- 6. Agenda ▪ What is OAuth2.0? ▪ OAuth roles from Force.com perspective ▪ Connected apps as a gateway ▪ Authentication flows ▪ Tokens, tokens… tokens everywhere ▪ Step by step flows
- 7. What is OAuth 2.0? (formal) ▪ Is the evolution of OAuth protocol originally created in 2006 ▪ “OAuth2.0 focuses on client developer simplicity while providing specific authorization flows for web, desktop and mobile applications and living room devices” — oauth.net/2 ▪ If feeling brave, check the final version of the spec at: http:// tools.ietf.org/html/rfc6749
- 8. What is OAuth 2.0? (for the common people) ▪ OAuth2 is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service ▪ It works by delegating user authentication to the service that hosts the user account and authorizing 3rd party apps to access the user account ▪ It provides authorization flows for web/desktop apps and mobile devices ▪ The “valet key for the web”
- 9. OAuth roles from Force.com perspective ▪ Resource owner (Salesforce User) ▪ Client (an external app trying to do some cool stuff with Salesforce) ▪ Resource server (the salesforce instance na1.salesforce.com) ▪ Authorization server (the salesforce login hub login.salesforce.com)
- 10. OAuth roles from Force.com perspective
- 11. Connected Apps as a gateway ▪ Previously known a “remote access apps” ▪ Is an application that integrates with Salesforce using APIs such REST and SOAP. ▪ Provides standard OAuth capabilities ▪ Allow administrators to set security policies and have explicit control over who may use the app ▪ Package and deploy friendly (hello ISVs!) ▪ It’s the Salesforce’s abstraction of your external apps
- 12. Connected Apps ▪ When creating, you define OAuth metadata like: ▪ Basic descriptive and contact information for the app ▪ OAuth scopes and callback URL ▪ IP ranges where the app might be running (optional) ▪ Information about mobile policies (optional) ▪ In return you will receive: ▪ A client id (consumer key) ▪ A client secret (consumer secret) ▪ You will need BOTH for almost all authentication flows!
- 13. Connected Apps
- 14. Scopes ▪ API: allows access to the curent logged in user’s account over the Salesforce APIs (includes chatter API) ▪ CHATTER_API: allows acces to Chatter API only ▪ FULL: allows access to all data accessible by current user. Doesn’t include refresh_token ▪ REFRESH_TOKEN: allows to return a refresh token for logged in user. ▪ VISUALFORCE: allows access to Visualforce pages ▪ WEB: allows the ability to use access_token on the Web (includes Visualforce scope)
- 15. A HA moment!
- 16. Callback URL ▪ AKA ‘redirect URI’ ▪ Is an endpoint(*) in your application to which Force.com can redirect the user’s browser with an authentication code or access token ▪ To protect the tokens transactions HTTPS is enforced. HTTP only allowed to localhost ▪ The redirect is a browser redirect
- 17. OAuth flows ▪ Web Server * ▪ User Agent * ▪ JWT (JSON Web Token) ▪ SAML Bearer assertion ▪ SAML assertion ▪ Username and password * ▪ Token refresh * * most used/popular
- 18. Tokens, tokens… tokens everywhere! ▪ Authorization code: short lived token created by the authorization server and passed to the client app via browser. The client app sends the authorization code to the authorization server to obtain an access token or refresh token. ▪ Access token: used by the client app to make authenticated requests on behalf of the end user. Lifetime on the order of minutes/hours, then a new access token must be obtained. ▪ Refresh token: unlimited lifetime or until explicitly revoked by end-user. The client app can store the refresh token to periodically obtain fresh access tokens. MUST PROTECT AS A PASSWORD ▪ ID token: Used and defined by OpenID Connect. Provides information about the logged in user.
