SPEAKER: Cybersecurity is extremely
important in our day and age.

2
00:00:03,780 --> 00:00:07,300
We're all constantly hearing about
massive hacks and data breaches.

3
00:00:07,300 --> 00:00:10,590
So what can we do to be as
secure as possible online?

4
00:00:10,590 --> 00:00:14,040
Here are three tips from Harvard's
computer science professor.

5
00:00:14,040 --> 00:00:15,960
First, use a password manager.

6
00:00:15,960 --> 00:00:18,870
You've probably seen your phone
offering you a safe password when

7
00:00:18,870 --> 00:00:20,190
signing up somewhere.

8
00:00:20,190 --> 00:00:21,120
Use it.

9
00:00:21,120 --> 00:00:24,510
This way, you'll never have the same
password for different websites.

10
00:00:24,510 --> 00:00:28,640
And even if one of them gets
compromised, the rest will be safe.

11
00:00:28,640 --> 00:00:31,670
Next, use two-factor authentication.

12
00:00:31,670 --> 00:00:33,740
This is done to confirm
that you are actually

13
00:00:33,740 --> 00:00:37,880
by sending you a one-time code
on your phone or your email.

14
00:00:37,880 --> 00:00:41,640
It gives hackers a much smaller
chance to log into your account.

15
00:00:41,640 --> 00:00:44,640
And, finally, use end-to-end encryption.

16
00:00:44,640 --> 00:00:46,590
This is the safest way to communicate.

17
00:00:46,590 --> 00:00:49,770
But the option to do so
is not always explicit.

18
00:00:49,770 --> 00:00:52,370
For example, on Zoom, you
have to go to the Settings

19
00:00:52,370 --> 00:00:55,130
and manually turn on the
end-to-end encryption.

00:00:55,130 --> 00:01:00,520
