Telegram is one of the most popular messaging apps known for its advanced security and privacy features. In this ultimate guide, we’ll dive deep into how to block unwanted contacts, maximize your privacy settings, and protect your communications on Telegram. Whether you’re a new user looking to secure your account or want to become a Telegram security expert, this comprehensive article will provide all the information you need.
Introduction to Telegram Security
Telegram was founded in 2013 by brothers Nikolai and Pavel Durov with the goal of providing a secure and private messaging platform. With over 500 million monthly active users as of 2022, Telegram has become the go-to app for those seeking enhanced communication security.
Some of Telegram’s key security features include:
- End-to-end encryption for secret chats
- Self-destructing messages and media
- Two-step verification
- Ability to block contacts and report spam
- Granular privacy settings for profile, last seen status, calls, etc.
Let’s explore how you can leverage these features to take control of your privacy and security on Telegram.
How to Block Users on Telegram
One of the most basic yet essential security features is knowing how to block in Telegram. Blocking allows you to stop receiving messages, calls, and media from specific users. Here’s how to do it:
- Open the Telegram chat with the user you want to block
- Tap on their profile name at the top
- Select “Block User” from the menu
- Confirm by tapping “Block” in the pop-up
The blocked user will no longer be able to contact you on Telegram. You can view and manage your blocked contacts by going to Settings > Privacy and Security > Blocked Users. From there, you can also unblock users if needed.
Reporting Spam and Abuse
In addition to blocking individual users, Telegram allows you to report spam messages and abusive behavior. When you report a message or user, it helps Telegram identify and take action against malicious actors on the platform.
To report a message:
- Long press on the message
- Tap the “Report” button that appears
- Select the reason for reporting (spam, violence, pornography, etc.)
- Tap “Report” to confirm
Reporting a message will also block the user who sent it. For serious violations, you can go a step further and report the user’s account by opening their profile, tapping the three-dot menu, and selecting “Report.”
Dealing with Harassment and Bullying
Unfortunately, online harassment and bullying can occur on any platform, including Telegram. If you’re experiencing this type of behavior, it’s important to know how to address it effectively.
First and foremost, use the blocking and reporting tools as described above. This will prevent the harasser from contacting you further and alert Telegram to their conduct. Next, document any abusive messages or media by taking screenshots before blocking the user, as this evidence may be helpful if you need to escalate the issue.
If the harassment is severe or persists across multiple accounts, consider reaching out to Telegram’s support team directly. You can email [email protected] with details of the situation and any relevant evidence. Telegram takes user safety seriously and will investigate legitimate reports of abuse.
Remember, you are not alone in dealing with online harassment. Don’t hesitate to seek support from friends, family, or mental health professionals if the experience is causing you distress. There are also online resources and communities dedicated to combating cyberbullying that can provide guidance and solidarity.
Maximizing Privacy Settings
Telegram offers granular privacy settings that let you control who can see your profile information, contact you, and more. To access these settings, go to Settings > Privacy and Security.
Profile Photo and Last Seen Privacy
By default, your profile photo and last seen timestamp are visible to all Telegram users who have your phone number. However, you can restrict this visibility to just your contacts or disable it completely:
- Tap “Profile Photo” or “Last Seen & Online” under the Privacy and Security settings
- Select your preferred visibility option: “Everybody,” “My Contacts,” or “Nobody”
- For Last Seen, you can also choose to share it with “Nobody” but still see other people’s last seen status by selecting the “Nobody (Share my last seen)” option
Phone Number and Forwarded Message Privacy
Similar to your profile photo and last seen status, you can control who is able to see your phone number on Telegram. It’s also important to decide whether you want to allow others to see when a message was forwarded from you:
- Tap “Phone Number” in the privacy settings
- Choose your preferred visibility: “Everybody,” “My Contacts,” or “Nobody”
- Tap “Forwarded Messages”
- Toggle the switch to disable/enable linking your account to forwarded messages
Controlling Who Can Add You to Groups and Channels
Telegram allows users to add you to groups and channels by default. If you prefer to restrict this ability, you can change your settings:
- Go to Settings > Privacy and Security > Groups & Channels
- Select “Who can add me to group chats” or “Who can add me to channels”
- Choose from “Everybody,” “My Contacts,” or “Nobody”
Note that if you select “Nobody,” you will need to manually approve any group or channel invitations before joining.
Adjusting Calls and Peer-to-Peer Settings
Telegram offers both Voice over IP (VoIP) and peer-to-peer (P2P) communication for calls and file sharing. You can customize these settings to your comfort level:
For calls:
- Go to Settings > Privacy and Security > Calls
- Choose who can call you: “Everybody,” “My Contacts,” or “Nobody”
- Toggle “Peer-to-Peer” to use direct connections for calls when possible
For P2P file sharing:
- Go to Settings > Privacy and Security > Peer-to-Peer
- Toggle “Use P2P” to enable/disable P2P connections for file sharing and call traffic
Disabling P2P will route all your calls and shared files through Telegram’s servers, providing an extra layer of obfuscation at the cost of potentially slower transfers.
