I can stream to my origin server using ffmpeg without a login even if RTMP Publishing is set to Require password authentication.
Why?

E:\Work\ffmpeg\bin>ffmpeg -re -f dshow -audio_buffer_size 10 -channels 1 -i audio="Microphone (Realtek High Definition Audio)" -strict -2 -codec:a aac -channels 1 -b:a 8k -ar 22050 -f flv -rtmp_buffer 0 -rtmp_live live rtmp://audioroot/live/1
