Its a bug, Try to login and wait for an hour it fixes it self. If it still doesnt fix try to log in 3 times After 3 incorrect login attempts, a lockout is placed automatically by Mojang's systems on your network to protect accounts against brute force attacks to gain access. This lockout is automatic, lasts for 3 hours, and cannot be overridden. Wait 3 hours, don't log in at all. It it doesnt fix itself then I suggest changing your password and trying again.
