If you're logging into the Minecraft game client and you see the error message "Login failed. Invalid username or password." there are some options to try.
If you see a technical error message when you try to log in to the launcher, visit our technical Help resources.
“Login failed. Invalid Username or password.” error message
Players sometimes experience issues accessing their accounts and see this error message. This can be a temporary issue and waiting 30 minutes to 1 hour before attempting to log in again may solve the problem.
You may need to change your password to something you haven't previously used. If you need to reset your password, see Change or Forgot Password.
Note: Changing your password multiple times will not resolve the issue.
If your attempts to log in are unsuccessful multiple times, and you have already changed your password, you might have to wait 24 hours before the account can be authenticated again. If your problem is not resolved after 24 hours, contact Minecraft Support.
