Configuring Facebook for a More Secure
Social Networking Experience
Settings
Settings are available under

Arrow.
General Account

Name
You can change the name
of your Facebook account
to just about anything;
however, Facebook’s rules
require that the name be
your actual name. In Facebook’s own words, “Facebook is a
community where everyone uses the name they go by in everyday life.
This makes it so that you always know who you’re connecting with and
helps keep our community safe.” Facebook, and likely every other
social networking site, does not make a serious effort to verify
anyone’s identity.
The alternate name feature can be used for an unmarried name so
friends can locate you (e.g., Susan Smith (Jones) or a nickname or
diminutive of your given name). Once a name change is made, you
are required to wait a period of time before another name change can
be made.

3. Facebook presents a preview of how your name
change will appear on your timeline.
4. Check an acceptable variant, enter your password,
and click Save Changes.
Email
When you created your Facebook account, your registration was verified through email or text message. That
means that Facebook sent an email message to the email address you provided. That email message had a web
link you had to click to verify your email address.
This is also where you change your email address if the address you registered with Facebook is disabled or
retired for any reason or if you want to receive emails in a different mailbox.
To change your email, from the General Account Settings menu:
These Facebook configuration recommendations are based upon best information available at the time of publication
but are not a guarantee of social networking safety. Facebook may have instituted configuration changes since publi-
cation. Users must exercise caution whenever interacting with social media.
1. Click Contact. 2. Click Add another email or mobile number.
3. Enter the new email address in the box.
4. Click Add.
5. Enter your password and click Submit.

must exercise caution whenever interacting with social media.
6. Click Close.
7. Facebook will send an email message to the new
email address confirming the change and a
notification of the change to the email address of
record.
8. Check for email at the new email address. It will
look like this. Click Confirm.
9. Return to the General Settings area. If you see this
message, the changes were successful.
Delete an Existing Email
Facebook will not allow the removal of an email if it is the primary email or it is the only email. If you do not have
a secondary email, you must add one. Follow the instructions in the section immediately above to add a
secondary email address. Then, to delete an email address, from the General Settings menu:
1. Click Contact.
2. Click Remove next to the address you want to
remove.
3. Click Save Changes. If you have chosen to
remove an email address and save changes,
you will receive an email at the removed email
address notifying you of the change.

Passwords
Passwords, secret elements of authentication, are on the front line of defense preventing people and automated
tools from illegally accessing your online accounts. Therefore, your choice of password and the frequency with
which you change it are important security considerations.
A password, however, need not be limited to a word. It can be a passphrase. A passphrase is a string of characters
that form a phrase. An example might be, "The song remains the same" or "I’ll see you on the dark side of the
moon". Passphrases are generally easier to remember than complex passwords and more likely to survive a
dictionary attack than is a password.
Guidelines for passwords to avoid, especially if you are a public figure or in a situation where much of your
personal information is in the public domain, include:
 Your name or any permutation of your name
 Your user ID or any part of your user ID
 Common names
 The name of any relative, child, or pet
 Your telephone number, social security number, date of birth, or any combinations or permutations of those
 Vehicle license plate numbers, makes, or models
 The school you attended
 Work affiliation
 The word "password" or permutations including "password" prefixed or suffixed with numbers or symbols
 Common words from dictionaries, including foreign languages
 Common dictionary word permutations
 Names or types of favorite objects
 All the same digits or all the same letters or letter sequences found on keyboards (e.g., QWERTY)
1. Click Password.
2. Enter your current password.
3. Enter your new password or passphrase.
4. Re-enter it for verification.
5. Click Save Changes.

Security Settings
Security Settings are available under the Facebook Configuration Arrow.
Login Alerts
This is an effective means to identify attempted compromises to your Facebook profile. When accessing your
profile, after correctly entering the username/password combination, Facebook checks for the presence of a
cookie on your computer. That cookie identifies the browser as one from which you have accessed Facebook
before. If the cookie is found, the login proceeds without further interaction.
If the cookie is absent or incorrect, Facebook will ask the user if information about the browser should be saved
AND sends a text message or email to the addresses of record indicating a login from an unknown browser.
If you elect to use text messages, you will be required to provide Facebook with the number of your mobile device.
This presents a separate issue. See the section labeled Who Can Look Me Up.
If this browser is unrecognized, you will encounter a Facebook challenge asking if you want to Remember
Browser. Do not save that browser information unless you are using a computer you have control over
and will use again. If by chance you mistakenly opt to save the browser or there is a browser you have previously
saved but know you will not use again in the future, you can delete that browser by following the instructions in the
section Recognized Devices.
Login Alerts is not double authentication. If the correct username/password combination is entered, the
user will be allowed access to the profile. The defensive benefit of Login Alerts is the email or text message
notifying you of the access. If you receive a login alert and did not log in, you should immediately change your
password and take immediate steps as outlined in the sections Recognized Devices and Where You’re Logged In.
Login Alerts will not work if your browser is configured to refuse cookies or if your browser clears its
cache when it closes. If your browser is set to refuse cookies or clear cache when exiting, it is best to leave these
settings as they are and not use the Login Alerts feature.

