Security & App Lock

App Lock

App Lock protects your Zentro session with a PIN when you're away from your workstation. After a configurable idle timeout, the app locks automatically and requires the PIN to resume.

Setting Up App Lock

1. Go to Settings → Security → App Lock
2. Enable App Lock
3. Set a PIN (any non-empty value — there's no minimum length requirement)
4. Configure the idle timeout — a preset of 1, 5, 15, or 30 minutes (default: 5 minutes)

Locked State

When the app locks, all content is hidden behind a PIN entry screen. Open connections and editor state are preserved — entering the correct PIN resumes exactly where you left off.

Windows Fallback After Repeated Failures

After 3 incorrect PIN attempts, the lock screen offers a "Verify with Windows" option that unlocks the app using your current Windows account instead of the PIN.

PII Detection & Column Blur

Zentro scans result columns for personally identifiable information. Detection runs automatically; blurring itself is opt-in — turn on Blur sensitive columns in the result panel toolbar to have detected columns rendered with a frosted blur effect in the grid.

Detected Patterns

How It Works

When a query result loads, Zentro runs pattern detection on the values in each column. Columns where a significant portion of values match a PII pattern are automatically blurred — cell contents get a CSS blur filter applied in the grid (the underlying text isn't masked or replaced, just visually obscured, and can't be selected while blurred).

Manual Overrides

• Blur a column: right-click column header → Blur column
• Unblur a column: right-click column header → Unblur Column
• Toggle all blurred columns: use the blur icon in the result panel toolbar
