@H Sharma well, he explained it to a room full of software developers, who, I assume, already have some experience in Web development, not to a room full of nursery kids.

I skipped this video before cause it long, came back through a reddit post and 18 mins into it. I understood the fundamentals

I just explicitly logged into youtube to like this video. Thanks so much for putting this talk together and demystifying this stuff.

[@brittlindgren1443]

Things that I really appreciated about this video 1. Introduced workflow without any or with minimal technical terms 2. Introduced the terminology and explained in simple terms 3. Went back to the workflow and incorporated the terminology with the workflow 4. Repeated questions from the audience so that those of us watching the video knew what the question was What a great video!!! Nate did a great job of teaching this material!

Imagine this bright guy explaining this stuff to a room of immature 19 year olds. Not just once, but year, after year, after year. Its like keeping a killer whale in a basin, he ll die from boredom. Theres an old saying that goes; those who can, do, those who cant, teach. he can.

I am so thankful I stumbled on this video. I felt horrible for not being able to wrap my head around this stuff easily. Thank you for this video! It was super helpful.

[@nbarbettini]

Don't feel bad, everyone finds this stuff complex! The reason I wrote this talk initially was because I was confused myself.

[@officialdanieldsouza]

Thanks again! The way you explained this stuff was really easy to grasp. Would you be able to do one on JWT?

[@ivangutowski-smith5590]

now THIS: is how you do a presentation, clear, and build up the presented information as you teach it. The one thing that is so small, but a sign of a fantastic presenter: 26:30 a guy asked a question, Nate repeated it back to summaries he understood it welll - and for us watching a recording - we could hear the question... So professional, impeccable presentation and clear content.

[@nbarbettini]

This was much longer than the other videos I've watched on OAuth 2.0, but this one was a much better explanation. Worth the extra time.

I was scratching my head when I used to hear the word OAuth. Now I clearly understood the OAuth basics. Thanks for explaining with this much of clarity.

[@djzenma]

I usually never comment, but this was an amazing talk. He not only explained how the protocols work, but also their history, the bad solutions that the companies tried before these protocols were created, and how OAuth and OIDC solved these problems and standardized authentication and authorization in the web. Love it!

[@OktaDev]

Thanks for leaving this comment. It means a lot. We hope to see you around in our other content :)

I just watched half of it and can't stop myself commenting. I knew Oauth before but I always have a missing piece in the puzzle. I had to unlearn to relearn in the perfect way. Awesome presentation and explanation. you got a skill !! Glad I found this video

Only six minutes in, and it's obvious you're a great teacher! You're acknowledging the problem: the jargon and terminology. Explaining why it's a problem: how are you supposed to learn something new when someone uses language you don't understand? And giving examples of the frustration: newbies bounce from one stackoverflow post to the next, each saying the other person is wrong. (That's me, btw!) Looking forward to the whole talk! Thanks so much for posting!