1. Click Login Alerts.
2. Select Get notifications.
3. Select Email and click Save Changes.
4. Email notices will be sent to your email on file with
Facebook.
Login Approvals
This is the best way to prevent your Facebook account from being
accessed by someone else. Every login attempt to your Facebook
account will be interrupted and a code sent to the mobile phone on file
with Facebook. Only after that code is correctly entered into the
Facebook dialog box will the login proceed past the challenge screen.
The recipient of the text message has 20 seconds within which the
login must be completed or the code expires and the process must be
repeated.
Login Approvals, in conjunction with Login Alerts, will provide a
substantial level of protection against profile compromise.
1. Click Login Approvals.
WARNING—If you use Login
Approvals and retire the mobile
telephone number without first
updating the default number in
Facebook you will likely lock you
out of your account forever.
Facebook support might not be
able to help you.

2. Click Enable to start Login Approvals.
3. Click Enable to use the mobile phone on
file with Facebook.
4. Click Close.
5. Check your mobile phone for a verification
text message. Follow the instructions in
that message.
Your Trusted Contacts
Facebook friends you can contact to help you access your Facebook account if you get locked out are trusted
contacts. When you select your trusted contacts, they will receive notification that they are trusted contacts so
it is best to notify them prior to enabling this feature.
Trusted contacts should be people you know well - people you can trust. Your trusted friends should be
familiar with their responsibilities and understand that if they are ever called upon to assist you, they should
verify absolutely it is you asking for their assistance. Accordingly, email is probably a poor method of verifying
identity.
If at any time you decide you no longer want to have trusted Facebook contacts or you decide one or more of
your trusted contacts can no longer be trusted, you can make those modifications in the Trusted Contacts
area of security settings. Dropping a trusted contact does not generate an email message to the dropped
friend.
Regardless of the trusted contacts
you add or remove, you cannot
have more than five nor less than
three.
1. Click Your Trusted Contacts.
2. Click Choose Trusted Contacts.
3. Click Close.

4. Read this statement carefully.
5. Click Choose Trusted Contacts.
6. Add from three to five trusted friends. These
trusted friends must already be in your Facebook
friends list.
7. Click Confirm.
8. Review your choices and click Close.

Where You’re Logged In
This feature can be used to end any active Facebook session, including the one from which you are accessing your
Facebook account. Like Recognized Devices, this is more of a security audit tool than a security measure. Where
You’re Logged In will identify those computers from which you might not have properly logged out of
Facebook and can tell you if unauthorized access to your account has occurred.
A generally good security practice is to log out of any internet activity that requires a login; logging out is a specific
menu choice. Closing the browser or restarting the computer may be insufficient to fully log out. In some
circumstances, like accessing your Facebook account from a public computer or any computer that multiple people
use, simply closing the browser window will not log out of Facebook. Then, quite possibly, the next person who opens
Facebook from that computer could open to your account without being challenged for a password, giving them
unintended full access.
If you see a logged in browser and believe it to be an unauthorized connection you should:
 End the session associated with that browser,
 Change your password,
 Check Recognized Devices (see below) and remove any improperly authorized browsers,
 Recheck Where You're Logged In to verify that a new session was not started.
1. Click Where You’re Logged In.
2. Identify locations where you want to end activity and
click End Activity.
3. Verify that the session ended then click Close.

Recognized Devices
Not so much a security setting as it is an audit tool, the list of Recognized Devices shows you the browsers with
which trusted relationship have been established, the corresponding operating system of the machine the browser
is installed on and the date trust was established.
If you use Login Alerts then you should occasionally check this list and remove any browser you no longer use,
Recognized Devices you suspect are being used by others to access your account (this forces a login
notification email the next time anyone logs in), and browsers you may have mistakenly trusted.
If you see a browser listed as a trusted browser you do not recognize, you should:
 Remove the browser
 Change your password
 Check Where You're Logged In (see above) and end activity that is not you
 Recheck Recognized Devices to verify that a new trusted browser has not been added
1. Click Recognized Devices.
2. Identify the browser you want to un-
trust.
3. Click Remove opposite the unwanted
browser.
4. Verify that the intended browser is
about to be removed. The browser
that is about to be removed will have
Undo next to it.
5. Click Save Changes.

Privacy
Who Can See My Future Posts
Limiting the visibility of future posts to just friends is the best way to limit access to items on your timeline to
people with whom you have a trust relationship. This assumes that people on your friends list are in fact the
people they purport to be. Social engineering is a reality and Facebook does not make a serious effort to
verify the identity of new subscribers.
You can override this setting for an individual
post by clicking on the audience button and
selecting the desired option.
WARNING—Changes made here will
automatically and without warning
change the global setting of Who Can
See My Future Posts!!!
1. Click Who Can See Your Future Posts?
2. Click the selection down arrow.
3. Select Friends. 4. Click Close.

