 The high-performance NVENC backend for the selkies-gstreamer WebRTC interface is only supported in GPUs listed as supporting `H.264 (AVCHD)` under the `NVENC - Encoding` section of NVIDIA's [Video Encode and Decode GPU Support Matrix](https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new). If your GPU is not listed as supporting `H.264 (AVCHD)`, add the environment variable `SELKIES_ENCODER` with the value `x264enc`, `vp8enc`, or `vp9enc` in your container configuration for falling back to software acceleration, which also has a very good performance depending on your CPU.
 
-The username is `user` in both the container user account and the web authentication prompt. The environment variable `PASSWD` is the password of the container user account, and `SELKIES_BASIC_AUTH_PASSWORD` is the password for the HTML5 interface authentication prompt. If `SELKIES_ENABLE_BASIC_AUTH` is set to `true` for selkies-gstreamer (not required for noVNC) but `SELKIES_BASIC_AUTH_PASSWORD` is unspecified, the HTML5 interface password will default to `PASSWD`.
+The username is `ubuntu` in both the container user account and the web authentication prompt. The environment variable `PASSWD` (defaulting to `mypasswd`) is the password of the container user account, and `SELKIES_BASIC_AUTH_PASSWORD` is the password for the HTML5 interface authentication prompt. If `SELKIES_ENABLE_BASIC_AUTH` is set to `true` for selkies-gstreamer (not required for noVNC) but `SELKIES_BASIC_AUTH_PASSWORD` is unspecified, the HTML5 interface password will default to `PASSWD`.
 > NOTES: Only one web browser can be connected at a time with the selkies-gstreamer WebRTC interface. If the signaling connection works, but the WebRTC connection fails, read the [Using a TURN Server](#using-a-turn-server) section.
