Why Signal Is Better Than Telegram for Security

If you’re on the hunt for a secure messaging app, you've probably come across both Signal and Telegram. While both are popular choices, I’ve been using Signal for years, and from my experience, Signal is hands-down better than Telegram for security. In this article, I’ll walk you through why that is, highlight Signal’s key privacy features, and share some practical tips to get the most out of it.

Understanding the Security Difference Between Signal and Telegram

Before diving into the nitty-gritty, it helps to understand the core security differences between Signal and Telegram. The main draw of Signal’s security is that it uses end-to-end encryption by default for all messages and calls—meaning only you and the person you're communicating with can read or listen, not even Signal themselves.

Telegram, on the other hand, only offers end-to-end encryption in its “Secret Chats.” Regular chats on Telegram are encrypted in transit but stored on their servers, which technically means they could be accessed (or potentially leaked) if the servers were compromised.

So, if you’re serious about security, this default end-to-end encryption makes Signal a safer choice right out of the gate.

Why Signal’s Security Features Are a Cut Above

Using Signal daily has shown me several subtle but important security advantages it holds over Telegram. Here’s what sets it apart:

• Default End-to-End Encryption Everywhere: Every message, voice call, video call, group chat, and even status updates on Signal are encrypted by default. No need to switch modes or start a “secret” chat manually.
• Open Source and Peer-Reviewed: Signal’s code is open source and regularly reviewed by security experts. Telegram’s server-side code is proprietary, which means you’re trusting their claims without the same level of transparency.
• Minimal Data Collection: Signal collects almost no user metadata—just your phone number. No profile pictures, no contact lists, no message history stored on servers.
• Disappearing Messages and Screen Security: Signal lets you set messages to disappear after a custom time and also prevents screenshots in chats if you enable “Screen Security.” This is a neat layer of privacy Telegram lacks in its default chats.
• Registration Lock: Signal supports a registration lock PIN, which adds a layer of protection against SIM swapping—something I recommend enabling immediately after installing.

Step-by-Step: Enabling Signal’s Security Settings

If you’re new to Signal or want to tighten your security, here’s how to enable some of these key features:

1. Enable Registration Lock PIN:
   • Open Signal, tap your profile icon.
   • Select Privacy, then tap Registration Lock.
   • Turn on Registration Lock and set a PIN you’ll remember.
2. Turn on Disappearing Messages:
   • Open any chat, tap the contact name at the top.
   • Select Disappearing Messages.
   • Choose a timer (from 5 seconds to 1 week) for messages to self-destruct.
3. Enable Screen Security:
   • Go to your profile icon > Privacy.
   • Toggle Screen Security on to prevent screenshots and screen recording.

These settings add meaningful layers of privacy that you won’t find by default on Telegram chats.

Practical Tips From a Daily Signal User

After using Signal almost exclusively for messaging, I’ve picked up some handy tips that aren’t immediately obvious but make a big difference:

• Verify Safety Numbers: Every contact has a safety number—a cryptographic fingerprint. It’s worth verifying these with close contacts by scanning QR codes or comparing numbers. This ensures you’re not being MITMed (man-in-the-middled).
• Use Signal Desktop Mindfully: The desktop app syncs messages securely but only when your phone is online. I keep my phone on, but if you close Signal on your phone, desktop messages stop syncing—something to keep in mind.
• Backup Wisely: Signal doesn’t store message history on servers, and backup options are device-specific and encrypted. On Android, you can create encrypted backups locally, but on iOS, messages are stored in encrypted iCloud backups if you use them. Always use a strong device passcode!
• Group Chats Stay Private: Unlike Telegram, Signal groups also use end-to-end encryption. Plus, group membership changes require admin approval, adding a helpful layer to avoid random intruders.
• Double-Check Your Contacts: Signal syncs your contacts but doesn’t upload them to servers in plain text. However, it’s smart to review who you’re chatting with regularly and remove contacts you no longer trust.

Minor Quirks and Workarounds Worth Knowing

Signal isn’t perfect—like any app, it has quirks. For example:

• Sometimes Delayed Delivery: Signal messages rely on push notifications, which occasionally get delayed if your phone’s app is restricted in the background. Make sure Signal is allowed to run freely in your phone’s battery optimization settings.
• Contact Sync Needs a Bit of Patience: Signal doesn't show you if a contact is on Signal immediately. It may take a moment to refresh the contact list, so don’t worry if you don’t see the Signal icon right away.
• Limited Stickers and Customization: Signal keeps stickers and customization minimal for security reasons. If you love flashy features, Telegram might feel more fun, but I prefer Signal’s no-nonsense approach for privacy.

Conclusion: Making the Switch to Signal for Real Security

So, why is Signal better than Telegram for security? Because Signal’s default end-to-end encryption, minimal data collection, open-source transparency, and robust privacy features all add up to a safer messaging experience. While Telegram is slick and feature-rich, it simply can’t match Signal’s commitment to privacy at the foundational level.
