Meta says risk of account theft after phone number recycling isn't its problem to solve

Meta and others are being warned that mobile carriers' practice of recycling abandoned phone numbers can let new holders of those numbers hijack existing online accounts that rely on SMS-based one-time codes or phone-based password resets; a privacy consultant reported the issue to Meta (which rejected it as a bug-bounty case) and has filed a complaint with the Irish Data Protection Commission, while prior research confirmed many recycled numbers remain linked to active accounts.
