How to Secure an X/Twitter:

Secure the Linked Email
Ensure the email associated with the X account is secured. If no email was provided, move to the next step.

Update the Email
Request the previous owner to change the email to a new one that hasn’t been used before. New logins can’t change the email for 48 hours. Use this link to update it: Change Email

Change the Password
Log in and update the password using this link: Change Password

Remove the Phone Number
New logins can’t update the phone number for 48 hours. Remove it for now and add it later if necessary: Manage Phone Number

Clear All Sessions and Revoke App Permissions
Log out of all devices connected to the account and revoke any app permissions. Use this link: Manage Sessions

Enable Password Reset Protection and 2FA
This feature prevents others from sending password reset requests. Also, enable two-factor authentication: Manage Security

Additional Tips

1. Avoid changing the birthday, as this could trigger account locks.
2. Do not change the username, as it may get taken by a bot.
3. Usernames with fewer than 5 letters cannot be swapped.
4. Verify the original email (OGE) by comparing the account creation date with the first registered email.
5. Optionally, download account data to verify the OGE, though this takes 24-48 hours: Download Data
