2FA can increase account security
Everyone should make sure their Facebook account is secure. It's important to take measures to protect your account from being hacked in an age when one wrong social media post could have devastating consequences. Enable two-factor authentication in Facebook. This is the easiest way to accomplish this. This means that every time you log into Facebook, you will need to use the password and code you received via SMS or another authenticator app like Google Authenticator.
We advise against sharing your phone number to Facebook. The company has previously allowed advertisers access to it. This is even though you only shared the number for security purposes. SMS-based two factor authentication is less secure than authenticator apps. Facebook allows you instead to use a physical security code, such as YubiKey to authorize your logins; this method is the most secure because it requires that you plug in the security code.
Facebook offers two-factor authentication. You can choose your preferred method to add additional security.
Next, set up alerts regarding unrecognized logins. To do this, go to Facebook's security settings page. Click Get alerts about unrecognized log-ins. You can also click on Authorized logins to see the devices that allow you to log in without using two-factor authentication. You should never allow any device to log into your account without these one-time passwords.
If you are locked out of your account for any reason, you can request that three to five friends receive a link via Facebook. This will allow you to recover your account. This can be enabled by clicking on Choose 3 to 5 friends that you want to contact if your account is locked out. You want to choose people you trust, who are also taking steps to protect their accounts.
