2. When using social media apps, privacy settings is a "must" thing you should know

Each social media app has its own privacy settings, but there are some commons among all of them. Here is a list of actions you can take to protect yourself:

• You can decide who can see your profile, send you direct messages or comment on your posts by adjusting your account privacy settings.

• You can report hurtful comments, messages and photos and request they be removed.

• Besides “unfriending”, you can completely block people to stop them from seeing your profile or contacting you.

• You can also choose to have comments by certain people to appear only to them without completely blocking them.

• You can delete posts on your profile or hide them from specific people.

3. Sign out all of your accounts after using public devices

After using public computers or laptops, you should log out of any account you use. This includes logging out of email, social media accounts, and any other account you may open.

• Simply closing the tab is not enough. If someone gets on the computer immediately after you are done, they may still be able to get into your account. And once they have access, they can take control of that account by changing passwords.

• Once they have control, they can impersonate you online by making fake posts and comments that make you look bad. Plus, once you lose access to an account, it can be difficult and time-consuming to regain control.