Limit the Audience for Old Posts on Your Timeline
This setting is powerful and immediate. Read the onscreen information and be sure you understand it before you
execute it. If you have opted to make all future posts visible to friends only then it does not make sense to not
make all past posts visible to friends only as well.
This option changes the setting on all posts already on your timeline so they are visible only to your friends. The
only change option is to friends. Once executed, the only way to undo the changes is by changing the Who Can
See This Post on each timeline item.
1. Click Limit the Audience for Posts You’ve
Shared with Friends of Friends or Public.
2. Click Limit Old Posts and the click Close.
The outcome of this option is that ALL past
posts on your timeline will be changed to
friends only. There is no means to select
any other outcome than friends.
Who Can Look You Up Using the Email You Provided?
and
Who Can Look You Up Using the Phone Number You Provided?
In order to create a Facebook account users must provide a valid email address or mobile number. The email
address is verified when Facebook sends an email that contains a link the user must click in order to demonstrate
the validity of the email address.
The mobile phone number is verified when Facebook sends a text message that contains a verification code and
that code is entered into Facebook a verification dialog.
However, these small steps of validation should not be interpreted to mean that Facebook user identities are
properly vetted. Anyone can use any of the free email providers to create a "single use" email address or one of
the available online disposable phone number sites to receive text messages. This creates circular verification - a
fake email address or mobile number to verify a fake social media account.
If you have enabled Login Alerts using text messaging, login approvals, or code generator then you have provided
Facebook with your telephone number.

Do You Want Other Search Engines to Link to Your Timeline?
Your profile can be located using most internet search engines and parts of your timeline may be visible even to
those without a Facebook profile. By controlling this setting, you can reduce the possibility of your Facebook profile
being located by someone other than a Facebook user.
Users must bear in mind that, for some considerable but indeterminate period of time after the search capability is
turned off, residual records in a search engine will persist.
* Outside Search Engines re-
fers to search engines other
than the search capabilities pro-
vided within Facebook.
Regardless of how Facebook obtained your email or telephone number, it could be possible for any Facebook user
to locate your profile using only your email address or telephone number. This option should be turned off for both
contact methods.
1. Click Who Can Look You Up Using the
Email Address You Provided?
2. Change the setting to Friends (the most restrictive).
3. Click Close.
4. Execute the same steps for Who Can Look You Up Using the
Phone Number You Provided?
1. Click Do you want search engines
outside of Facebook to link to your
profile?

Who Can Send You Friend Requests?
Limiting the people who can send you friend requests to friends of friends provides a little extra assurance that a
friend request is coming from someone in your personal network. But be cautious! Accepting a friend request from
someone you do not know simply because they are a friend of a friend effectively pushes the burden of vetting new
requests to your friends; their efforts might not be commensurate with the level of verification and protection your
identity requires.
2. Deselect Allow search engines outside of Facebook
to link to your profile.
3. Click Close.
1. Click Who Can Send You Friend
Requests?
2. Click Friends of Friends (the most restrictive).
3. Click Close.
Download a Copy of Your Facebook Activity
You might find yourself in a situation where you would like to review all of your Facebook activity. Maybe you want an
archive of all images you’ve posted to Facebook but didn’t save to your local computer. Fortunately, there is a way to
do this without scrolling through innumerable Facebook pages. You can download to your local computer a copy of
your Facebook data.
A word of caution—DO NOT download a copy of your data to any computer you do not have total ownership of. Do
not download your data to a borrowed computer, a public computer like those you might use at a library, community
center or school, or your work computer.

Before you start the download process, consider the following:
 The time required to create your downloadable content could take hours or possibly days.
 The downloadable file could be many gigabytes or even many, many gigabytes. It will be large.
1. Click Download a Copy of Your Facebook Data.
2. Click Start My Archive.
(Clicking And More, at the bottom of this dialog
box provides, an idea of the content you can
expect. You can click this link while your down-
load is being prepared. A better plan is to look
at it before you start your archive. It will give
you insight into how big the download could
be.)
3. Enter your password to confirm your identity.
4. Click Submit.
5. Click Start My Archive.

6. Click Okay.
7. Periodically check your email account for a Facebook
notification that your archive is complete.
8. Review the statement in the Facebook
email and click the hyperlink.
9. Click Download Archive.
10. Enter your password and click Submit.
11. To complete the download process you will need to
navigate through several more dialog boxes. Follow
your operating system’s procedures for saving the
archive file.
The downloaded file will be compressed (e.g., zip). Save the contents of the compressed file to a new folder. Your
data will be arranged in more subfolders named for the content (e.g., profile, contact info, timeline).
