Can't log in web access

[cmooty73]

I'm not sure how I managed it, but I can't come up with a login/password that gets me in the web interface. I redid the SD card with the latest release, and I can ssh into the root account, can someone tell me how to reset the web interface username & password? I tried editing /tmp/sd/yi-hack/etc/system.conf and putting a username & password in USERNAME and PASSWORD. The file looked like this:

HTTPD=yes
TELNETD=yes
SSHD=yes
FTPD=yes
BUSYBOX_FTPD=no
DISABLE_CLOUD=no
REC_WITHOUT_CLOUD=no
MQTT=no
RTSP=yes
RTSP_ALT=no
RTSP_STREAM=high
RTSP_AUDIO=yes
SPEAKER_AUDIO=yes
SNAPSHOT=yes
ONVIF=yes
ONVIF_WSDD=yes
ONVIF_PROFILE=high
ONVIF_NETIF=wlan0
ONVIF_WM_SNAPSHOT=yes
NTPD=yes
NTP_SERVER=pool.ntp.org
PROXYCHAINSNG=no
SWAP_FILE=no
RTSP_PORT=554
ONVIF_PORT=80
HTTPD_PORT=8080
USERNAME=yi
PASSWORD=yi
TIMEZONE=
FREE_SPACE=0
FTP_UPLOAD=no
FTP_HOST=
FTP_DIR=
FTP_DIR_TREE=no
FTP_USERNAME=
FTP_PASSWORD=
FTP_FILE_DELETE_AFTER_UPLOAD=yes
SSH_PASSWORD=
CRONTAB=
but even after that and a reboot, I can't get into the webpage.

So I just tried yi with no password, and got in.
