# Session High Assurance Policies

Salesforce sessions have a Security Level: Standard or High Assurance. A High Assurance Session Policy forces re-authentication with MFA when a user accesses a flagged object, report, or page. This skill configures the policy and tests it against the sensitive records.

## Recommended Workflow

1. Identify the 1-3 objects/pages that justify High Assurance (scope carefully).
2. Setup → Session Settings → Policies: set the session level for the profile or permission set to 'High Assurance'.
3. For records: use a Login Flow or an Apex service that checks UserInfo.getSessionSecurityLevel() and redirects to MFA if Standard.
4. Write a test: log in from a non-MFA device, navigate to the record, confirm the step-up prompt.
5. Document the UX impact and communicate to the affected user population.

## Key Considerations

- Session security level is per session, not per action; once stepped up the user stays High Assurance until logout.
- Connected apps can be configured with High Assurance requirements separately.
- Mobile SDK apps must support the Refresh Token flow with device PIN to honor High Assurance.
- High Assurance ≠ MFA; it means the session was created with a secondary factor.

## Worked Examples (see `references/examples.md`)

- *Require HA to view SSN field* — HR org.
- *Connected app HA requirement* — Mobile app used by auditors.

## Common Gotchas (see `references/gotchas.md`)

- **Org-wide HA breaks integrations** — API-only integration users fail login.
- **Step-up on report** — Users hit the prompt on every refresh.
- **Mobile SDK crash** — App fails to refresh.

## Top LLM Anti-Patterns (full list in `references/llm-anti-patterns.md`)

- Applying HA org-wide
- Forgetting integration user profiles
- Using HA as a substitute for field-level security
