Register a new YubiKey/FIDO2 hardware security key or TOTP authenticator app (Google/Microsoft Authenticator) under Facebook Meta Accounts Center. Delete all existing security keys and standard SMS 2FA numbers registered by the previous owner.

Add a fresh, unlinked primary email address (e.g., dedicated Outlook/ProtonMail created solely for handover) inside Meta Accounts Center. Promote it to Primary, confirm access via code, and permanently remove the seller's original registration email address.

Inspect Meta Security Center for legacy trusted contacts, linked WhatsApp numbers, or backup phone credentials. Purge all prior entries to prevent recovery requests submitted through identity verification challenges.

Execute 'Log out of all sessions' inside Facebook Security Settings. Terminate all active logins across Android, iOS, Windows, and Web browsers, initiating Meta's 24-hour session security cooldown before confirming escrow release.
