phone number recycling

Phone number recycling covers what happens when a carrier reassigns a disconnected number to a new owner, and why that matters for account security. The tagged discussion walks through the risk that password resets, SMS verification codes, and messaging-app logins stay tied to the old number, so a stranger can receive codes meant for the previous owner. It points to the U.S. carrier aging period and the routine reuse of numbers, then recommends auditing accounts and updating or removing the phone number before the old line goes dead. The focus is practical account hygiene rather than Windows-specific configuration.
