So, took a little-bit more of a dramatic approach. Removed Node-Red add-in, deleted /config/node-red directory, reinstalled via instructions, but to no avail. My config is using :
auth_providers:
- type: homeassistant
- type: legacy_api_password
But I still get prompted for userid/password, and login always fails.
Banging my head against the wall!

SOLVED: Deleted \hassio\config.storage directory, restarted and it gets automatically recreated. Puts you into new onboarding routine. Below article helped me.
