1. Utilize Secret Chats for End-to-End Encryption:
How it works: Secret Chats employ end-to-end encryption (E2EE), meaning messages are encrypted on your device and decrypted only on the recipient's device. Not even Telegram servers can access the content.
No server storage: Messages aren't stored on Telegram's cloud.
Device-specific: Secret Chats are only accessible on the device where they were initiated.
No forwarding: Messages cannot be forwarded.
Self-destruct timer: You can set a timer for messages to disappear automatically after a set period.
Screenshot alerts (Android): The app brazil telegram phone number list notify you if the recipient takes a screenshot (this feature varies by platform).
How to start a Secret Chat: Open a user's profile and tap "Start Secret Chat".
2. Enable Two-Step Verification (2FA):
How it works: Adds an extra layer of security by requiring a password in addition to the SMS code when logging in on a new device.
Why it's crucial: Prevents unauthorized access to your account even if someone intercepts your SMS code.
How to enable: Go to Settings > Privacy and Security > Two-Step Verification and set a strong password. Consider adding a recovery email address.
3. Review and Adjust Privacy Settings:
Phone Number: Control who can see your phone number (Everyone, My Contacts, Nobody). Consider setting it to "My Contacts" or "Nobody" for greater privacy.
Last Seen & Online: Manage who can see your last seen status (Everyone, My Contacts, Nobody).
Profile Photo: Choose who can view your profile picture (Everyone, My Contacts, Nobody).
Forwarded Messages: Control who can see a link to your account when your messages are forwarded (Everyone, My Contacts, Nobody).
Calls: Decide who can call you (Everyone, My Contacts, Nobody). You can also add exceptions.
Groups & Channels: Limit who can add you to groups and channels (Everyone, My Contacts).
