00:00:01,800 --> 00:00:05,340
Changing password. In this lesson, we will cover

3
00:00:05,490 --> 00:00:08,940
how you could change the user password. Either you

4
00:00:08,940 --> 00:00:11,130
are root and you force the user to change the

5
00:00:11,130 --> 00:00:14,400
password the first time you log in. Or if you are

6
00:00:14,400 --> 00:00:16,830
just yourself and you want to change your own

7
00:00:16,830 --> 00:00:21,570
password. You should change your initial password

8
00:00:21,600 --> 00:00:24,900
as soon as you login. Now, this is when your

9
00:00:24,900 --> 00:00:27,150
account is created for the first time in the

10
00:00:27,150 --> 00:00:29,850
system, and you log in with a password that's been

11
00:00:29,850 --> 00:00:32,820
given to you. Or sometimes what happens is a

12
00:00:32,820 --> 00:00:35,580
password is not given to you, you would just log

13
00:00:35,580 --> 00:00:38,370
in with your username, and it will automatically

14
00:00:38,370 --> 00:00:43,350
prompt you to put in a new password. To change a

15
00:00:43,350 --> 00:00:47,250
password that command is passwd is followed by

16
00:00:47,280 --> 00:00:50,700
the userid. The password is not the entire word

17
00:00:50,760 --> 00:00:57,030
is just passwd. It does not have o and r in

18
00:00:57,030 --> 00:01:01,560
it. So it's passwd userid and userid in

19
00:01:01,560 --> 00:01:06,840
my case is iafzal. When you hit enter, it will

20
00:01:06,870 --> 00:01:10,230
ask you for your old password or your existing

21
00:01:10,230 --> 00:01:13,830
password that you have. You provide that password,

22
00:01:14,790 --> 00:01:17,670
the next thing it will ask you is to put in your

23
00:01:17,670 --> 00:01:21,780
new password. You input your new password, it will

24
00:01:21,780 --> 00:01:25,290
reconfirm the new password for it. So it will ask

25
00:01:25,290 --> 00:01:28,140
you retype your new password. The reason that they

26
00:01:28,140 --> 00:01:30,840
asked for the second time is because if you have

27
00:01:31,170 --> 00:01:35,430
made a mistake in your earlier entry of adding new

28
00:01:35,430 --> 00:01:38,490
password, it will match to confirm that you have

29
00:01:38,490 --> 00:01:45,078
added the right password. Now, if you just type passwd

30
00:01:45,078 --> 00:01:48,330
while you are root, remember, it will

31
00:01:48,360 --> 00:01:54,330
change your root password. If you type passwd

32
00:01:54,330 --> 00:01:56,880
followed by userid, then it will change the

33
00:01:56,880 --> 00:02:00,780
password of that user. So let's log into our Linux

34
00:02:00,780 --> 00:02:03,720
machine through console and see how we could

35
00:02:03,720 --> 00:02:05,521
change our user password.

36
00:02:05,521 --> 00:02:14,014
[No audio]

37
00:02:14,014 --> 00:02:15,180
Here we have our Linux

38
00:02:15,180 --> 00:02:18,000
machine console, I'll just do a right click and

39
00:02:18,000 --> 00:02:22,230
open the terminal. I always like to make this

40
00:02:22,260 --> 00:02:28,440
terminal a lot bigger, make the window bigger. I

41
00:02:28,440 --> 00:02:31,950
could just simply drag and drop or I could simply

42
00:02:31,950 --> 00:02:35,460
maximize it by clicking here. Anyway, let's get

43
00:02:35,460 --> 00:02:39,030
into our changing password. So when I type

44
00:02:39,570 --> 00:02:46,650
passwd, followed by my userid it says, Only

45
00:02:46,650 --> 00:02:51,630
root can specify a user name. So only root has

46
00:02:51,630 --> 00:02:54,720
the rigth to specify the username. I'm not root, I'm

47
00:02:54,750 --> 00:03:00,960
being myself, who am I, whoami, I am myself, so all I

48
00:03:00,960 --> 00:03:04,950
will do is just put in just passwd command, not

49
00:03:04,950 --> 00:03:09,210
the username, I would hit enter and now it's

50
00:03:09,240 --> 00:03:12,240
asking me to change or to provide my current

51
00:03:12,240 --> 00:03:14,910
password. So I'm going to put in my current

52
00:03:14,910 --> 00:03:18,090
password. Now it's asking me for a new password.

53
00:03:18,180 --> 00:03:20,640
Now remember I'm gonna put in, this I'm just gonna

54
00:03:20,640 --> 00:03:24,780
put it 1234. And let's see what it says. It says, The

55
00:03:24,780 --> 00:03:27,870
password is shorter than 8 characters. So

56
00:03:27,870 --> 00:03:34,410
let's put in 12345678 and it says, The password fails

57
00:03:34,410 --> 00:03:39,450
the dictionary check. So now Unix or most of

58
00:03:39,450 --> 00:03:42,270
the operating system nowadays have this check

59
00:03:42,300 --> 00:03:44,850
where it looks for a dictionary and see if that

60
00:03:44,850 --> 00:03:48,480
password exists, of course to see if that word exists or not.

61
00:03:48,780 --> 00:03:52,380
So make sure you change you change the password to

62
00:03:52,380 --> 00:03:57,990
something that does not go with dictionary. I'm

63
00:03:57,990 --> 00:04:01,230
gonna change it to something different. There you

64
00:04:01,230 --> 00:04:08,040
go, see it took it. I'm going to reconfirm it and

65
00:04:08,460 --> 00:04:11,340
passwd: all authentication tokens updated

66
00:04:11,370 --> 00:04:15,330
successfully. So that's this command to change the

67
00:04:15,330 --> 00:04:18,480
password, and I want you to try that command, try

68
00:04:18,480 --> 00:04:22,170
couple of different types, different ways,

69
00:04:22,260 --> 00:04:25,079
become root and change your password by typing

70
00:04:25,079 --> 00:04:29,340
passwd iafzal, your username, and then login

71
00:04:29,370 --> 00:04:31,322
as yourself and try that command.
