The login screen flickers. You’ve got a user on the edge of access, and the data at stake isn’t just valuable—it’s personal. PII sits in your system waiting to be read, copied, stolen. This is where PII Catalog Step-Up Authentication takes control.
Step-up authentication adds stronger identity checks only when the stakes are high. Applied to a PII catalog, it means guarding sensitive fields with a second layer of proof. A password might get a user into the app, but accessing social security numbers, medical data, or bank details triggers an extra challenge: a verified device, a TOTP code, a WebAuthn passkey. It’s precise security without smothering every interaction.
Implementing PII Catalog Step-Up Authentication starts with mapping your data catalog. Identify each PII field and tag it with sensitivity levels. Integrate with your identity provider to trigger second-factor prompts when a user request hits those tags. This can be done through policy-based access control, API middleware, or conditional checks in service code. Logging and auditing are not optional—track who passed step-up, when, and from where.
