Login issues

Long time since I had to directly connect to my raspberry Pi 4 home assistant on a screen attached to the Pi, not via Gui. This has hassio onstalled

I was asked for homeassistant login details. Everything I possibly thought could be the correct login has failed with Login incorrect

I can access the Home Assistant Gui via the app and web, and my logins work fine for that.

I guess there are 2 issues I have:

  1. I need to work out which user you use to login directly. It does not appear to be the idvfor the Gui login. I thought it might be the ssh user I set up but that fails too. I know this may be tricky but wondered if I need to be using an id that I use elsewhere in Home Assistant. I realise that this probably makes little sense as you do not know what user ids I have and how I have recorded their use. I can give outlines

    User for Ssh
    User for logging into Gui and web - definitely working there
    User for duckdns

  2. If I do identify which userid to use,and something has gone amiss with the password I have recorded against it,how do I reset?
