Step 5. Tap Deactivate your account at the bottom of the list.
Step 6. Locate the Deactivate link at the bottom of the page.
Before you get to that link, there will be a lot of information on the website, some of it rather useful. There’s a detailed explanation of what won’t be viewable (your display name, @username, and public profile), assurance that you can restore your account “for some time” if it was accidentally or wrongfully deleted, and a way to reactivate after 30 days or 12 months (useful if you’re being harassed and want to take a break from Twitter rather than delete your account entirely).
There are also links to change your name, utilize your present name with a different account, and download your Twitter data. This is usually a good idea before deleting any account.
