WEBVTT 0 00:00.300 --> 00:03.390 All right, guys, welcome to a brand new module. 1 00:03.420 --> 00:08.640 And in this module, we're going to tackle the topic of authentication. 2 00:09.030 --> 00:15.290 And it's something that is often thought of as incredibly complicated, but it doesn't have to be. 3 00:15.330 --> 00:21.750 And we're going to take it step by step from beginning to end so that you get an overview of the entire 4 00:21.750 --> 00:24.510 process of setting up authentication from scratch. 5 00:25.230 --> 00:27.610 So why do we need to authenticate? 6 00:28.110 --> 00:35.730 Well, as we're creating our website or web app for users to use, then these users are going to start 7 00:35.730 --> 00:38.430 generating data in the website. 8 00:38.730 --> 00:40.710 They might like certain posts, 9 00:40.920 --> 00:43.080 they might interact with other users, 10 00:43.230 --> 00:46.880 there might be messages created or recipes created. 11 00:46.920 --> 00:49.860 There's always going to be some user data created. 12 00:50.400 --> 00:57.150 And in order to associate those pieces of data with individual users, we need to create an account 13 00:57.150 --> 01:02.610 for each user. So that they would sign up to our website using a username and a password 14 01:02.910 --> 01:09.450 and we would essentially create kind of like an ID card for them to uniquely identify them on our database 15 01:09.750 --> 01:14.520 and to save all of the data that they generate onto that account. 16 01:15.060 --> 01:20.670 So the next time that they come back onto the website, they'll be able to use their username and password 17 01:21.000 --> 01:28.110 and log in to our website and be able to access all of those possibly private pieces of information. 18 01:28.470 --> 01:33.510 So this way, you don't end up with everybody being able to see, you know, what private messages you're 19 01:33.510 --> 01:37.280 sending around on Facebook or see your direct messages on Twitter. 20 01:37.650 --> 01:39.030 So that's pretty simple. 21 01:39.270 --> 01:45.420 Now, the other reason why you might want to add authentication to your website is to restrict access 22 01:45.630 --> 01:49.770 to certain areas of the website depending on the status of the user. 23 01:50.040 --> 01:57.570 So, for example, if you were Spotify or Netflix and you charge a subscription for accessing certain 24 01:57.570 --> 02:03.210 parts of the website, then once the user pays, you have to update their account in your database to 25 02:03.210 --> 02:09.930 say that they have paid and they'll be allowed to access the TV shows or songs that they're entitled 26 02:09.930 --> 02:10.230 to. 27 02:10.770 --> 02:16.550 So those are some of the reasons why you might want to add authentication to your website. 28 02:16.860 --> 02:21.030 But authentication can be done in a number of ways. 29 02:21.030 --> 02:27.690 Creating a website where we sign up and log in users seems simple enough, but the difficult part of 30 02:27.690 --> 02:32.750 authentication comes from how secure you're going to make your website. 31 02:32.840 --> 02:38.100 But so we're going to learn how to progress from essentially a website that's basically secured with 32 02:38.100 --> 02:45.210 a Cheeto to something that is a lot more serious and more consistent with industry standards of good 33 02:45.210 --> 02:46.810 security on a website. 34 02:47.160 --> 02:50.600 So the structure of our website is really, really simple. 35 02:51.000 --> 02:59.760 It has a homepage which has two buttons that allows you to either go towards register or go towards 36 02:59.760 --> 03:00.300 login. 37 03:00.480 --> 03:06.120 And once the user has been registered or logged in and they have been authenticated, then they are 38 03:06.150 --> 03:08.630 able to access the secrets page. 39 03:09.150 --> 03:15.090 So I've kept the remainder of the website pretty simple because we're going to be focusing on a pretty 40 03:15.090 --> 03:16.130 complex topic. 41 03:16.230 --> 03:23.010 So I've created some starting files for you to download so that we can focus our efforts on learning 42 03:23.010 --> 03:27.160 authentication and not get distracted by things like bootstrap and styling. 43 03:27.600 --> 03:33.750 So once you're ready, head over to the next lesson and download the starting files, and then we're going 44 03:33.750 --> 03:35.940 to get started with authentication. 45 03:36.270 --> 03:37.350 So I'll see you there.
