Django admin expects users' passwords to be entered as SHA-1 hashes in the format {{{[algo]$[salt]$[hexdigest]}}}. Here is a tool which automates calculating the hashes on the client side.

What it does as of version 1.0 is:
 * searches each opened page for an {{{<input>}}} with {{{id="id_password"}}}, {{{class="vTextField required"}}}, {{{name="password}}}, {{{size="30"}}} and {{{maxlength="128"}}}, which is how the password field is defined in Django admin
 * when the password field loses focus, replaces its contents with a SHA-1 salted hash as Django expects
 * does not modify field contents if it's already a hash

You need to
 * use the Firefox browser
 * install the [http://greasemonkey.mozdev.org/ Greasemonkey] extension and restart Firefox
 * install the [http://svn.ambitone.com/ambidjangolib/js/djangopasswordhasher.user.js djangopasswordhasher.user.js] user script (click on the link: Greasemonkey should detect the script and display an "Install" button)

Pros:
 * works on all standard Django admin sites
 * nothing to install on the server side

Cons:
 * needs the extension on the browser
 * doesn't use a real password field ­­-- password entry is visible
