[@Babaelow]

IT really needs more teachers like you, that thought things through and make an effort to explain something as simple as possible and only as complicated as needed.

[@Gabzim]

Really appreciate you taking the time to leave an encouraging message

[@dirkb.2801]

This was truly a description of the OAuth flow that can be understood by everyone. Thank you!

[@camilos007]

Great video. You're the first one I've found that explains the 3 identities. The Resource Owner, The Client and Auth Server. Great job!

[@ryanplitt7102]

This video was exactly what I needed. I’m sad to say I’ve been a software engineer for a few years and have never really understood this until your video. Thanks!

[@tairatech]

This was a great introduction to OAuth, thank you Gabriel and keep up the great work.

[@robertlark7370]

Amazing stuff - really appreciate you explaining this in a simple way.

[@frankkrone973]

Well done! This is the first video I have found that explains the purpose before going into all the technical details.

[@isurucumaranathunga]

This is the best explanation that I have ever found. Thanks a lot

[@bobbywong82]

Super easy to follow. Stating the problem/context before going into explanation helps so much. Thanks!

[@domkatbess322]

My grandmother just understood this! Thanks.

[@martyg4939]

Its been awhile since I had to understand really what was going on with Oauth and this 15 minutes was superb in reconnecting what I knew but didn't remember. Thanks!!!

[@andreivicentiuhincu7457]

Great video explaining for beginners. I had to explain Oauth2 and OpenID Connect to my students, and this guide was very helpful for me to be more visual. Keep the content going ;)

[@ibbishariff]

This is a great video. I came across this video after watching few other videos on oAuth, but the way you explained was really brilliant. Other videos just touched the basic concept, but did not cover in-depth the way you've done in this video.

[@alihosseini4892]

The same here; not because the other videos aren't good, but because this video has great content and excellent presentation.

[@maulanaputro1966]

this is the exact explanation that im looking for, and you're doing it perfectly. keep this "explain A like im 5" series going!

[@Jay-sb2qj]

This was so well explained, thank you, Gabriel.

[@mkman]

I've been hearing the words OAuth for so long without knowing what it is. This video explains it really well in simple terms. Thank you

[@jcolby298]

Hallelujah. Finally someone that is really good at explaining complex technical topics in a simple, clear manner.

[@rhesustamarin]

great video gabe! the front channel and back channel were wow moments!

[@denys3211]

Best explanation ever. Well done, thank you!

[@laStar972chuck]

Tanks for the exlanation and quality drawing ! Really makes everything much clearer !!

[@kadidibwa968]

Indeed impeccable explanation... This deserves a standing ovation

[@boomboom-9451]

greatest explanation available in youtube. thanks

[@MrRossss1]

Best video I've seen on this. Great stuff. Thank you

[@connornorton7901]

Great explanation! I appreciate you breaking down the parameters of the request, so helpful.

[@johnalbertnajes]

Oh my, this really explained alot to me. This is so brilliant. I was struggling understanding oauth, and where to store my keys, now you gave me ALOT of ideas. ALOT. I know nothing *yet* about this oauth and you made me feel like a pro now. Thanks

[@Gabzim]

I’m really glad this was useful to you. I need to do part 2.

[@kennette2121]

Great explanation! You helped answer our question on the purpose of the authorization code + access token requirement. The Front and Back channel and client secret is an important aspect that we didn’t pick up on from the docs. Thanks!

[@Gabzim]

Glad it was useful! I’m working on part 2. I haven’t covered PKCE yet.

[@F2H16]

Hi Gabriel, this is an amazing rundown. Thanks for your time and effort.

[@jpakash1999]

The best explanation for oauth available on internet!

[@Vesture23]

Great content! Answered some of the questions I've been scouring the net for.

[@brokko_le3]

Best explanation I've seen so far. I was expecting a far less detailed explanation, but I am very pleasantly surprised. It made me realize I don't even need to implement oauth for my API, because it won't even handle user specific data, only global.

[@djrmarketing598]

WOW thank you for the video! This is hands down the best explanation I've ever seen for OAuth2 flows and I've been a programmer for 30 years and it's never made sense on how it works until now.

[@Gabzim]

I’m really glad this was helpful! Thanks for taking the time to leave a comment

[@kiranvarghese672]

[@Gabzim]

I haven’t made it yet, it’s a very simple concept so the video explaining it should be pretty short
