Why isn t my Apple Face ID working?<\/div>\n
Make sure that your face isn't blocked Make sure that your eyes, nose, and mouth are fully visible to the TrueDepth camera. By default, Face ID doesn't work if anything is covering your mouth and nose. If you're wearing a face mask and have already set up Face ID with a mask,* make sure that your eyes aren't blocked.<\/div>\n
