Issues
§ Authentication per Mobile App.
§ No invalidation of access token
§ No clean up of offline/cached data on device

45. Deployment Models
• Enterprise in-house native apps
• Native App for a SaaS provider
• Multiple native apps for a single SaaS provider

46. NAPPS
• OIDF working group
• Profile of OpenIDConnect
• Participants include (VMware, AirWatch, Ping
Identity, Mobile Iron, Okta, OneLogin…)

47. NAPPS Terminology
• Token Agent: Native app that obtains access tokens on behalf of
other native apps
• AppInfo Endpoint: Endpoint to obtain metadata about apps
• Primary Token: OAuth token obtained by TA for its own use
• Secondary Token: OAuth token obtained by TA on behalf of other
native app
