When you’re wearing your Apple Watch (Series 3 and later), you can use it to securely unlock iPhone (models with Face ID) when you’re wearing a face mask.
Whether you’re out shopping or trying to find someone in a crowd, use the Walkie-Talkie app to get in touch with just a tap. Add friends, then manage when you want to talk.
If you no longer use the email address that’s associated with your Apple ID, you can change it. You won’t lose access to your contacts, purchases, or other account information.
