When storing passwords in protected HTML files, I have routinely set the text to black on black so that the passwords cannot be read by people wandering by, and also so that they are not readable when printed. Some wikis, don't allow black on black text, so here is another cheesy alternative... create a hyperlink that pops up the the password, which is trivially encoded to stymie the passers-by:
<a href="javascript:alert(String.fromCharCode(112,97,115,115,119,111,114,100));">?</a>
Here is a snippet to URL-encode a password using a Javascript console:
var p="password"; var s = ""; for (var i = 0; i < p.length; ++i) { s += (i>0?",":"") + p.charCodeAt(i) }; s;
