WEBVTT 0 00:00.480 --> 00:05.460 Hey guys, welcome to 100 Days of Code. And today we are on day 29, 1 00:05.760 --> 00:08.760 where we're going to be building a password manager. 2 00:09.270 --> 00:11.610 So we're going to be doing this using tkinter. 3 00:11.880 --> 00:16.620 And the real inspiration for this project came about because I was trying to 4 00:16.650 --> 00:16.880 register 5 00:16.880 --> 00:21.880 for a website where it asked for a password that was just insanely 6 00:22.460 --> 00:27.020 complicated, something along these lines, or it has to be really long. 7 00:27.020 --> 00:29.510 It has to include lots of different things, 8 00:29.840 --> 00:34.130 it can't match your previous passwords. It just has a whole bunch of rules 9 00:34.610 --> 00:39.610 and I really struggled coming up with a password that actually match all of their 10 00:39.680 --> 00:42.110 requirements. And by the time that I came up with it, 11 00:42.410 --> 00:44.420 I've already forgotten what the password was. 12 00:45.080 --> 00:49.070 One of my favorite blogs is Coding Horror by a guy called Jeff Atwood. 13 00:49.250 --> 00:52.100 And you might not know him by name, 14 00:52.130 --> 00:55.520 but you will actually have used something that he's made. 15 00:55.730 --> 00:58.130 He is one of the founders and original creators 16 00:58.130 --> 01:00.350 Stack Overflow 17 01:00.380 --> 01:03.230 which I'm sure by now you're well familiar with. 18 01:03.650 --> 01:08.650 And even he was talking about how password rules are just really terrible. 19 01:09.290 --> 01:13.730 They're so long and they're so complicated and they've even inspired 20 01:13.760 --> 01:16.400 a really good XKCD comic, 21 01:16.820 --> 01:20.270 which essentially tells the truth that through 20 years of effort, 22 01:20.270 --> 01:23.570 we've successfully trained everyone to use passwords that are hard for humans to 23 01:23.570 --> 01:27.380 remember but easy for computers to guess. This is the crazy state of things. 24 01:28.340 --> 01:31.640 So we're going to be creating a program to combat that. 25 01:31.880 --> 01:35.690 And it's going to be called MyPass, our password manager, 26 01:36.230 --> 01:40.220 and we're going to use it to store and generate passwords. 27 01:40.700 --> 01:43.820 For example, if I wanted to create an account on App Brewery, 28 01:44.300 --> 01:48.770 then I enter the name of the website so that I know what this password is for, 29 01:49.130 --> 01:53.990 I put in my email, and username is already prepopulated in my password 30 01:53.990 --> 01:58.670 manager. And then all I have to do is to either come up with a password 31 01:58.700 --> 02:03.500 that is hopefully not terrible, but I can obviously never remember, 32 02:03.830 --> 02:08.830 or I can use the builtin generate password to just generate me a very complex, 33 02:09.530 --> 02:14.530 very long password with all of the required numbers and symbols and all of that. 34 02:15.200 --> 02:18.170 And once I'm done with that, then I can click add, 35 02:18.620 --> 02:21.830 and I get a popup asking me if this is okay. 36 02:22.490 --> 02:24.980 And if that all looks good, then I click Yes 37 02:25.190 --> 02:28.610 and that data gets added to a text file, 38 02:28.640 --> 02:30.530 which I have on my computer. 39 02:30.980 --> 02:35.750 So this is not an internet-based service and you keep everything locally on your 40 02:35.750 --> 02:36.583 computer, 41 02:36.770 --> 02:41.180 which some people feel is a lot safer than using a third-party service 42 02:41.180 --> 02:43.400 like LastPass or whatever else. 43 02:44.420 --> 02:48.350 So this is what we're trying to build and it's got some really neat features. 44 02:48.680 --> 02:52.280 For example, it's got some basic validations. So if you, for example, 45 02:52.280 --> 02:56.690 leave one of the fields empty and you click add, you get a popup that tells you, 46 02:56.720 --> 03:01.030 please don't leave any of the fields empty. Or if you generate a password, 47 03:01.210 --> 03:06.210 then you can actually immediately use it by pasting it. What's happening behind 48 03:06.250 --> 03:09.130 the scenes is as soon as I click on generate password, 49 03:09.460 --> 03:14.440 then my password is saved onto my clipboard and I can paste it into the password 50 03:14.440 --> 03:16.810 field on the website I'm trying to sign up for. 51 03:18.340 --> 03:20.320 This is what we're going to be building today. 52 03:20.410 --> 03:23.410 And it's going to use everything you've learned about tkinter 53 03:23.830 --> 03:26.680 and we're going to be learning some new things that you can do with 54 03:26.680 --> 03:28.930 tkinter as well. Once you're ready, 55 03:29.020 --> 03:31.600 head over to the next lesson and let's get started.
