Question on use of sign in and sign out

[NancySemple]

You state not to use these words as nouns or adjectives. However, there may be the case when you have to. For example, the name of a dialog box. In this case how should the words be used? I am thinking "Sign-in dialog box" and "Sign-out dialog box". Is this hyphenation what you would recommend? [Enter feedback here]

Also, if you have to use a single word to indicate that someone has successfully signed in, what would the phrasing be - "Successful signin" or "Successful sign-in"?
