Auth failing - user detail log

Is there a way to see what username & password where attempted when the app tries to log into the ha server? and is there any minimal spec requirements for the app?

I’ve got some old mobile devices that I’m trying to setup as a dashboard but the companion app fails to log in with ‘wrong username / password’ and when selecting the show password button in the app it errors with app required key not provided @ "data['client_id']".

I’m copying and pasting the username & password so know they’re correct, and if i use the same copy/paste in chrome on the same device it logs in fine, but the password field on the app is behaving strange; type in the password manually its basically only storing every second key. (i.e. 123456 becomes 246) so guess the paste isn’t working either (even though it appears to)
