If you are in a situation where you cannot log in to your Facebook account because you can’t get to your Facebook page, its password has changed without your knowledge, or that you have forgotten your primary email address or password, that situation is an indication that in some way, your account has been compromised.
Do not let Facebook to Keep you logged In
One of the most common reasons people’s account got hacked or in other words, accessed without their knowledge, is that they let Facebook to keep them logged in when they use a shared computer that your friends or anyone else can use. When you do a Facebook.com log in, there will be a check box for if you want to let Facebook to “keep me logged in“.
If you tick that when you log in, the next time you visit Facebook.com it will automatically sign you in even if you have completely closed the internet browser or even restarted the computer. Well, that is a pretty convenient feature but only if you can be sure no one else you don’t know of can access to that computer, laptop or mobile devices such as a phone or tablet where you sign in to your Facebook account.
If you have ever logged in to your Facebook account in any public computer such as those in a cyber cafe, airport, Starbucks, school or work places with the keep me logged in button ticked, you should change and reset your Facebook account’s password immediately before it’s too late.
Use @facebook.com if you do not remember your original email
When you first signed up for a Facebook account, you were given a field to fill in your desired Facebook username.
Well, that username would be used as your permanent Facebook profile’s URL address and a personal Facebook email account (not entirely an email account). For example, if your username is peterfreddy6677, your Facebook URL would look like www.facebook.com/peterfreddy6677 and your personal Facebook email account would be firstname.lastname@example.org.
This particular email can also be used to sign in to your account just in case if you have forgotten your main email account you used to register with Facebook. That said, from the example above, you can sign in using peterfreddy6677 or email@example.com as your username.
It is also worth noting that any email message sent to this @facebook email account will be forwarded to the primary email address on your Facebook account. You can opt to enable or disable this feature by going to your Facebook page, Settings from top right corner of the page, Email, and then check or uncheck Use your Facebook email.
Use Phone Number to Log In to Facebook
If you have previously given your phone number to Facebook when you signed up for your Facebook account, you can use the phone number as your username to login to your Facebook. Skip the zeros or any symbol (such as +) before the country code when you enter your phone number. This will come in handy when you have forgotten both your primary email address and your Facebook username. Phone number is also your last option to retrieve and reset your Facebook account’s password if you have no access to your primary email address at all.
If you haven’t already register your phone number with Facebook, you can do so now by going to your Facebook page, Settings from the drop down menu at the top right corner of the page, click on the Mobile section, and then enter your phone number as instructed on the screen. You must confirm your phone number by entering the code sent to that phone number before it can be usable in Facebook. Once it’s confirmed, you can log in to your Facebook with your phone number.
You can also opt to receive alerts by SMS text whenever someone sends you a message in Facebook. If you are worrying if Facebook would flood your SMS with alerts, you can control the daily limit of texts and time of the day Facebook can send you SMS alerts.
