00:00:03,020 --> 00:00:08,660
Welcome to section number twelve on authentication and data security in this section and we're going

2
00:00:08,660 --> 00:00:13,550
to focus on locking down all of the data for the task manager app.

3
00:00:13,550 --> 00:00:17,360
Right now all of the API endpoints are publicly accessible.

4
00:00:17,360 --> 00:00:23,170
That means anyone can come along and do something like delete every single piece of data in the database.

5
00:00:23,240 --> 00:00:24,680
And obviously that's a problem.

6
00:00:25,160 --> 00:00:29,780
So in this section we're going to lock all of that down putting it behind authentication.

7
00:00:29,780 --> 00:00:35,660
That means users will need to sign up and log in before they're going to be able to do something like

8
00:00:35,660 --> 00:00:41,060
create a task or fetch a list of their tasks by forcing users to log in.

9
00:00:41,060 --> 00:00:47,080
We're also going to be able to setup a relationship between a user and the tasks they've created.

10
00:00:47,180 --> 00:00:54,290
That's going to make sure that user 1 can't delete a task or even see a task created by user number

11
00:00:54,290 --> 00:00:55,130
two.

12
00:00:55,130 --> 00:01:01,820
So in this section we're going to talk about authentication passwords security database data relationships

13
00:01:01,880 --> 00:01:02,730
and more.

14
00:01:02,750 --> 00:01:03,680
Let's jump right in.
