What causes the authentication issue on Minecraft?

After going through the user guides that were used to fix this error, we concluded that the following are the reasons behind its occurrence.

  • A recent change in user name: Most of the gamers reported that while playing the game they changed their respective usernames for an instance and the Minecraft failed to authenticate your connection issue arised on their systems. For example, if one’s previous username was Thomas and he changed it to Red Thomas his game would be stuck and the error would be displayed on the screen. Hence, if you’ve recently changed your username log out from the game and re-login using your credentials to get rid of this issue.
  • Background Processes: If you’ve just come across this error it is better to close all the background processes because they might be creating a conflict. For example, if Steam is running in the background and even if Minecraft itself is running in the background, it might be responsible for Minecraft failed to authenticate your connection problem. Hence, navigate to the task manager and end all the background processes to get rid of this glitch. 
  • Outdated JAVA version: Java is very important software that is required by Minecraft to work properly. This software should also be updated to the latest version side by side with the game to accommodate for new features and bug fixes. If your Java version is outdated, it can trigger the Minecraft failed to authenticate your connection error.
