Why do some items ask me for biometric or extra verification again?

High-sensitivity items (S3 and S4) require **step-up authentication**, a fresh biometric or TOTP check, before they can be viewed, even if you're already signed in. This protects the most critical secrets from being accessed if you leave your session unattended.

You can see and adjust an item's sensitivity by opening it and choosing **Security → Sensitivity level**.
