Thanks Marcus!
As soon as you said …
“on the widget there’s an option ‘Show Recover Password?’ with a dropdown of options to show, hide or show a direct link”
… it dawned on me that I had used straight-up shortcode to display LWA rather than use the widget – and then display that widget where I wanted.
Hence I did not realise I could just change those options as oppose to customising code.
Thanks for your help, much appreciated.
