WEBVTT 0 00:00.320 --> 00:02.780 All right, guys, well done for sticking it through. 1 00:02.810 --> 00:06.380 You are now on Day 5 of 100 Days of Code. 2 00:06.380 --> 00:09.380 And today I've got a fun project for you. 3 00:09.380 --> 00:14.930 And the inspiration for the project comes from the fact that all sorts of companies seem to be getting 4 00:14.930 --> 00:16.250 hacked these days. 5 00:16.250 --> 00:18.770 Everything from Ashley Madison to Verizon. 6 00:18.770 --> 00:22.910 Everybody seems to be really bad at keeping your password safe. 7 00:22.910 --> 00:31.160 So how can we make sure that these hackers who are in hoodies and wearing face masks don't get to you 8 00:31.160 --> 00:32.460 and your account. 9 00:32.700 --> 00:36.210 I also don't know why hackers are always portrayed like this. 10 00:36.210 --> 00:37.980 I mean, they're in their own house, 11 00:37.980 --> 00:44.250 they don't have to hide their face, but at least they're conscious of not spreading germs and staying 12 00:44.250 --> 00:44.580 warm. 13 00:44.580 --> 00:45.810 So that's good. 14 00:45.810 --> 00:49.320 But how do these hackers get into your account anyways? 15 00:49.350 --> 00:53.280 Well, one of the most common reasons is password reuse. 16 00:53.280 --> 00:59.720 Using the same password on 20 different sites, from Google to Facebook to Skype to Spotify, to all 17 00:59.720 --> 01:01.790 the random services that we sign up to. 18 01:01.820 --> 01:06.920 The problem is that when one of these sites get hacked, then the email and password combination you 19 01:06.920 --> 01:09.200 used to sign up is compromised. 20 01:09.200 --> 01:15.110 So all the hacker has to do is try out those credentials on a bunch of other websites and see if they 21 01:15.110 --> 01:15.740 work. 22 01:15.800 --> 01:20.090 So how do you know if your email and password is on a database somewhere? 23 01:20.090 --> 01:23.210 You can head over to haveibeenpwned.com. 24 01:23.210 --> 01:29.400 Notice the spelling there, and type in your email to see if it was involved in a website that had been 25 01:29.400 --> 01:30.000 hacked. 26 01:30.000 --> 01:39.510 So let's try an email here elon@tesla.com and it tells us, Oh no, it seems like this email has 27 01:39.510 --> 01:40.500 been pawned. 28 01:40.500 --> 01:48.210 And these were the websites which got hacked, potentially leaking this email and its associated password. 29 01:48.540 --> 01:53.510 I actually recommend you to try out your own email addresses right now and see which services you signed 30 01:53.510 --> 02:00.260 up to have been compromised, but if you want better security, then you'll actually need unique passwords 31 02:00.260 --> 02:01.820 for each and every website. 32 02:02.240 --> 02:08.570 And they should really be strong passwords, not 123456, or qwerty. 33 02:09.020 --> 02:12.110 If I just called out your password, please change it. 34 02:13.130 --> 02:16.340 Now, what we're going to be building is exactly that. 35 02:16.340 --> 02:22.830 We're going to be building a Password Generator, something that's going to generate strong passwords 36 02:22.830 --> 02:26.340 with letters, and symbols, and numbers. 37 02:26.520 --> 02:29.940 Firstly, it asks us how many letters would you like in your password? 38 02:29.970 --> 02:31.830 I would like 12. 39 02:31.860 --> 02:33.420 How many symbols would you like? 40 02:33.450 --> 02:34.500 I would like 2. 41 02:34.560 --> 02:38.250 And I would also like 2 numbers in my password. 42 02:38.250 --> 02:40.140 And then I hit Enter, 43 02:40.140 --> 02:49.070 and it gives me the password that it has generated with two symbols, two numbers, and 12 letters. 44 02:49.070 --> 02:53.210 So that's a pretty strong looking password, if you ask me. 45 02:53.240 --> 03:00.200 Now I can use this and update my password to something very strong and very secure. 46 03:00.320 --> 03:04.010 So this is what we'll be building by the end of today, 47 03:04.010 --> 03:09.590 but in order to do it, we first need to learn some new skills and new concepts. 48 03:09.590 --> 03:12.560 So head over to the next lesson and let's get started.
