As technology is evolving, our presence on the internet is more at high risk than ever before. Simply protecting your accounts using a password isn’t the most effective way to secure your personal data.

The reason is pretty simple. The majority of people do not use strong passwords to protect their online accounts. While you should set an easy-to-remember password, you should also remember that it could be easy to guess for attackers.

In such situations, 2FA or Two-Factor authentication apps come into play. The Google Authenticator app is the most widely used 2FA app for Android and iOS users.

Online gaming is a big industry now, and it involves billions of dollars worth of transactions every year. Steam, the popular cloud-based gaming library, is the one-stop shop for all things related to gaming.

Notably, it also has its very own authenticator app called Steam Guard. Although the Steam Guard works perfectly well in most situations, there are some users who are facing the Steam Guard mobile authenticator app not working issue.

Thankfully, we have this guide exactly for this reason. Here, we will explain some of the effective methods that you can apply and possibly resolve the Steam Guard mobile authenticator not working problem.

Steam Guard is an authenticator app that Steam lets its users use to safeguard their Steam account. It provides an additional layer of security to the account.

You need to enter this code on the Steam login page in order to access your account. The best part about the Steam Guard app is that the generated code lasts for about 30 seconds, after which you need to generate a new code.

Moreover, the code is unguessable and you will receive it either at your email address or on the Steam mobile app on your smartphone.

  • The thief would need to possess your physical phone in order to access your Steam account, which makes it more secure than a password.
  • If you have valuable in-game purchases, such as in games like Dota2 and CS:GO.