Passcode Lock
For added security, you can enable a passcode lock for your Telegram app. This ensures that even if someone gains access to your unlocked phone, they won’t be able to open your Telegram chats without the passcode.
To set up a passcode lock:
- Go to Settings > Privacy and Security > Passcode Lock
- Toggle the passcode lock feature on
- Enter your desired passcode and passcode hint
- Choose the auto-lock time (immediately, after 1 minute, 5 minutes, or 1 hour)
You can also enable an additional layer of protection by requiring your passcode for every Telegram login attempt.
Secret Chats and Self-Destructing Content
One of Telegram’s most powerful security features is secret chats. Unlike regular chats, secret chats use end-to-end encryption, leave no trace on Telegram’s servers, and allow you to send messages with self-destruct timers.
Starting a Secret Chat
To initiate a secret chat:
- Tap the new message icon in your chat list
- Select “New Secret Chat”
- Choose the contact you want to start the secret chat with
- Once the chat is created, you’ll see a lock icon indicating it’s a secret chat
Note that secret chats are device-specific. If you start a secret chat on your phone, you won’t be able to access it on your computer or tablet.
Self-Destructing Messages and Media
Within a secret chat, you have the option to send messages and media that automatically self-destruct after a set time period. This ensures that sensitive information doesn’t linger on the recipient’s device.
To send a self-destructing message:
- In the secret chat, tap the clock icon in the message input field
- Set the desired self-destruct timer (from 1 second to 1 week)
- Compose your message and tap send
The timer starts as soon as the recipient opens the message. Once the time runs out, the message disappears from both devices.
Secure Calling
Telegram also offers secure voice and video calls. Calls are end-to-end encrypted and use peer-to-peer technology to avoid routing through Telegram servers whenever possible. This enhances privacy and reduces potential interception points.
To make a secure call, simply tap the phone or video icon in any Telegram chat, including secret chats. You can verify the security of the call by comparing emojis shown on both users’ screens – if they match, your call is 100% secure. <h2>Two-Step Verification</h2>
Two-step verification adds an extra layer of security to your Telegram account by requiring a password in addition to the login code sent via SMS. This helps protect your account even if your phone number is compromised.
To enable two-step verification:
- Go to Settings > Privacy and Security > Two-Step Verification
- Tap “Set Additional Password”
- Enter a strong password and a password hint
- Provide a recovery email address in case you forget your password
- Confirm the password and email again
With two-step verification enabled, you’ll be prompted for your password each time you log in to Telegram on a new device.
Using a Password Manager for Secure Credentials
Creating and remembering strong, unique passwords for all your accounts can be a challenge. That’s where password managers come in handy. These tools securely store your login information and can generate complex passwords for you.
When setting up two-step verification on Telegram, consider using a password manager to create and store your password. Some popular options include LastPass, 1Password, and Dashlane. Many password managers also offer browser extensions and mobile apps for convenient access to your credentials.
Using a password manager not only enhances your Telegram security but also promotes good password hygiene across all your online accounts. Just remember to use a strong master password for the password manager itself and enable two-factor authentication when available.
Securing Your Device
While Telegram provides robust security features, it’s equally important to secure the device you use to access the app. Some best practices include:
- Setting a strong device passcode or biometric lock
- Keeping your device’s operating system and apps updated
- Installing reputable anti-malware software
- Avoiding suspicious links and downloads, even within Telegram chats
- Periodically reviewing and revoking Telegram sessions on unused devices
Enabling Disappearing Messages
In addition to secret chats, Telegram recently introduced disappearing messages for regular chats and groups. When enabled, messages will automatically delete after a set time period for all participants.
To enable disappearing messages:
- Open the chat or group where you want to enable the feature
- Tap the chat name at the top
- Select “Disappearing Messages”
- Choose a timeframe (24 hours, 7 days, or a custom duration)
Once enabled, any messages sent in the chat will disappear after the specified time. This feature is useful for chats where you want to keep the conversation ephemeral or reduce clutter. However, remember that participants can still take screenshots or save content before it disappears, so exercise caution when sharing sensitive information.
Beware of Social Engineering and Phishing Attacks
Even with strong technical security measures in place, users can still fall victim to social engineering and phishing attacks. These attacks aim to trick you into revealing sensitive information or taking actions that compromise your security.
Some common tactics to watch out for on Telegram include:
- Messages claiming to be from Telegram support asking for your login credentials or personal information
- Links that appear to be from legitimate sources but actually lead to malicious websites
- Requests to forward messages or join groups from unknown users
- Offers that seem too good to be true, such as promises of free cryptocurrency or exclusive investment opportunities
To protect yourself from these threats:
- Never share your Telegram login credentials with anyone, including users claiming to be from Telegram support
- Be cautious when clicking on links, especially from unknown sources. Verify the URL before entering any information.
- Don’t forward messages or join groups from untrusted users
- If an offer seems suspicious or too good to be true, it probably is. Trust your instincts and err on the side of caution.
