OIDC Login Forms

An open standard for authorization; anyone can implement it Provides “secure delegated access” to client applications Works over HTTPS and authorizes: Devices APIs Servers Applications … with access tokens rather than credentials What is OAuth?

OAuth 2.0 Enables apps to obtain limited access (scopes) to a user’s data without giving away a user’s password Decouples authentication from authorization Supports multiple use cases addressing different client capabilities and deployment models Server-to-server apps Browser-based apps Mobile/Native apps Consoles/TVs Web-scale delegated authorization framework for REST/APIs Protecting APIs Since October 2012
