Minecraft password supposedly wrong even though it's correct?

I bought minecraft today everything works at Mojave it says that I have it and everything but if I then open the minecraft lunch and do not log in with my correct password and email it says that it is wrong but I have been trying for an hour and have the password changed several times but it doesn't work what can I do?

It can take up to 24 hours until the account is fully activated and you can use it to log in.

If you change your password too often in a short time, the account can be blocked for 24 hours.
