It can take a few minutes for the updates to propagate to all users due to high demand. Apple has also released iOS 15.7.3 for iPhone users who have older devices, with the update offering security improvements.
Today's update introduces Security Keys for Apple ID, allowing for physical two-factor authentication that replaces the digital two-factor authentication used for Apple ID logins. There is a new Unity wallpaper, along with support for the second-generation HomePod.
Apple tweaked Emergency SOS to prevent accidental emergency calls. You can still activate Emergency SOS when holding down the side button with the up or down volume button, but a call won't be placed until the buttons are released.
