Evidence boundary: Existing applications remain unchanged by this default-setting event unless they are separately reconfigured.
What changes
Auth0 changes the creation-time default for affected third-party applications from the previous permissive baseline to strict security mode.
Who is affected
- Teams creating new third-party applications after the effective date.
- Provisioning automation that assumes the earlier default behaviour.
- Integration tests that rely on permissive settings unless explicitly configured.
Timeline
The new default applies from 23 October 2026.
Required action
- Review application-creation workflows and templates.
- Make required security settings explicit rather than relying on defaults.
- Test onboarding and authorization flows under strict mode.
What is not affected
The change does not automatically alter existing third-party applications.
PlatformTrace analysis
This is a default-policy change rather than a service retirement, but it can create deployment regressions where automation silently depended on the old baseline.
