Code:

// Ok, very simple - for a game. No supercrunching or anything.
// I suppose we could start like this:
// A little complicated for a starter effort.
class supercruncher 
{
    int[][] pwStore = new int[3][4];
    supercruncher()
    {
        // conceptual - to be coded .....
        // We can unroll the loop for simplicity.
        for(pwStore.length) = passwordAsInt;
    }
    // ..... other code here
    if(checkPassword(int suppliedValue))
    {
        int loopControl = pwStore.length;
        do
        {
            // this next line is not correct
            if(pwStore.[--loopControl] == suppliedValue)
            {
                return true;
            }
        }
        while(loopControl > 0);
        return false;
    }
}

// This is ineffective - always checking is something one
// would place in the run loop in a game
if(password[0]==""+num1+num2+num3+num4)

Also, for four numbers - the way I have the array is incorrect. Several things in the code are indeterminate until you provide us some feedback....
