If you're logging into the Minecraft game client and you receive the error "Login failed. Invalid username or password.", this means that you're using incorrect login information. To learn more about this see below. If you need to change your password, visit our password change article. If you receive a technical error message when you try to log in to the launcher, please visit our technical help resources.
Players can in some cases experience issues accessing their accounts, and see the error message "Login failed. Invalid username or password.". This is a temporary issue, and waiting 30 minutes to 1 hour before attempting to log in again should solve the problem.
You may also want to change your password to something you haven't previously used. If you need to reset your password, please visit our article on account passwords. Note that changing your password multiple times will not resolve the issue.
If multiple failed attempts to log in are made in a row, you might have to wait 24 hours before the account can be authenticated again. If your problem is not resolved after 24 hours, please contact customer support.
