Why is my Face ID unavailable?

Face ID may be unavailable due to various reasons. It could be a temporary issue with the device's software or hardware, such as a software glitch or a malfunctioning sensor. Other factors that could affect Face ID availability include wearing accessories that obstruct the face, changes in appearance (such as growing a beard or wearing glasses), or insufficient lighting conditions. Additionally, if the device has been recently restarted or updated, it may take a few moments for Face ID to become available again. If the problem persists, it is advisable to contact the device manufacturer or seek technical support.

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.
