Everybody knows how easily a Facebook account can be hacked if someone passwords get saved on a public computer.
There’s another way hackers can hack your count and you don’t even know it. Facebook also gave the option to change the password in what the social media giant thought is a protective measure to prevent what already was happening. This would have locked the real user out of their account, or to make matters worse, meant he would never have known his account had been hacked.
“This can be game over for your account,”
Facebook allows you to link multiple phone numbers to your account which is the basic problem. It doesn’t force you to remove old ones once you’ve stopped using them. Some person says he reported the issue to Facebook three months ago, but hasn’t yet done anything about it.
“There are situations where phone numbers expire and are made available to someone other than the original owner,” Facebook responded. “For example, if a number has a new owner and they use it to log into Facebook, it could trigger a Facebook password reset. If that number is still associated with a user’s Facebook account, the person who now has that number could then take over the account.
Facebook doesn’t have control over telecom providers who reissue phone numbers or with users having a phone number linked to their Facebook account that is no longer registered to them.”
The solution to this is quite obvious. You should immediately unlink any old numbers and email addresses from your account, by visiting settings and enable two-factor authentication along with enabling alerts about un recognized logins.
