SMS codes have long been considered not the most secure authentication method, so Google is trying to stop using them. The outdated and insecure method of confirming identity during authorization will be replaced by more reliable QR codes.

Currently, one of the authentication options in the Gmail mail service involves sending a six-digit code via SMS. However, this method is associated with various security issues. For example, SMS codes can be forged or the user may not have access to the device to which verification SMS messages are sent.
In the coming months, Google will replace SMS codes with QR codes. Instead of entering a number and receiving a code via SMS, users will need to scan a QR code using their smartphone’s camera app to complete the authentication process. This approach is expected to help users protect themselves from phishing scams, where fraudsters trick potential victims into giving them verification codes via SMS.
Other authentication options, such as dedicated apps or security keys, will continue to be relevant even after SMS codes are phased out. Google also offers users a “Sign in with Google” feature that allows users to use other Google apps as an authentication method.
