Microsoft Account OAuth

[nelsonic]

Create Microsoft Auth so that I can authenticate with my Microsoft Account.

There are 1.4 Billion active devices running Windows 10 or 11:

This doesn't actually tell us anything about how many "On Microsoft" accounts there are ... gotta keep digging.

Statista is usually pretty reliable. Over 1.3 Million companies use Microsoft Office 365:

Some companies are much bigger than others.
But if conservatively each company has 100 people, then it's over 100 million people.

Wish I'd had time to do this while I was still doing my FinTech Consulting 🧑‍💻
[so I had a couple of MSFT accounts I could test with ...] 🧪

But it's all good; still know plenty of people we can call to help Beta Test this once it's working. 👌

@LuchoTurtle how confident do you feel about your Elixir skills? 🦄
Want to discuss this as a potential mini-project to work on? 💬
Much of the code can be "borrowed" from our existing repos as noted in the OP ⬆️
If we can get Microsoft Auth working ahead of the Auth Rebuild dwyl/auth#207 🔜
it would be awesome to include it as the "3^rd option" for people to authenticate to our App. 🤞

@LuchoTurtle please remember to leave comments on the issue you're working on through the day. 💬 🙏
And before you leave your desk/office git push your code to GitHub so that it's saved. 💾
I once lost a whole day's work when my I forgot to git push and my laptop died ... it was painful. 😢

[LuchoTurtle]

@nelsonic Sorry about that! Here's a quick rundown:

I spent most of the time actually battling with Azure Portal and understanding the flow of execution. I think I explained most of the setup needed so far in the guide I'm writing as I'm developing.
I realised that at first I was doing an implicit grant flow, where ID tokens and access tokens are returned directly from the /authorize endpoint instead of the /token endpoint.

But after scouring through the documentation, I realised this wasn't the best idea since it wasn't the most secure option when compared with the classic auth code flow thru OpenID Connect. So I had to redo some things to make it work.

And yes, I pushed most of my code to a different branch. I can't push directly to main because I don't have access and it's a protected branch 😉

[nelsonic]

Yeah, we don't tend to push to main.
Your microsoft-auth looks good. 👍

Does MSFT OAuth require you to use the Azure Portal? 💭
Not going to step on your toes while you're working. 👌
But make sure you share your progress as comments so you don't forget anything. ✍️

Does MSFT OAuth require you to use the Azure Portal? 💭

Yes it does! The same way you have to register an application when authenticating with Google, you ought to use Active Directory so our application has something to authenticate into 🤔 (AD is inside Azure Portal, amongst a myriad of other services).

[nelsonic]

Cool. That was my suspicion through superficial reading of the docs, but you spent a lot more time with them yesterday - to the point of being our new "expert"! - so thank you for confirming. 👌
