The security breach in Facebook : Among the 50 million accounts that were hacked also Mark Zuckerberg's account

The security breach on Facebook: Among the 50 million accounts that were also breached by Mark Zuckerberg and the vice president of operations, Cheryl Sandberg.

Because of this, there was a mass forced disconnection from Facebook And there was a need to reconnect!!
If you are disconnected from the application and are required to re-enter, then you are on the list of "casualties"

Explain the breakout and how to protect yourself !

The engineers found a weakness in the "Preview" button that allows viewing the profile as it looks to other surfers. The problem is that this tool revealed a digital key that allows people to access Facebook from the device without the need for a password, meaning that they identify with Facebook using the key. An attacker could use the firewall to log on to an account that does not belong to it. The workers realized that 50 million people had been hurt by this breach
What to do?

To see if someone has already signed in to your account, go to the Login and Security page and check the list of devices you're connected to, if you're unfamiliar with a foreign device. If you've identified one, just delete it with a click.

Password - Facebook say there is no need to change password because the loophole has been blocked but it is always advisable to change password for each case. We recommend a different password from other accounts, integrated characters and not short.

2-Step Verification - Enabling 2-Step Verification requires you to enter a special code that you will receive in the message even after you have already entered a password in an attempt to connect. This prevents an attacker from accessing your account if it only has a password because it must physically hold your device to access. Please note that recently in the media it was revealed that Facebook uses a cell phone number that you submitted for two-stage verification for advertising purposes. So for your consideration.
