Full Form of OAUTH
What is OAUTH?
OAuth (Open Authorization) is an open standard token-based authentication and authorization protocol that allows users to grant third-party applications limited access to their resources without sharing their credentials. In India, OAuth is widely adopted across digital platforms such as government portals (e.g., DigiLocker, UMANG), banking apps (e.g., UPI-enabled services), and social media integrations (e.g., logging into a service via Google or Facebook). It enables secure delegated access, where an app can request a token from an authorization server to access user data hosted by a resource server. OAuth 2.0 is the current version, used in RESTful APIs and mobile apps. The protocol is crucial for India's Digital Public Infrastructure, ensuring privacy and control over personal data in line with the IT Act and emerging data protection laws. For competitive exams like UPSC, GATE, or NIELIT, understanding OAuth is relevant under computer networks, cybersecurity, and web technologies. It contrasts with SAML (Security Assertion Markup Language) and OpenID Connect, which adds identity layer. OAuth is not just for tech giants; it powers everyday interactions like paying via UPI, accessing e-health records, or signing into educational platforms. Its stateless, token-based nature makes it scalable for India's massive user base.
