It would be nice to have a password complexity check (maybe this can be integrated in a plugin).

Think of all your editors or publishers who might use a very weak password, so hackers might modify or delete content (I assume that administrators are sensible enough to use a good password ).

So it should be possible to select at least following:
- Password min. length: _6_
You password MUST contain:
- digits [ ] min. number: _1_
- lower case characters [ ] min. number: _1_
- upper case characters [ ] min. number: _1_
- special characters [ ] min. number: _0_

It would also be fine if the plugin does not offer any configuration dialog and the user can add a hardcoded function to the plugin:

E.g.
// returns true of the password fulfills your needs
function check_password(pass_entered)
bool ok = false;
// add your check here and set ok=true if the complexity is ok
return(ok)

So anybody could modify the plugin according his needs.

A little inspiration (and inspiration only) can be found here :

Some random thoughts:

No client-server data exchange. The password should not be sent back to the server for testing. All testing should be done by javascript alone. The result of the test could be displayed / rendered by javascript DOM manipulation alone.

The module should compile the javascript tester script dynamically, based on settings in the module.

If it was made of wood I could probably hack this...

extensions.joomla.org/component/option,com_mtree/task,viewlink/link_id,2410/Itemid,35/

but it's made of code, so maybe someone else can do it.
