Why Minecraft can't verify your username and how to fix it

The "Failed to Verify Username" error means Minecraft's servers could not confirm that the account name you entered matches an active account, or that your device is allowed to play on that account. This usually happens because you typed the username wrong, your internet connection dropped during login, your account was migrated to a Microsoft account and you're still using the old name, or your device needs to authenticate with Microsoft's servers again.

The fix depends on which of these is actually happening. Start with the simplest checks first — they solve the problem in most cases.

Key Takeaways

  • Check that you typed your username exactly as it appears in your account settings, including capital letters and numbers, because Minecraft usernames are case-sensitive.
  • If your account was migrated to Microsoft, you must log in with your Microsoft email address, not your old Minecraft username.
  • Restart your internet connection and the Minecraft launcher, then try logging in again, because temporary connection problems often cause this error.
  • If you still cannot log in after these steps, sign out completely from the launcher, clear your browser cookies, and sign back in through the Microsoft login page.
  • Check the Minecraft server status page to confirm the authentication servers are online before troubleshooting further.

Verify you typed your username correctly

Open your account settings on the Minecraft website or in the launcher and look at exactly how your username is spelled. Minecraft usernames are case-sensitive, which means MyUsername is different from myusername. If you have a number in your username, make sure you typed the number and not the word — for example, Player2 is not the same as PlayerTwo.

Type your username into the login field character by character, or copy and paste it directly from your account settings to avoid typos. Then try logging in again.

Check whether your account was migrated to Microsoft

Minecraft accounts created before 2020 were originally standalone accounts that used a Minecraft username to log in. Since 2020, all accounts have been migrated to Microsoft accounts, which means you now log in with a Microsoft email address instead of your Minecraft username.

If you see the error after trying to log in with your old Minecraft username, try logging in with the email address linked to your Microsoft account instead. You can find this email by going to account.microsoft.com, signing in, and looking at the account details. If you are not sure which email is linked to your account, try the email you used when you first created the Minecraft account.

Restart your connection and the launcher

Close the Minecraft launcher completely. Restart your internet connection by unplugging your router for 10 seconds, plugging it back in, and waiting for it to reconnect. Open the Minecraft launcher again and try logging in.

This step fixes the error when your device lost connection to Microsoft's authentication servers during login, or when your internet connection is unstable. If you are on a mobile device, turn airplane mode on for 5 seconds, then turn it off, and try logging in again.

Sign out and clear your login cache

Open the Minecraft launcher and click the profile icon or account menu in the top right corner. Select "Sign Out" and wait for the launcher to fully close the session. Close the launcher completely.

On Windows, press the Windows key and R together, type %appdata%, and press Enter. Look for a folder called .minecraft and open it. Find the file called launcher_accounts.json, right-click it, and delete it. On Mac, open Finder, press Command and Shift and Period together to show hidden files, navigate to ~/Library/process Support/minecraft, and delete launcher_accounts.json.

Reopen the Minecraft launcher. It will ask you to sign in again. Use your Microsoft email address and password, and log in through the Microsoft login page that appears in your browser. Do not use a saved password — type it fresh.

Check the Minecraft server status

Visit the Minecraft status page at status.mojang.com to see whether the authentication servers are online. If the page shows that the "Minecraft Launcher" or "Authentication" service is down, the error is not on your end — you will need to wait for Microsoft to bring the servers back online. Check back in 30 minutes to an hour.

If the servers are online and you have tried all the steps above, the problem may be specific to your account or device. At this point, visit the Minecraft support page at support.minecraft.net and submit a report with the exact error message you see.

Frequently Asked Questions

Does "Failed to Verify Username" mean my account was hacked?

Not necessarily. The error usually means a login problem, not a security breach. If you are worried your account was compromised, change your Microsoft password and check your account activity at account.microsoft.com. If you see logins from places you do not recognize, enable two-factor authentication on your Microsoft account when ready.

Can I use my old Minecraft username to log in anymore?

No. All accounts now require a Microsoft email address to log in. Your old Minecraft username still exists and is tied to your account, but you cannot use it as a login credential. You must use the email address linked to your Microsoft account.

What if I forgot which email is linked to my account?

Go to account.microsoft.com and try signing in with the email addresses you think might be linked. If none of them work, visit support.minecraft.net and describe the problem. Microsoft support can help you recover access to your account.

Does this error mean I need to buy Minecraft again?

No. The error is a login problem, not a license problem. Once you log in successfully, you will have access to the game you already own. You do not need to purchase it again.
