Log into your Spatial account on a web browser at app.spatial.io. Once you're logged in to your account, hover over your name in the top left corner, and select Profile.
From there, you may edit your Avatar's name and body type, and select the device you're using.
Click your Avatar to update your headshot using your webcam or an image. For best results, use a headshot with a neutral expression facing straight ahead.
When you're done, click Save.
