Login Error: Failed to verify username/Connect to Minecraft

Before connecting to a Minecraft server, Mojang automatically checks if your account is real before allowing you to join to protect the server. When this fails, it displays Failed to verify username as the error message. 

The failed to verify username error usually occurs when Mojang's authentication servers cannot verify your account's login session. There are different solutions depending on the cause.

Having Multiple Sessions

Validation errors most commonly occur when Mojang detects multiple instances of the same login credentials. This is caused by logging in to your account while already logged in on a different device, or using multiple Minecraft launchers. Logging in and out of your account revalidates the session.

  1. Close your Minecraft client if it's running.
  2. Log Out of your account from the Minecraft launcher.
  3. Re-enter your account's email address and password to log back in.
  4. Launch Minecraft and connect to a server to verify if your account is validated.

Using a Non-Verified Account

By default, Minecraft servers only allow players with premium accounts to join. This can be bypassed by disabling online mode on your server.

Players with non-premium, or cracked accounts, will receive validation errors when joining servers with online mode enabled. Please note that this will only be the solution to your validation errors if you or someone joining your server is using a non-premium account.

Issues With Mojang's Servers

If Mojang’s authentication servers are offline, your account cannot be verified. When this occurs, you will need to wait until the authentication servers are back up again.

You can check the Mojang server status' with the Mojang Status page on their help site: https://help.mojang.com
