Let’s say you get locked out of one of your devices and can’t remember the password ID. Using your iPhone, call one of your account recovery contacts who is using his iPhone to get a shortcode that he will forward to you. Tap the number to open your account and you will be asked to create a new password for the account. Don’t be a smart guy and use passwords like, well, password, or your last name.
Instead, use a combination of letters, numbers, and special characters. And if you do forget it, trustworthy contacts are there for that. By the way, the selected trusted contacts must be an iPhone owner aged 13 and over. And remember, this feature won’t appear until you have iOS 15 installed on your device. While that means you can install the iOS 15 public beta and start using the feature now, there is no point in sacrificing the bugs and battery life that you will have to deal with until the final stable release of iOS 15 in comes on the market about two months.
