Forgot my password

Hi there- my HA is running perfectly fine. but i forgot the password to go the UI.

i have tried connecting directly to the pi with a keyboard and screen. i see login… after keying in root, i then tried core authentication reset --username "with the username i remember but it gave me a failed error… FATA{0000] Error while executing rootCMD: unknown flag: --username…

i dont know any other methods and the links to the authentication is not getting me anywhere.

No worries, i managed to figure out the username and changed the password. thanks

how did you figure out the username? just remembered or can it be lookup somewhere?
