How is PrivaGuard different from Telegram's built-in local passcode?

Telegram's built-in lock requires an idle timeout (often leaving chats visible for 1 to 60 minutes after you walk away), still leaks incoming message notifications on your desktop screen, and can be bypassed by ending the process. PrivaGuard locks instantly in under 10ms, cloaks notification popups, and captures a silent webcam photo of anyone entering the wrong PIN.

Will I still receive incoming calls or audio rings when Telegram is locked?

Yes. Telegram continues running seamlessly in the background. Audio calls will still ring, but the caller ID and conversation screen remain shielded until you authenticate with your PIN or Master Password.

Does PrivaGuard protect Telegram Portable as well as the Microsoft Store version?

Yes. PrivaGuard targets the Telegram binary process (Telegram.exe) at the Windows kernel level, protecting Telegram Desktop installer, Telegram Portable, and Microsoft Store versions equally.

Can I unlock Telegram with a dedicated password?

Yes. You can configure PrivaGuard to unlock seamlessly with a dedicated per-app password or quick master PIN.

The Vulnerability Gap

Why Telegram's Built-in Lock Leaves You Open

Telegram has a basic passcode feature, but its loose idle timeouts and notification leaks leave critical security gaps on Windows.

Windows Notification Popups New messages arriving on your screen	❌ Leaks Message Text Sender name & message banner display openly	🛡️ Notification Cloaking Suppresses sensitive previews completely
Downloaded Files & Media Photos, documents & voice notes	❌ Open in Cache Readable via Windows File Explorer	🛡️ Process Isolated Telegram UI and cache view locked behind PIN
Intruder Evidence Knowing who attempted to open Telegram	❌ No Record Zero log of failed attempts	🛡️ Silent Selfie Sentry Webcam photo captured via Silent Camera Sentry

Frequently Asked Questions

Common Questions About Locking Telegram Desktop

Everything you need to know about chat privacy, calls, and notification management.

How is PrivaGuard better than Telegram's built-in passcode?

Telegram's native passcode requires waiting for an idle timer (1-60 minutes), still exposes message popups on Windows notifications, and lacks intruder detection (Telegram FAQ Passcode docs). PrivaGuard locks instantly in under 10ms, blocks notification previews, and snaps a silent photo. Review our guide on the top 5 apps you should always lock on Windows.

Will I still receive voice and video calls when Telegram is locked?

Yes. Telegram continues operating in the background. Calls will still ring through your speakers or headphones, but caller details and conversation histories remain shielded behind the frosted lock screen until unlocked.

Does PrivaGuard work with Telegram Portable?

Yes. PrivaGuard hooks the binary process name (Telegram.exe) regardless of whether you installed Telegram from desktop setup, Microsoft Store, or run it as a portable flash-drive executable.

Does PrivaGuard store or read my Telegram messages?

Never. PrivaGuard has zero access to message text or cryptographic keys. It functions strictly as a visual and input barrier at the Windows Desktop Window Manager level, ensuring 100% privacy with zero data collection under our mathematically verified Zero-Telemetry Commitment.

Can I unlock Telegram with my fingerprint?

Yes. You can configure PrivaGuard to unlock seamlessly with custom per-app passwords or master PIN, available across all PrivaGuard commercial tiers.
