing, which can lead to identity theft. By scanning a QR code with their phone, users will receive a more secure method of authentication. Google emphasizes that while dedicated authenticator apps and security keys are preferable, QR codes offer a simpler yet robust alternative to traditional SMS messages.
Instead of entering your number and getting a six-digit code via SMS, you'll see a QR code that you scan with your phone's camera.
A scammer can spoof such a message to trick you into providing the correct verification code.
Google is making this switch to 'reduce the impact of rampant, global SMS abuse.'
Gmail spokesperson Ross Richendrfer described this upcoming change as a way to address the vulnerabilities of SMS authentication.
