The function GUI.Label() returns a string value that should be the new value of your username field.
Right now, you’re not actually changing the value of username. In other words, it’s never being assigned to.

username = GUI.Label(new Rect(826,251,70,40) , username);

Avoid using the same variable names locally in functions as the global ones. Inside IEnumerator, change username and password to something like user and pass. Not much can be done with this much of information.

Also, you are not setting username to anything at all. Change GUI.Label(new Rect(826,251,70,40) , username); to username = GUI.Label(new Rect(826,251,70,40) , username);
