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.
