00:00:00,300 --> 00:00:03,420
Now, let's try to recap what we have discussed in this section.

2
00:00:03,630 --> 00:00:09,990
We started this section with the discussion around authentication provided what is its role in the spring

3
00:00:09,990 --> 00:00:16,290
security architecture and what are the scenarios that we need to go for an option of customizing this

4
00:00:16,290 --> 00:00:22,770
authentication provider so that we can skip off adhering, heading to the user details and user details

5
00:00:22,770 --> 00:00:24,330
of these user details.

6
00:00:24,330 --> 00:00:26,970
Manager contact provided basically security.

7
00:00:27,060 --> 00:00:33,780
We also looked at the definitions of authentication for the authentication manager and the methods inside

8
00:00:33,780 --> 00:00:40,980
them and observed that authentication provider has two methods authenticate and supports, whereas authentication

9
00:00:41,000 --> 00:00:44,310
manager has only one method, which is authenticate.

10
00:00:44,640 --> 00:00:50,790
The difference between authentication provider and authentication manager is only supports method was

11
00:00:50,790 --> 00:00:57,870
that we also discussed about the important interface, which is authentication followed by principle

12
00:00:58,140 --> 00:01:04,560
and how they are similar to user details and also looked at how the user details will become with the

13
00:01:04,739 --> 00:01:11,400
authentication object in the scenarios where we are using the default authentication provider, which

14
00:01:11,400 --> 00:01:15,400
is the authentication provider from the spring security framework.

15
00:01:15,900 --> 00:01:23,070
After that, we also looked into the provider manager and the authentication provider, which are default

16
00:01:23,070 --> 00:01:27,110
implementations of authentication manager and authentication provider.

17
00:01:27,390 --> 00:01:34,350
And so it's been security and we saw like how provider manager handles all the providers configured

18
00:01:34,350 --> 00:01:35,970
inside my application.

19
00:01:35,970 --> 00:01:45,030
How would we look each provider by provider and how it performs authentication authenticate method in

20
00:01:45,270 --> 00:01:46,230
all the providers.

21
00:01:46,530 --> 00:01:53,490
Finally, we enhanced our application to have a custom authentication provider and perform authentication

22
00:01:53,670 --> 00:01:55,930
using it without any issues.

23
00:01:56,130 --> 00:02:00,810
With that, we are concluding the authentication provider concept.

24
00:02:00,990 --> 00:02:04,640
If you have any questions, please post in the comments section.

25
00:02:04,680 --> 00:02:05,330
Thank you.

26
00:02:05,340 --> 00:02:05,850
And Mike.
