A "parameter" is an attribute of specific programming entities, such as method, SQL query, etc. This is code, making not so much sense, just needs a valid username to assign to the text box text property. You can simply make f2.Username an internal property, reading the value of private _username in its getter.

In a more general view, this is the popular question about form collaboration. The most robust solution is implementation of an appropriate interface in form class. Please see my past solution for more detail: How to copy all the items between listboxes in two forms[^].
