How to protect your X / Twitter account while you are alive

There is no way to name someone in advance: X's deceased-user process works with an estate representative or a verified immediate family member, and only to deactivate the account.¹

The license to use X's software cannot be assigned, gifted, sold, shared or transferred to anyone without X's express written consent.²

Under the X Handle Marketplace Terms, X retains ownership of a handle it transfers, and the recipient gets only a limited, revocable and non-transferable right to use it. X may reclaim such a handle at any time, for any or no reason.³

X may reclaim a marketplace handle that is not used in a way that contributes meaningfully to the platform, and a business-use handle without a paid Transfer Price 30 days after the last active subscription day.³

X asks account holders to log in at least every 30 days to keep an account active, and accounts may be permanently removed for prolonged inactivity.⁴

A creator's share of revenue is not transferable between X accounts under either the Creator Revenue Sharing Terms or the Original Content Rewards Program Terms.^{5, 6}

Paid Services such as X Premium are non-transferable between X accounts under section 4 of the Purchaser Terms: a purchase applies only to the account used to buy it.⁷

The data archive is requested in Settings and privacy > Account > Your X data, after verifying identity with a code X sends to the email address or phone number on the account.⁸
