If you can create an account with an iPhone app, you should soon be able to delete it too.

Starting January 31, 2022, Apple will require apps to let you delete accounts created within that app. This will protect your private data and effectively block companies from letting you cancel subscriptions. But there’s a lot more to it than that. Apple’s new account deletion policy seems simple, but it changes a lot.

“You never know when or how an old account might get breached or what the consequences might be. If you reuse the same password for multiple accounts, a single leaked password could expose you in places you didn’t expect,” Michael X. Heiligenstein, publisher of the cybersecurity and privacy website Firewall Times, told Lifewire via email.

“And harder-to-change data, such as your address, phone number, or answers to security questions, can also be used to steal your identity and steal your finances.”
