Minecraft Won't Log Me In

When i try to log into minecraft to play, it says invalid and my username or password is wrong, i know it is correct because ive been using it for years, i tried reseting my password and it says successfully reset your password, then i log in and it says its wrong and i reset again making sure i write down exactly what i type and it still won't let me log in, ive tried uninstalling and re-installing minecraft as well as having other launcher version, it just won't let me log in, servers and stuff are up and i waited for 40 minutes then tried to log in and still it won't let me get on it says its wrong but i know its right -----> Help???
