To enhance security, Telegram offers a built-in Passcode Lock feature. A user can set a four-digit passcode and optionally enable fingerprint unlock for more convenience. By adjusting the auto-lock timer to one minute, the app provides better privacy, ensuring no unauthorized person can access the chats.
Privacy settings allow control over who can see a phone number on Telegram. Options include making the number visible to everyone, only contacts, or no one at all. Exceptions can be added for specific individuals to either always allow or never allow them to see the number, providing granular control.
Enabling Two-Step Verification introduces an extra layer of security beyond simple SMS codes. This process requires creating a unique password, a hint for recovery, and setting up a recovery email. Once active, the account becomes nearly impossible for hackers to breach, as both SMS and the custom password are needed for login.
Online status and last-seen activity can be restricted to specific groups or blocked entirely. Similarly, profile photos and videos can be hidden from the general public or specific contacts. Users can manage these settings from the Privacy and Security section, ensuring their digital presence is only visible to their inner circle.
Telegram prevents unsolicited calls and random group additions through dedicated privacy toggles. The settings can be adjusted so only trusted contacts can initiate calls or add the user to various groups and channels. This helps in avoiding spam and keeping the messaging experience focused on personal and work-related interactions.
To save mobile data and prevent device storage from filling up, automatic media downloads can be disabled. By turning off auto-download for photos and videos across mobile data and Wi-Fi, media is only saved when manually initiated. This simple adjustment ensures the phone runs smoothly without getting clogged by unnecessary files.
The app provides a central location to view, add, or remove blocked users, giving full control over unwanted interactions. Additionally, users can restrict others from linking to their account when forwarding their messages. This ensures that even if a message is shared, the original sender's profile remains private and not directly accessible.
