When trying to login on a cPanel or WHM server, the browser never asks if I want to save the login credentials (user/password). This only happens with Chrome (I can save password perfectly with FF and Opera).
This issue with Chrome is not new, nor cPanel specific, it's actually an ongoing issue that cPanel has been attempting to work around for some time now. More on the issue here:

Suggested workaround by cPanel Developers:
Hope that helps.
