Passwords are a friction point. In Day 66, we remove the barrier to entry by implementing Google OAuth2 from scratch. We are building a seamless "Continue with Google" flow that securely authenticates users without them ever typing a password. We go deep into the OAuth2 protocol—not just dropping in a library, but managing the flow ourselves to ensure total control and security. 💡 In this live build: The Backend Router: Implementing oauth.py to handle the handshake with Google's servers. The State Parameter: A critical security feature. We use it to prevent CSRF attacks AND to remember exactly where the user was (e.g., /dashboard) before they clicked login. Account Linking: Smart logic to handle edge cases (e.g., what if a user already has an email account but tries to log in with Google?). The Frontend Handshake: Building a Next.js Callback page that exchanges the code for a JWT and securely signs the user in. By the end, your users can sign up and book a flight in seconds with a single click. 📘 Watch the full playlist: 👉 https://www.youtube.com/playlist?list=PLdtwawCR2QjmdfhM-7SzDOVGop373bbgW 📂 GitHub Repo (Public Mirror): 👉 https://github.com/KNehe/aero_bound_ventures-public.git 🔥 Subscribe to master modern web development. #FastAPI #GoogleOAuth #NextJS #Authentication #WebSecurity #Python #SocialLogin
