How come it says invaild password??

[tntnns70]

Well, i was going onto my forum now,

I typed in my username which is : tntnns70. Then because i had just made my forum, i had made the password easy for me to type in. When i tried to login to the forum, it said invaild username or password? Do you know what is the problem?

When it is a completely new forum I am almost sure you typed a wrong password,
