1
00:00:00,160 --> 00:00:06,560
chances are that you've got a staggering number of online accounts for everything

2
00:00:04,080 --> 00:00:10,400
from your weird craft store to that fitness forum that you joined to get

3
00:00:08,240 --> 00:00:14,480
advice on your workout program that only lasted for a couple of weeks

4
00:00:12,320 --> 00:00:19,760
and you've probably also grown weary of having to sign up for a new account over

5
00:00:17,440 --> 00:00:23,920
and over and over again so whenever you see one of those super

6
00:00:21,680 --> 00:00:29,519
convenient buttons that says sign in with facebook or google or soon sign in

7
00:00:26,960 --> 00:00:33,600
with apple you eagerly click on them but how do they work and are you possibly

8
00:00:31,599 --> 00:00:38,079
giving away too much of your personal information so these buttons use a

9
00:00:35,920 --> 00:00:43,280
protocol called oauth which takes advantage of the fact that services like

10
00:00:40,320 --> 00:00:49,440
google and facebook have enormous user bases and many of those people use them

11
00:00:46,559 --> 00:00:53,760
as primary services for communication and they already store their personal

12
00:00:51,600 --> 00:00:58,480
details in them like their names and email addresses the kind of basic stuff

13
00:00:56,399 --> 00:01:02,559
that many sites would require for your account activation regardless

14
00:01:00,879 --> 00:01:07,119
of how you sign up so what oauth does is it allows whatever

15
00:01:05,680 --> 00:01:14,080
third-party site you're trying to register for to access your google or

16
00:01:10,320 --> 00:01:16,479
facebook account but not in its entirety

17
00:01:14,080 --> 00:01:20,479
instead the site is only allowed to view certain

18
00:01:17,439 --> 00:01:22,560
pieces of your account typically a name

19
00:01:20,479 --> 00:01:27,040
and email at the minimum and maybe a profile picture

20
00:01:24,080 --> 00:01:31,360
so oauth manages this by first checking that you are actually signed in to your

21
00:01:28,960 --> 00:01:37,759
google or facebook account then assigning a special access token and a

22
00:01:34,799 --> 00:01:42,960
secret which is basically a password to the third party site so that google or

23
00:01:40,479 --> 00:01:48,479
facebook know only to give that site access to certain parts of your profile

24
00:01:45,680 --> 00:01:54,640
now an important note here is that oauth doesn't reveal your actual facebook or

25
00:01:51,520 --> 00:01:57,360
google account password so shady sites

26
00:01:54,640 --> 00:02:01,680
can't access or modify more information than they explicitly tell you that they

27
00:01:59,119 --> 00:02:05,759
will and that you authorized them to do one key though is to double check what

28
00:02:04,159 --> 00:02:10,239
permissions you're giving the site because many of them will allow you to

29
00:02:08,000 --> 00:02:15,040
modify what parts of your profiles they can access so that you can prevent a

30
00:02:12,480 --> 00:02:19,200
situation like you know some site that you use for promo codes constantly

31
00:02:17,120 --> 00:02:23,840
posting embarrassing coupons to your facebook timeline for the most part this

32
00:02:21,599 --> 00:02:27,840
single sign-in scheme works well and is quite convenient but of course in the

33
00:02:25,760 --> 00:02:32,800
world of tech someone is always trying to find a way to do it better and apple

34
00:02:30,400 --> 00:02:39,120
thinks it indeed has something superior with its new sign in with apple service

35
00:02:36,239 --> 00:02:43,280
so first up is integration with face id and touch id in an effort to give the

36
00:02:41,120 --> 00:02:47,920
sign in process a boost in both convenience and security so that's

37
00:02:45,440 --> 00:02:52,720
pretty swell but it's not necessarily even the main selling point here one of

38
00:02:50,319 --> 00:02:57,840
apple's big innovations is that sign in with apple will actually permanently

39
00:02:55,360 --> 00:03:02,560
hide your email address from third party services this is important because in

40
00:03:00,080 --> 00:03:05,920
some ways an email account is kind of like

41
00:03:03,360 --> 00:03:11,519
a master key because it serves as a master account with password reset

42
00:03:08,319 --> 00:03:13,920
capabilities for many other accounts so

43
00:03:11,519 --> 00:03:18,400
you don't want it just floating around out there looking like a juicy target

44
00:03:16,480 --> 00:03:24,959
so instead of giving it out like free candy apple will generate a random new

45
00:03:22,239 --> 00:03:30,319
anonymized email address that is linked to your account for every service that

46
00:03:27,680 --> 00:03:34,640
you sign up for this has the benefit of improving your anonymity online

47
00:03:32,480 --> 00:03:40,000
and also making it harder for unscrupulous sites to sell your actual

48
00:03:37,440 --> 00:03:43,680
email address to third parties or to spam you

49
00:03:41,360 --> 00:03:46,720
additionally apple claims that because they make their money selling you

50
00:03:45,280 --> 00:03:52,720
iphones and macs and monitor stands and whatnot your

51
00:03:49,840 --> 00:03:58,400
sign ins across multiple services won't be used to track your activity by

52
00:03:55,360 --> 00:04:00,080
contrast google and facebook do keep

53
00:03:58,400 --> 00:04:05,040
track of what third party sites you've signed into with their single sign-on

54
00:04:01,760 --> 00:04:05,840
solutions to help serve you relevant ads

55
00:04:05,040 --> 00:04:11,599
so that's apple's pitch and it sounds pretty good honestly so

56
00:04:09,680 --> 00:04:15,920
hopefully they'll stick to their promise not to track you

57
00:04:13,200 --> 00:04:20,959
especially because they're going to make sign in with apple a requirement for any

58
00:04:18,560 --> 00:04:24,960
app on the app store that also uses single sign-in options from their

59
00:04:22,479 --> 00:04:29,360
competitors just apple being apple
