Failed to Verify Username Minecraft – How to Fix

Failed to Verify Username Minecraft Error – Introduction

When it comes to playing Minecraft, many grand adventures await. From deadly kit PvP battles with your friends to just relaxing and building a Star Wars Death Star in creative mode. No matter what you and your friends enjoy, there are thousands of different Minecraft servers to enjoy and so it’s important that everyone can join and play without issues. If an issue does occur, such as the failed to verify username Minecraft error, it can be very frustrating to experience and so it’s important to get it quickly fixed.

The failed to verify username Minecraft error is one of the most common types of errors and it can occur for numerous reasons. This includes the Minecraft client not being authenticated, too many Minecraft instances being opened at once, or could be simply due to an older Minecraft version not supporting Mojang authentication. Minecraft’s authentication would be the login connection between your game launcher and Mojang’s login servers.
 
Let’s not wait any longer. Below, we’ll show you how to get this error fixed so that you can get back to enjoying Minecraft with friends on a Minecraft game server!

Reasons Failed to Verify Username Occurs in Minecraft

As mentioned above, a failed to verify username Minecraft error can occur for quite a few different reasons. In each section below, we will cover the problems that trigger this error and how you can get them fixed so that you can play Minecraft again!

Failed to Verify Username Minecraft – Using a Cracked Minecraft Client

A cracked Minecraft client can be one of the reasons why you’re facing a failed to verify username error. Cracked Minecraft clients are pirated or illegally obtained and hacked versions of Minecraft that allow users to play without having to login or purchase an account. By default, Minecraft servers are set to authenticate and check for authentic Minecraft players.
 
This means that if you’re using a cracked Minecraft client, and a Minecraft server checks the account, it will give you a “failed to verify username” message and kick you. Thankfully, if you own the server and can edit its settings you are able to disable the Mojang authentication to get around it. However, this will disable all types of account protections and if you do this, we highly advise using a plugin to add authentication such as AuthMe.
 
To disable Mojang’s authentication on your Minecraft server, you can follow these steps:

1. Head to your Minecraft server webinterface and stop your server.
2. Next, to the left under “Settings”, click on “General” to edit your server options.
3. Within your server options under “Server”, you will see “Online mode”. Uncheck this option to disable online mode for your dedicated Minecraft server.
   
4. Finally, after unchecking that option, press “Save changes”, and then start your server.
5. You can now reconnect to your Minecraft server to join and play!

Mojang Minecraft Servers are Offline Causing Failed to Verify Username Minecraft

While not often, Mojang Minecraft authentication servers, and their servers in general, can go down. If you’re unable to find the cause of the failed to verify username Minecraft error, we recommend checking if Mojang’s servers are online by reviewing their Twitter page. The Mojang team is great about reporting issues that occur and when they’re fixed, such as this recent issue:

Too Many Minecraft Instances opened at Once

Like many programs out there, Minecraft does not run properly if multiple instances of its program are open at the same time. When multiple of the same account are open at the same time, only the newest instance will be authenticated. To quickly resolve this, we recommend closing all of the Minecraft launchers and games you may have running. Then, re-open and launch Minecraft to enjoy another adventure with your friends in a server!

Older Minecraft Versions not supporting Authentication

Another cause of the verify username error can result from using an older version of Minecraft. For Minecraft version 1.6.4 and below, Mojang authentication servers are not supported. This results in servers running those versions to give players the failed to verify username Minecraft error. To get around this, you can disable Mojang authentication by disabling online mode if you are the owner of the Minecraft server.

You can disable online mode on your Minecraft server by doing the following:

1. Go on your Minecraft server panel and stop your server.
2. Then, on the left under “Settings”, select “General”.
3. Within your server settings, find “Online mode”. Uncheck this box next to this option to disable online mode on your Minecraft server.


4. After, press “Save changes” and start your server.
5. Finally, you can now reconnect to your server to play multiplayer with your friends!

Minecraft Launcher is No Longer Authenticated

After weeks/months of long adventures in Minecraft, sometimes the Minecraft launcher will no longer be authenticated. This means that since it has been a long time since you last logged into Minecraft, that login is no longer working correctly. To resolve this, on your Minecraft launcher log out and then log back in. Afterward, you’ll be able to join Minecraft servers again and continue your quests, battles, and builds!

Join, Explore, Survive, and Create on Your Minecraft Server

After following those steps, you will now be connected back to the world of Minecraft multiplayer. Having taken care of the dreaded failed to verify username Minecraft error, you’re now ready for any exploration whether it be against an Ender Dragon or a dangerous modded shark! See where your adventures take you when you bring your friends along on a Minecraft game server!
