This is one of the clearest breakdowns of OAuth 2.0 I've come across especially the step-by-step flow with Zomato and Google. Really helpful for beginners trying to visualize how secure delegation works in real apps. As someone learning DevOps and web fundamentals, I’ve found that understanding the roles and token exchange is key to integrating OAuth securely. The comparison between Authorization Code vs Access Token is gold it clears up so much confusion. If you're diving into backend or API security, this post is a must-read. I’m exploring these concepts in Bangla too, so feel free to connect if you're interested in localized tech learning or want to discuss OAuth flows in real-world projects. 🚀
