1. Chat Privacy

Secret Chats: End-to-End Encryption (E2EE)

Telegram’s Secret Chats provide military-grade security for sensitive conversations:

  • Activation:
    1. Open a chat > Tap profile name > Start Secret Chat.
    2. Verify encryption via Key Visualization (compare emojis with the recipient).
  • Features:
    • Device-Specific: Only accessible on the initiating device.
    • No Cloud Backups: Messages aren’t stored on Telegram’s servers.
    • Forward Lock: Prevents message sharing outside the chat.
Feature Secret Chats Regular Chats
Encryption E2EE (MTProto 2.0) Client-server encryption
Cloud Storage Disabled Enabled by default
Self-Destruct Yes (timer-based) Manual deletion only

2025 Update: Secret Chats now support multi-device syncing for Premium users.

Self-Destruct Timers

Automatically erase messages after a set period:

  1. In a Secret Chat, tap Timer (⏳) > Choose duration (1s – 1w).
  2. Timer applies retroactively to existing messages.

Limitations:

  • Recipients can screenshot messages before deletion.
  • Timers don’t apply to forwarded content.

Forward Protection

  • Disable Forwarding:
    • Secret Chats: Built-in block on message sharing.
    • Regular Chats: Use Restrict Saving Content (channel setting) to limit media downloads.

2. Group Security

Group Privacy Settings

Control visibility and access:

  • Public Groups: Searchable via Telegram; indexed by Google/Bing.
  • Private Groups: Invite-only via links (revocable) or admin approvals.

Adjust:

  1. Group > Edit > Group Type > Toggle Public/Private.

Admin Rights & Moderation

Assign granular permissions to moderators:

  • Key Permissions:
    • Ban Users: Block disruptive members.
    • Delete Messages: Remove spam or harmful content.
    • Pin Messages: Highlight announcements.

Steps:

  1. Group > Members > Select user > Promote to Admin.
  2. Customize permissions under Admin Privileges.

Auto-Moderation:

  • Use bots like Safeguard to filter keywords (e.g., slurs, phishing links).

Join Restrictions & Member Privacy

  • Invite Links: Generate links with usage limits (expiry date, max joins).
  • Member Approval: Enable Request to Join for private groups.
  • Hide Members List:
    1. Group > Edit > Permissions > Toggle Hide Members.

Risk: Public groups expose member profiles to scrapers.

3. Channel Management

Channel Visibility & Subscriber Privacy

  • Public Channels: Appear in search results; customizable vanity URLs.
  • Private Channels: Hidden; access via invite links.

Subscriber Privacy:

  • Hide Subscribers: Enable under Channel Settings > Permissions.
  • Restrict Analytics: Premium channels (>10k subs) can anonymize viewer metrics.

Post Restrictions & Anti-Leak Tools

  • Disable Media Saving:
    1. Channel > Edit > Restrict Saving Content > Enable.
  • Watermarking: Add custom logos to images/videos to deter unauthorized sharing.

2025 Feature: AI-driven Content ID scans for copyrighted material.

Comment Settings

Link channels to discussion groups for moderated interactions:

  1. Channel > Edit > Discussion > Link existing group.
  2. Manage comments via Delete or Ban buttons.

Monetization: Use bots like InviteMember to gate comments behind paywalls.

Pro Tips for 2025

  1. Layer Protections: Combine Secret Chats with VPNs (e.g., NordVPN) to mask IPs.
  2. Audit Monthly: Review active sessions (Settings > Devices) and third-party app access.
  3. Avoid Cloud Backups: Disable Chat Backup for sensitive conversations.
  4. Use Burner Numbers: Sign up with virtual numbers (e.g., Google Voice) to anonymize accounts.

By mastering these tools, users can leverage Telegram’s social power while minimizing exposure. For activists and journalists, combining Secret Chats with Self-Destruct Timers ensures critical communications remain confidential.

Final Note: Telegram’s 2025 updates prioritize transparency with third-party verification (✅) but retain metadata risks. Stay vigilant—features like E2EE Video Calls and Encrypted Group Chats remain absent, making Signal a better choice for high-risk users. Regularly consult Telegram’s Privacy Hub for policy shifts.
