Don't be afraid! In this video we walk through what exactly app registrations, enterprise apps and service principals are without really talking that much about Azure AD :-)

This is by FAR the best explanation of what can be a very confusing topic that I have seen. You out did yourself here John, thank you!

[@raylicon9525]

The best description ever. Microsoft training is as their name suggests, "soft" plus weak and worthless in comparison.

[@gdr1174]

When I first started to take an interest in technology it was through reading incredibly dry text books from the library. Thank god for people like John who make the constant learning journey much more accessible and enjoyable 👍

[@mromar2724]

This has to be the best explaintaion on workings of AAD I have ever seen. Thank you

[@50PullUps]

I am JUST beginning to comprehend this material while learning the basics of working with the Microsoft Graph API.

[@Tnub2]

Wow, great content, John! When you showed how the Enterprise Apps are only listing the Service Principals and that you would have one SP in every AD that wants to access the app - that was really an "AHA-moment" for me. Thank you so much for this excellent explanation <3

Most condensed version of a complicated topic

[@dscoduc]

Great video, thank you. Are you planning on doing a deeper dive into this topic? There are many more pieces to this part of Azure that are difficult to understand, such as the difference been App Registration tokens and Enterprise Application tokens, SAML (RP) configurations, API access permissions, etc.

Thank you soooo much!!!

[@davidaranda2528]

Finally, someone who can explain this whole process in a way that actually makes sense. Great video, keep it up!

[@sgphillips101]

Brilliant training from John on a subject I have always had problems grasping. I watch alot of John's courses, he is an amazing teacher.

[@kimicheng5611]

I was totally lost when I was watching this video for the first time. After I learned OAUTH2 and other concepts here and there for several days and come back to watch again, all the contents in this video are crystal clear and really well organized and presented. Thank you so much.

[@sachingoyal22]

Thanks so much. This video is now 3 years old, still explains the concepts like no other video does.

[@lysajane3643]

Wow! Absolutely brilliant. It doesn’t quite come through like this when reading the documentation over and over again. TY for explaining the Svc Principal and the difference between App Reg and Enterprise Apps.

[@helennamannila4464]

Congratulations - what has always been a really confusing area has now become crystal clear. I had to watch it twice to make sure I thoroughly understood it (and will probably have to watch it again if I need to remind myself a few months down the line). But you have achieved what the Microsoft doc could not. (Also had much-needed research into OAuth 2 in the process, so win-win!) Thank you :)

[@michaelr1154]

After 3 years, i keep coming back to this video. Love your work as always John!

[@emmiauranen]

I can't believe you made a video of this over three years ago! So glad you did, because now it's more understandable. BTW, your handwriting is so much better these days 😄

[@gherghinamarian3576]

A lot of things got clear in my head after watching this video! I like your teaching style, very clear, concise, and one that keeps your attention. I'll surely watch other videos. Thank you John, appreciate it!

[@sabokunogaraa]

I'm really amazed. The Microsoft docs were making me run in circles but this video was more than enough to understand such a complex topic

[@asmiles9057]

Woah! I read through so many different sites trying to understand these topics without any success. This video cleared up everything for me. Thank you for creating this.
