More in LearnWhat Are oAuth and oAuth2?
OAuth (Open Authorization) is an open standard protocol that allows third-party applications to access user resources from a web service without exposing the user’s password.
It works by providing access tokens that authorize limited permissions, letting users grant access to their data (e.g., Google contacts, Twitter posts) without sharing their credentials.
OAuth 2.0 is the updated version, widely adopted due to its enhanced security and simplicity. OAuth2 introduces new flows for obtaining access tokens, offers more flexible authorization options (like explicit scopes for limiting permissions), and supports a broader range of devices and use cases, making it the preferred standard for modern web and mobile applications.