If you suspect you’ve fallen victim to a phishing attack or your account has been compromised, contact Telegram support immediately and change your account password. Reporting suspicious messages and users can also help protect the wider Telegram community.

Can I use Telegram on multiple devices?
Yes, Telegram allows you to use your account on multiple devices simultaneously. You can log in to Telegram on your phone, tablet, and computer, and all your chats and media will sync seamlessly across devices. However, keep in mind that secret chats are device-specific and cannot be accessed on multiple devices. To use Telegram on a new device, simply download the app and log in with your phone number. You’ll receive a login code via SMS or Telegram message, which you’ll need to enter to authenticate your account. Make sure to review your active sessions regularly and terminate any unused or unrecognized sessions for added security.
How can I verify the security of a Telegram voice or video call?
Telegram’s voice and video calls are end-to-end encrypted, ensuring that only you and the person you’re communicating with can access the call’s content. To verify the security of a call, both participants will see the same set of four emoji on their screens. If the emoji match, you can be confident that your call is secure and no one else is listening in. This emoji-based verification system provides a user-friendly way to confirm the integrity of your calls without needing to compare long, complex security codes. Always make sure to check the emoji before discussing sensitive information during a Telegram call.
What is the difference between disappearing messages and self-destructing media?
Disappearing messages and self-destructing media are both features that allow you to send temporary content on Telegram, but they work in slightly different ways. Disappearing messages are enabled for an entire chat or group, and any messages sent after enabling the feature will automatically delete for all participants after a set time period (24 hours, 7 days, or a custom duration). Self-destructing media, on the other hand, is a feature within secret chats that allows you to send individual messages or media files that disappear after a specified time (from 1 second to 1 week) once the recipient has opened them. Both features are useful for sending ephemeral content and maintaining privacy.
How do I create a Telegram group or channel?
To create a Telegram group, tap the new message icon in your chat list and select “New Group.” Choose the contacts you want to add to the group, enter a group name, and tap the checkmark to create the group. Groups can have up to 200,000 members and are ideal for collaboration and discussion among a larger audience. To create a channel, tap the new message icon and select “New Channel.” Choose a name and description for your channel, set it as public or private, and invite users to join. Channels are suited for broadcasting messages to an unlimited number of subscribers and can be useful for news, updates, or content distribution.
Can I delete messages I’ve already sent on Telegram?
Yes, Telegram allows you to delete messages you’ve already sent, both for yourself and for the recipient(s). To delete a message, long press on the message and tap the trash can icon. You’ll be given the option to “Delete for me” or “Delete for everyone.” Choosing “Delete for everyone” will remove the message from the chat for all participants, as long as the message was sent within the last 48 hours. Keep in mind that deleted messages will be replaced with a notification stating that the message was removed, and the recipient(s) will still know that a message was deleted.
What is the purpose of Telegram’s self-destructing photos and videos?
Telegram’s self-destructing photos and videos, also known as self-destructing media, provide a way to share sensitive or temporary visual content that automatically disappears after the recipient has opened it. This feature is available within secret chats and allows you to set a timer for the media to self-destruct, ranging from 1 second to 1 week. Self-destructing media is useful when you want to share a photo or video that you don’t want to remain on the recipient’s device indefinitely, such as personal images, confidential documents, or time-sensitive information. Once the recipient opens the media, the timer starts, and the photo or video will disappear from both devices after the set time has elapsed.
How can I prevent someone from adding me to Telegram groups or channels?
To control who can add you to Telegram groups or channels, go to Settings > Privacy and Security > Groups & Channels. Under “Who can add me to group chats” and “Who can add me to channels,” you can choose from three options: “Everybody,” “My Contacts,” or “Nobody.” Selecting “My Contacts” will only allow users in your contact list to add you to groups or channels, while choosing “Nobody” will prevent anyone from adding you without your explicit approval. If you choose “Nobody,” you will need to manually approve any group or channel invitations before joining. Adjusting these settings gives you greater control over your Telegram experience and helps avoid unwanted group or channel memberships.
Does Telegram offer end-to-end encryption for all chats?
While Telegram provides end-to-end encryption for secret chats, not all chats on the platform are end-to-end encrypted by default. Regular one-on-one chats and group chats use client-server encryption, which means that messages are encrypted between the user’s device and Telegram’s servers, but Telegram retains the ability to access the messages if needed. However, Telegram states that they do not access or store user data unless required by law. To ensure end-to-end encryption, where only the communicating parties can read the messages, users must initiate a secret chat. Secret chats offer an additional layer of security and privacy, as they are not stored on Telegram’s servers and support self-destructing messages.
Conclusion
By following the steps outlined in this guide, you can significantly enhance your security and privacy on Telegram. From blocking unwanted users and maximizing privacy settings to leveraging secret chats and two-step verification, Telegram offers a comprehensive suite of tools to protect your communications.
Remember, security is an ongoing process. Regularly review your settings, educate yourself on emerging threats, and encourage your contacts to adopt secure messaging practices as well. With diligence and the right tools, you can enjoy the benefits of Telegram while minimizing the risks.
