OAuth2

Use OAuth2 to safely authorize access to your data

ownCloud uses OAuth, the open industry-standard protocol for secure authorization of clients. It greatly enhances security while facilitating the integration of third-party apps or web services. It connects the ownCloud Clients (Desktop, Android, iOS) 

Its standardized and secure authorization flow means that users don’t ever have to enter or store their credentials in the Desktop and Mobile Apps. Rather, there are access tokens specific to the clients used so that user sessions can selectively be revoked. This also provides a user authorization interface for developers to stwiftly integrate ownCloud into their applications.
