You have to remember what you entered when you set it up.
But if you can’t, see Authentication - Home Assistant
I install Home Assistant from Umbrel . It no have page to set up username , so I can’t get username and password
Well then ask umbrel. When you set up ha for the first time you enter a new username and password. If you didn’t get that, then they have done something weird that no one here can know.
Did you manage to find a solution? I’m having the same issue
Update: once I installed and unistalled Home Assistant in umbrel just as test but the user and password were still saved somewhere in the system.
I solved connecting via ssh to umbrel:
ssh [email protected]
(your ip)
umbrel password
docker exec -it homeassistant bash
hass
I got an error and exit using ctrl+c
hass --script auth --config /config change_password existing_user new_password
(your user and new pass)
I didn’t remeber what my user was but at this step I could test some possible username
exit
docker restart homeassistant
