A recovery key is a randomly generated 28-character code that you should keep in a safe place. You can reset your account password by either entering your recovery key or using another device already signed in to your Apple Account. To ensure you have access to your account, you are personally responsible for maintaining access to the recovery key and your trusted devices.
