Searching for answers about the rumored Steam data breach involving 89 million user records? You’re not alone. Many Steam users are alarmed by reports that a hacker is selling millions of user records online, sparking fears about account security and personal data exposure. However, Valve, the company behind Steam, has officially responded to the situation, stating “this was not a breach of Steam systems.” Let’s break down what was actually leaked, what it means for your Steam account, and whether you need to take any action to stay safe.
Reports first surfaced from cybersecurity blog BleepingComputer, which claimed that a hacker was selling a massive dataset — allegedly containing 89 million Steam user records — for $5,000. The data includes historical SMS messages with one-time passcodes (OTPs) used for logging into Steam, alongside recipient phone numbers. Understandably, this led to widespread concern, especially among users who rely on SMS for two-factor authentication (2FA).
But Valve quickly stepped in to clarify that their internal systems were not compromised. According to a statement from Valve, the leak involved old text messages sent as part of their 2FA process. These codes were only valid for 15 minutes and were not linked to any user passwords, payment information, or full account data. Crucially, the company emphasized that no Steam accounts were directly exposed, and there is no evidence suggesting Steam’s databases were accessed or breached.
Some users speculated that the breach could be related to Twilio, a third-party communication platform known for handling SMS and verification codes. One X (formerly Twitter) user suggested that Twilio may have been the source of the leak. However, Twilio issued a firm denial, stating they had found “no evidence of a breach” after reviewing the leaked data.
Valve also responded to the speculation, confirming that it does not use Twilio to send its login codes. This double assurance further distances Steam from the leaked dataset and points to the possibility that the origin of the leak may lie elsewhere — potentially with a third-party vendor or outdated message routing system.
Given that the leaked data only consists of old SMS OTPs and phone numbers — and lacks critical data such as passwords or linked Steam accounts — Valve says users do not need to change their passwords or phone numbers. However, the company strongly recommends that users activate the Steam Mobile Authenticator, which is more secure than SMS-based 2FA.
With account security a growing concern in today’s digital landscape, especially in the gaming community, using the Steam Mobile Authenticator ensures that your login process is protected by time-based codes within a secure app, not vulnerable SMS systems.
This incident underscores the growing importance of secure authentication methods in the gaming industry. With cyberattacks becoming increasingly sophisticated and lucrative, even legacy data like old OTP messages can find its way into hackers’ marketplaces. Although no active Steam accounts were compromised, the situation serves as a wake-up call for gamers to review their digital hygiene.
Using multi-factor authentication (MFA) apps, enabling email alerts for unusual activity, and avoiding third-party software can help keep your account secure. Steam has invested heavily in protecting its users, but as this situation shows, leaks can occur indirectly — often through outdated systems or unrelated third-party services.
Valve’s transparency in addressing the alleged Steam data leak highlights its commitment to user privacy and trust. While the leaked data appears limited to outdated login OTPs and unrelated to current accounts, it’s a reminder that security is a shared responsibility. Steam users should take a few minutes to enable mobile authentication and review their privacy settings.
