I’m currently working on the improvements to allow saving passwords when no form submission can be detected. Perhaps this will help on this specific website - although I don’t have time to initiate a thorough investigation of the site right now, I’ll keep it in mind as an example to look into as we roll out to wider beta testing of the new password saving feature.
See Entry (password) saving improvements coming soon
PS: The element has no id - the text you mention is a placeholder
