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 (minimum 4 digits)
4. Configure the idle timeout (default: 5 minutes; range: 30 seconds to 1 hour)

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.

OS Credential Fallback

After 3 incorrect PIN attempts, Zentro offers a fallback: verify your Windows user account password to unlock the app.

PII Detection & Column Blur

Zentro automatically scans result columns for personally identifiable information and blurs them in the data 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 values are replaced with •••••• in the grid.

📸 Screenshot needed: Data grid with PII columns blurred (e.g. an email and phone column showing ••••••). The blur toggle button in the result panel toolbar should be visible.

Manual Overrides

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

Secret Vault

The Secret Vault stores named credentials in an encrypted local store backed by the OS keychain.

Use the Vault when you want to:

• Keep a credential accessible across multiple connection profiles without re-entering it
• Separate secret storage from connection configuration

Configure in Settings → Security → Vault.
