How to keep your account from getting hacked
What for: So you don't get hacked.
If you use a short and simple password for your Facebook account, cybercriminals can guess it and hijack your account. A long and complex password is more secure. Use a strong password that:
- Is at least 8 and up to 20 characters long;
- Contains lowercase and uppercase letters, numbers, and special characters ($, @, etc.);
- Is not an actual word or easy-to-guess phrase;
- Is not the same as your passwords for any other accounts;
- Does not consist of information that strangers could easily find out (your name, date of birth, pet's name, and so forth — or those of your friends or relatives).
To change your password:
- Click your profile picture in the upper right corner of the screen;
- Open Settings & privacy;
- Open Settings;
- Select Security and login in the menu on the left;
- Select Change password under Login;
- Enter your current Facebook password;
- Enter a new strong password twice;
- Click Save changes.
What for: So you definitely don't get hacked.
Facebook can be configured to request a one-time code or physical security key when you log in to your account. That way, even if cybercriminals learn your username and password, they will not be able to use them without the one-time code or security key. The code is sent via SMS to your specified phone number or generated in a dedicated application (for example, Google Authenticator), while the security key is a small hardware device used to authorize your login.
To enable two-factor authentication:
- Click your profile picture in the upper right corner of the screen;
- Open Settings & privacy;
- Open Settings;
- Select Security and login in the menu on the left;
- Select Use two-factor authentication;
- If you see a warning about being redirected to another page, confirm this action;
- Enter the current password for your Facebook account;
- Select an additional verification method:
- By Text Message (SMS) to the phone number linked to your Facebook account or another number (for example, a SIM card on another device):
- Select Text message (SMS). If a phone number is not linked to your Facebook account, you will have to enter it and click Continue;
- In the window that opens, enter the code that Facebook sends to the phone number linked to the account;
- With a code generated by another app, such as Google Authenticator:
- To activate two-factor authentication using an app, select Authentication app;
- Scan the QR code that appears using your authentication app and click Continue;
- Enter the confirmation code from the authentication app;
- With a security key:
- To use this, click the corresponding button;
- Then insert your security key into your device and click Register security key;
- Confirm your choice.
Remember that a text message with the code can be intercepted by malware, which is why using a two-factor authentication app or security key is a safer option. Facebook can also use the phone number you linked to your profile for targeted advertising.
With two-factor authentication, you can log in to your account even if you lose your phone. For that, you need the recovery codes. To get them:
- On the same page, click Setup next to Recovery Codes;
- Click Get codes.
Each of the ten codes can be used only once. Write them down, copy them, or take a screenshot of them, and keep the information in a safe place.
How to defeat spammers and trolls
What for: To remove irrelevant comments.
By default, all Facebook users can leave comments under your posts, an ability that spammers and trolls often abuse.
To make sure that only your friends can comment on your posts:
- Click your profile picture in the upper right corner of the screen;
- Open Settings & privacy;
- Open Settings;
- Select Public posts in the menu on the left;

What for: To avoid unpleasant people.
If you want to stop a specific user from commenting on your posts, block that user. Blocked users will not be able to view your profile, leave comments under your posts, or send you private messages. In this case, the user will not know that you blocked them.

- Click Add to blocked list;
- Search for the user and click Block next to their name;
- Click Confirm, if the application asks you to.
How to hide posts from unwanted people
What for: So your posts will be seen only by those for whom they are intended.
You can choose who will see your Facebook posts. By default, they are visible to all of your friends. That can be inconvenient if you would prefer not to share your private life with some of them.
You may already have changed this setting and made your posts publicly available. Remember that information from your posts can be used against you. For example, information about your personal life can help telephone fraudsters to make up a convincing story in order to steal money from your bank accounts.
To configure the default visibility of your posts:
- Click your profile picture in the upper right corner of the screen;
- Open Settings & privacy;
- Open Settings;
- Select Privacy in the menu on the left;
- Select Who can see your future posts? in the Your Activity section;
- Open the drop-down list, click More and See All, and select the default group of users who will see your posts:
- Friends — posts are visible to friends only;
- Friends except… — posts are visible to all friends except those listed;
- Specific friends — posts are visible to friends on the list only;
- Only me — posts are visible to no one but you;
- Custom — more individual settings.
Remember that you can change the visibility of each individual post when publishing or after, without changing the default settings.
To restrict the visibility of your post when you create it:

- Open Settings & privacy;
- Open Settings;

- In the Your activity section, click Limit Past Posts;
- In the window that opens, click Limit Past Posts and confirm.
Downside: Your past posts will remain visible to anyone tagged in them, and their friends.

Cybercriminals can use information from your profile to do all kinds of unpleasant things. For example, they can bombard your phone with spam calls or text messages. Also, contacts from your social network profile, in combination with certain publicly available information about your life, can be a treasure trove for criminals aiming to defraud you financially. Detailed information about your job or interests helps them contrive persuasive stories.

- Select Only me in the window that opens, and click Done;
- Repeat for the rest of the items. Use the menu on the left to navigate sections with your information.
After configuration, you can see how your profile looks to other users:
- Open your profile;
- Click the three dots in the lower right corner of your profile header;
- Select View As. (To leave this mode, click Exit View As in the top right corner of the page.)
Downside: Your friends may have trouble locating your Facebook profile or contacting you by phone.

- Open Settings & privacy;
- Open Settings;

- Disable the Play a sound when each new notification is received and the Play a sound when a message is received options.
