What this session would cover

Proposed outline — the mentor finalises the agenda once this topic is scheduled.

  1. 1Why application identity & access matters — the common problem: Users can see other customers' data because authorization checks are missing or inconsistent.
  2. 2Core concepts in plain language: Authentication versus authorization, sessions, tokens, OAuth, OpenID Connect, single sign-on
  3. 3Going further: multifactor authentication, passkeys, role-based access control, attribute-based access control, tenant boundaries, account recovery
  4. 4Framework walkthrough: OpenAPI Contracts, Twelve-Factor App, OAuth 2.0 / OpenID Connect
  5. 5Practical workflow, built live: Login with sessions or tokens, RBAC checks, tenant isolation tests and a recovery flow.
  6. 6How to measure it: Error rate, p95 latency, Contract-test pass rate, Duplicate-processing incidents
  7. 7An illustrative case (a fictional example, not a client result), then live Q&A on your own situation
