Access the object of one form from another form

Question

The window application has two forms. First is the login form "Login", containing the usual login details, username and password. The username and password are entered in the textboxes- txtUser and txtPassword. After authentication the second form "Form1" opens. How do I access the username entered in txtUser in "Login" so that I can display in "Form1"?
Please help.
