OAuth Vector Logo + PNG

OAuth (short for Open Authorization) is an open standard used for secure access delegation, allowing users to grant websites or applications limited access to their data on other services without sharing passwords.

OAuth is widely adopted across the internet to enable safe authentication and authorization flows between platforms. Major technology companies such as Amazon, Google, Meta, Microsoft, and Twitter use OAuth to let third-party apps access user accounts in a controlled and secure way, making it a core technology behind modern web and mobile integrations.
