Install OpenWrt on Xiaomi Mi WiFi Nano

i follow instruction here https://openwrt.org/toh/xiaomi/nano
but i dont know the different between "your_admin_pass" & "newPwd=desired_root_pass"
i think, i have only 1 password????

curl -d "oldPwd=your_admin_pass&amp;newPwd=desired_root_pass" \ "http://192.168.31.1/cgi-bin/luci/;stok=<stok from browser url>/api/xqsystem/set_name_password"

Are you trying to change your password, to do that you need to verify your old password your_admin_pass and provide the new password desired_root_pass
