How do I deactivate my Apple Account?

You can indeed.

You may temporarily deactivate (recommended) or permanently delete (use with caution).

Learn more about both; and when ready, start the process for either from here:

“Deactivation” is temporary and reversible.

Although the loss of use and access while “Deactivated” is indeed total.

“Deletion” is permanent.

You don’t say why you wish to deactivate your Apple Account but be aware that if you do so you lose access to all content or subscriptions you paid for in the past in the past, including music, photos, videos. So think hard before deciding.

And it bricks still-associated devices.

Particularly those device lacking purchase receipts, or where the receipts were stored in the now-deleted account.

I know I always store my safe’s combo in my safe …

… after all, it’s VERY important. 😉

I’ve personally deleted 3x accounts, and Apple is VERY thorough at 1) making sure that you have copied the “never mind” code …

… 2) giving you plenty of time to “change your mind” …

… AND 3) explaining the consequences of failing to sign out of ALL devices.

Yep. And I’ve answered a more than a few questions about reviving now-bricked gear post-deletion, too. 🤷‍♀️
