OAuth
OAuth is a security system that lets users log into websites or apps using their accounts from other services (like logging into a new app using your Google or Facebook account). It's like a digital key card system - instead of creating new username and password combinations for every service, users can safely use their existing accounts. When recruiters see OAuth in job descriptions or resumes, it means the candidate has experience with implementing secure login systems and handling user authentication safely.
