Password Revealer - JavaScript Bookmarklet

While organising my bookmarks in Firefox I found this handy bookmarklet which I had forgotten about.



This bookmarklet, when clicked will pop-up any password which has been saved in your saved passwords list. It can be useful if you ever need to quickly find out the human readable text version of any password.

To use, simply add a new bookmark calling it whatever you like, I use "Reveal Pswd" and then copy this code into the Location, where a website's URL would normally go.

javascript:(function(){var s,F,j,f,i; s = %22%22; F = document.forms; for(j=0; j<F.length; ++j) { f = F[j]; for (i=0; i<f.length; ++i) { if (f[i].type.toLowerCase() == %22password%22) s += f[i].value + %22\n%22; } } if (s) alert(%22Passwords in forms on this page:\n\n%22 + s); else alert(%22There are no passwords in forms on this page.%22);})();

*Above code may not render correctly in feed readers, view blog article for correct code.

Enjoy.


Since posting this
I have found out that the Firefox Add-on "Web Developer Toolbar" has an option to "Show Passwords" so this JavaScript bookmarklet is redundant if you use this.

If you have the Web Developer Toolbar installed, to reveal passwords in a saved form all you have to do is this: "Forms -> Show Passwords" and what appears as circles or asterisks will change to normal text, revealing the saved password.
