Google Will Discontinue SMS Authentication in Gmail and Adopt QR Codes, Strengthening Security and Practicality in the Two-Step Verification Process.
According to information from Forbes, Google confirmed that Gmail will stop using SMS codes for authentication. The change aims to enhance user security and reduce abuse. According to the company, the new method will be based on QR codes, eliminating the reliance on text messages, which are deemed vulnerable.
Google Wants to Abandon the Use of SMS for Authentication
Ross Richendrfer, spokesperson for Gmail, stated that just as the company wants to stop using passwords with the use of passkeys, it also seeks to move away from sending SMS messages for authentication. The statement was made in an email conversation with the company. This is the first confirmation that SMS codes will be abandoned.
Currently, Google uses SMS codes for two purposes: security and abuse control. Authentication ensures that the user is the same with each access. Abuse control prevents criminals from creating thousands of accounts to send spam and malware.

The new approach, according to Richendrfer, aims to lessen the impact of the misuse and global dependency on SMS.
Reasons for the End of SMS Codes
SMS codes present security challenges. Richendrfer explained that these codes can easily be the target of phishing.
Additionally, users may not have access to the device where the code was sent. There’s also the reliance on the security practices of the carriers. “If a fraudster manages to trick a carrier and obtain someone’s phone number, the entire security value of SMS disappears,” he stated.
Another problem involves a scam known as “traffic pumping.” In this scheme, criminals make online service providers send large volumes of SMS messages to numbers they control.
For each message delivered, the fraudsters receive payment. Google has identified an increase in this type of fraud in recent years, making the replacement of SMS even more necessary.
QR Codes: The New Authentication Method
Google’s new solution will utilize QR codes. In the coming months, the company will reinvent how it verifies phone numbers. Instead of entering a number and receiving a six-digit code, a QR code will be displayed that the user will need to scan with their phone’s camera app, explained Ross Richendrfer.
QR codes offer significant advantages in terms of security. The main one is the reduced risk of phishing. Since there won’t be a numeric code to share, users cannot be tricked into providing that information to criminals. Another advantage is the elimination of reliance on the telephone carrier to protect against abuse.
The Impact on Gmail Users
Kimberly Samra, a colleague of Ross Richendrfer at Google, emphasized that the transition to QR codes represents an important advancement. According to her, SMS codes pose a high-risk source for users. The company is pleased to introduce an innovative approach that reduces the attack surface and keeps users more protected against malicious activities.
The company did not reveal an exact date for the implementation of the new feature. However, they assured that more information will be shared soon. For Gmail users, the expectation is that this update will bring more security without complicating the authentication process.
The Future of Authentication in Gmail
The abandonment of SMS codes follows a broader trend in the technology sector. The use of QR code-based authentication, combined with other solutions, such as passkeys, enhances protection against cyberattacks. The new approach promises not only to protect users but also to hinder fraudulent operations that exploit flaws in the text messaging system.
Google concluded the statement with a promising message: “Stay tuned for more news soon.” This transition marks an important moment for digital security, bringing a more robust and effective authentication method to millions of Gmail users worldwide.
