Hiding the login

Can I hide the login prompt from viewers of the site?

• Hide it in the template by using the same text and background color. (sic)
• Change the text 'menu_login:' in settings/language to a '.' or '*', and the roll-over text too.
• In the template, move the login() function somewhere far less obvious.
• Remove the login function from the template, then access it directly typing the url - (the url may be different)
  

• Create a hidden page and place this code on it.

Code: <form id="login" action="index.php" method="post"><input type="hidden" name="login" value="true"><input type="text" name="passwd" value=""><input type="submit" value="Login"></form>
