This video details how to set up authentication for a project, favoring a simple OAuth (e.g., Google) login for MVPs. The creator discusses using a VPS (Hostinger is sponsored), comparing session storage and JWTs for persistent logins, and the pros/cons of each (sessions simpler, JWTs allow for granular token invalidation). Cookie vs. local storage for token persistence is also covered, emphasizing the importance of preventing XSS vulnerabilities regardless of choice. A GitHub repo with a sample implementation is provided.
