Facebook has got your number – even if it’s not your number [nakedsecurity]

Do you value your Facebook account? Have you linked your phone number to your Facebook account? You could lose access to it if you aren’t careful, according to James Martindale, who discovered a worrisome Facebook authentication vulnerability. Facebook encourages you to give it your phone number “to help secure your account”, and you can link multiple numbers to your account. That means that you – or anyone with access to your number – can take control of your account.
