OAuth 2.0 - a dead simple explanation

[@jgoebel]

What do you think about this video? Let me know in the comments below. FYI: I had to re-upload this video because the old one had an audio issue. Sry for that.

[@waynecam2007]

this is brilliant

[@JoshComninellis]

VERY helpful. The clearest explanation I’ve been able to find on the topic. Thank you!

[@abhinahitokab3879]

Great stuff , thanks alot, please keep updating with new changes in oAuth,

[@alastairtheduke]

Great slow and clear explanation without cutting any corners, thank you

[@jgoebel]

Glad you liked it

[@philipparker5291]

Really clear explanation. Thanks a bunch!

[@alexpato4]

One of the best explanations about OAuth, thanks a lot!

[@carolineroy7992]

Thank you a lot ! I have to implement an authorization code grant for my personal project and the service doc was really confusing. Great explanation, you saved me 🤗

[@jgoebel]

Great to hear!

[@Mr.D4yz]

Great video! Short and simple explanation to share with colleagues and not look like an alien trying to explain it.

[@talatkuyuk6556]

It is really really good explanation. Thank you....

[@jgoebel]

Glad you liked it!

[@nohjrd]

Brilliant video and a really clear excellent explanation.

[@winspyre]

Excellent explanation.

[@jgoebel]

Glad it was helpful!

[@GigGigJigolo]

Welcome back! May I ask what tool you used to illustrate this video?

[@jgoebel]

I used After Effects for this

[@psylo1841]

You are creating amazing content! Please keep doing it!

[@jgoebel]

thx

[@ThePomelo09]

awesome explanation and presentation, new sub :)

[@jrblackify]

Excellent video! Not verbose and tedious like many others, and very informative. The only small nit I have: at 4:45 you say "we will learn about the response type in a minute" but then I don't think you ever talk about it. You do talk about Grant Types which are related (I think?) but not response type.

[@andreaskaudel3047]

Great stuff ! Thank you very much !

[@jgoebel]

Glad you liked it!

[@SandeepJan]

amazing video.. are you planning to redo the other grant types similar to your old playlist or this is a one off update

[@jgoebel]

was thinking about that. I am a bit time-crunched atm and also the new animated videos did not get that many views. So not sure if I will continue this format or focus on different content

[@grltrader]

Great video!

[@jgoebel]

Glad you enjoyed it

[@haidersyed6554]

9:10 the client may get refresh token but did you miss access taken part ? When is access token granted by the authorization server ?

[@jgoebel]

forgot to mention it, but you always get a refresh token and you optionally get a refresh token

[@k.deepak]

Great content, as always! Could you please share the name of the software you used to create these animations?

[@jgoebel]

After Effects

[@ribbenyms]

Good video but really bad EQ, I had to really crank down 125HZ cut to keep the floor from shaking :/

[@adrian333dev]

Really well explained ⭐⭐

[@jgoebel]

Glad it was helpful!

[@thongtranlequoc688]

Thank you very much. Your video is amazing

[@jgoebel]

thx

[@nwaformicah433]

Nice video and I think of using Oauth for the project am working on now but I want to ask a question. Did I need to pay or add my credit card before I can use it?

[@jgoebel]

OAuth is just a standardized framework and quite a few Identity Providers offer it as a service. Whether or not that is free depends on the provider

[@nwaformicah433]

@@jgoebel Thanks so much I just want to use user email for sign in, him or her into my express server. I have a full stack app, mern

[@johanneskingma]

Question: what is the difference between a framework and a protocol?

[@jgoebel]

Oh there are very long-winded debates about this 😅 It seems a bit fuzzy. So a framework is more composable, i.e. the spec does not stipulate every single detail (e.g. in OAuth 2 the spec does not say how exactly the access token has to look, it leaves it somewhat open). A protocol is a more stricter rule set that leaves little to no things open (e.g. HTTP or TCP)

[@yapayzeka]

perfecta explanation

[@jgoebel]

Glad it was helpful!

[@haidersyed6554]

How does Google know that the client has a backend ? What if Google issued client secret when there is no backend ? I got confused I think client credentials part needs more elaboration

[@jgoebel]

When you register the third party app, you can register a confidential or public client. If you have a backend, you can keep a secret safe, i.e. you have a confidential client

[@mm333-e1t]

Yooo welcome back !!!

[@jgoebel]

thx

[@sigge.g2193]

thanks!

[@jgoebel]

Welcome!

[@jano.5485]

Dumb question not directly related to OAuth... if you can extract anything out of a mobile application for example, how would such an application communicate with its backend securely? Surely you could also just extract those authentication secrets?

[@jgoebel]

In a mobile app you would not ship any credentials in the app itself when you put it on the app store. That's why you need a backend that the app communicates with that holds the client secret for the OAuth flow. The moment the app is used, of course then you can store cookies, tokens etc on each user's device. But the whole point is that you must not have any secret in your app when you submit it to the app store. Or you do dynamic client registration. But then every mobile app installation is its own third party which would be strange

welcomee

[@Saurabh12129]

This makes me believe I am not dumb.

[@jgoebel]

Most explanations on the Internet are just overly complicated and don't explain the why

2:37 "if the 3rd party application can keep data secret" what is that supposed to mean?? if it its trustworthy? if it stores data at all?? All the effort to make a video and then you throw things like that in there ... I don't understand video makers anyway

[@jgoebel]

This is explained in the section confidential vs public clients at 3:06
