Why OAuth?

Open: A standard protocol that enables secure API access

Simple: No need to write UI or handle SSO/2-Factor/etc.

Mobile: Mobile Policies, No API Tokens, IP Bypass, etc.

Secure: Gets rid of passwords in Apps. Strong crypto options

Page 4: Authentication with OAuth and Connected Apps

The World’s Simplest

OAuth Client

Page 5: Authentication with OAuth and Connected Apps

Step 1: Register your App

Page 7: Authentication with OAuth and Connected Apps

Step 3: Exchange the Code

curl -d

'grant_type=authorization_code&client_id=CLIENT_ID&clie

nt_secret=CLIENT_SECRET&redirect_uri=YOUR_URL_E

NCODED_REDIRECT_URI&authorization_code=CODE'

https://login.salesforce.com/services/oauth2/token

Page 8: Authentication with OAuth and Connected Apps

Step 4: You’re Done - Use your token!

GET /resource HTTP/1.1

Host: na1.salesforce.com

Authorization: Bearer czZCaGRSa3F0MzpnWDFmQm….

curl -L -H 'Authorization: Bearer ACCESS_TOKEN' -H "X-

PrettyPrint: true" RESOURCE

Let’s Build a Web App

Page 10: Authentication with OAuth and Connected Apps

Code Flow: How does it work?

1) App Redirects User to

Authorization Services where

User is Authenticated and

Authorizes App

2) Code Returned to App

3) App Exchanges Code at Token

Service

Page 13: Authentication with OAuth and Connected Apps

Token Flow How does it work?

1) App Redirects User to

Authorization Services where

User is Authenticated and

Authorizes App

2) Token Response returned

directly to app on URL behind a

# fragment

Page 14: Authentication with OAuth and Connected Apps

What happens on Mobile?

1) Device opens a browser with

authorization URL

1) Tokens returned on URL behind

# fragment – instrumented

browser is monitoring and

parses URL

What the User Sees:

Authentication Authorization

Page 16: Authentication with OAuth and Connected Apps

Codified Best Practice: Mobile SDK & Container

NATIVE HYBRID WEB

OAuth2.0 Standard authentication

implementation providing single

sign-on for trusted apps

Secure Storage Securely store credentials and

business sensitive data with

enterprise-class reliability and

security

Mobile Login User experience, processes and

policy control optimized for the

mobile environment

Page 19: Authentication with OAuth and Connected Apps

Notice SSO works! Refresh Tokens

It’s a lot like a password

Allows you to get more sessions

Make sure you treat it like one!

POST /services/oauth2/token HTTP/1.1

Host: login.salesforce.com

Content-Type: application/x-www-form-urlencoded

grant_type=refresh_token

&refresh_token=5Aep8615VRsd_GrUz3LAcJl

&client_id=MyApp

&redirect_uri=myapp%3A%2F%2Fcallback

Let’s Build an Integration App

Page 21: Authentication with OAuth and Connected Apps

What if I just want to call server to server

Uid / Password Flow

- Simple, but uses passwords, API tokens, etc.

Web SSO Assertion Flow

- Reuse SAML SSO and existing Trust

SAML/JWT Assertion Flow

- Cert and Trust Specific to the App

Enterprise Class Authorization

with Connected Apps

Page 24: Authentication with OAuth and Connected Apps

Admin Authorization for OAuth Apps

1) Admin “installs” app

2) App Uses any OAuth Flow

3) User Authorization is evaluated

via Admin settings

Page 25: Authentication with OAuth and Connected Apps

Final Thoughts

No one likes plumbing….use a toolkit

Make your login URLs configurable

login.salesforce.com, test.salesforce.com, other

Protect against attacks

Set a cookie, and check for it on response
