Many users wonder what a secret Telegram chat is , how to create one, and what the real differences are compared to other apps like WhatsApp. In a digital world where privacy is increasingly valued, understanding these tools is essential. If you have any questions about this type of communication, this article will answer all your queries in detail.
How Telegram works and its data architecture
Since its launch, Telegram has established itself as a powerful alternative thanks to its multiplatform nature . Unlike other services, Telegram uses a cloud-based infrastructure , allowing users to access their account from multiple devices (mobile, tablet, computer) simultaneously and with instant synchronization of all chats and files.
To understand the difference with WhatsApp, it's vital to analyze storage. While WhatsApp primarily acts as a distribution center and doesn't store messages on its servers once delivered, Telegram stores a copy of regular chats on its encrypted servers. This is what allows you to keep your conversations if you change phones and avoid relying on external backups to Google Drive or iCloud, even making it easy to import WhatsApp chats to Telegram.
Regarding encryption, WhatsApp uses end -to-end encryption by default, meaning that only the participants have the key to decrypt the message. Telegram, in its standard chats, uses client-server encryption . This doesn't mean it's insecure; data is encrypted during transmission and securely stored in data centers distributed across various legal jurisdictions to prevent any single government from accessing the information.
Telegram implements 256-bit AES encryption , 2048-bit RSA encryption, and Diffie-Hellman key exchange. For those seeking the highest level of privacy, the platform has created a separate feature: Secret Chats.
What is a secret Telegram chat
A secret chat is a special conversation that uses end-to-end encryption . Unlike regular chats, these are not stored in the Telegram cloud. The content is sent directly from one device to another, ensuring that no one , not even Telegram itself, can read the messages.
A key feature is that secret chats are linked to the device where they originated. If you start a secret chat on your Android phone, you won't be able to see it or continue the conversation on your computer or tablet. If you log out of the device hosting the secret chat, you'll permanently lose access to those messages, as there's no backup on the server.
Furthermore, it's important to clarify that secret chats are strictly one-on-one conversations between two people. It's not possible to create secret groups; Telegram's end-to-end encryption features are designed exclusively for one-on-one chats.
Key differences and advanced privacy features
Although encryption may seem to be the only thing that differentiates them, secret chats offer control tools that are not present in normal chats or other conventional messaging applications.
Message self-destruction
One of the most powerful features is the self-destruct timer . This option allows messages, multimedia files, and documents to be automatically deleted from both devices once the recipient has read them and the set time has elapsed.
The timer starts counting the moment the recipient opens the message (when the two read checkmarks appear). The available time options are extremely flexible:
- OffMessages remain until they are manually deleted.
- Short times: From 1 second to 15 seconds.
- Average times: 30 seconds, 1 minute or 1 hour.
- Long times: 1 day or 1 week.
For photos and videos , Telegram blurs the preview. The timer only activates when the user taps the file to view it full screen, displaying an animation that indicates the remaining time.
Screenshot and forwarding control
To prevent confidential information from leaving the chat, Telegram implements strict restrictions. Depending on the operating system version, the application may block the ability to take screenshots . In cases where the operating system allows it, Telegram will send an immediate notification to the sender informing them that a screenshot has been taken.
Furthermore, in secret chats, forwarding messages to other contacts or groups is strictly prohibited. This restriction ensures that the chain of custody of the information remains closed between the two participants.
The Visual Encryption Key
For more cautious users, Telegram allows you to verify the encryption key . By accessing the information in the secret chat, you can view a graphical representation (an image) and a text code. If both users compare their screens and the images are identical, there is technical certainty that there is no man-in-the-middle attack and that the communication is 100% private.
How to create a secret Telegram chat step by step
There are two main ways to start these types of conversations from the mobile app:
- From the contact list: We tap the new message icon (pencil), we select the option New secret chat and then we choose the desired contact.
- From an existing chatWe open a normal conversation with the person, we click on their profile picture or name At the top, we select the button of More (three points vertically) and we choose Start secret chat.
Once created, you'll see a new conversation appear in your chat list, identified by a lock icon next to the contact's name. You can simultaneously have a regular chat and a secret chat with the same person, or even pin Telegram chats to keep them readily accessible.
How to delete or cancel a secret chat
If you wish to end an encrypted conversation, the process varies slightly depending on the platform:
- On Android: Tap and hold the secret chat in the main list and select the icon of delete (trash can) in the top bar.
- On iOSSwipe left on the secret chat and tap the delete option.
It is essential to know that, when deleting a secret chat, Telegram offers the option to delete the history for both parties , thus removing any trace of the conversation on both devices.
Telegram Platforms and Compatibility
Telegram stands out for its versatility. It's available on Android, iOS, Windows, macOS, and Linux , and also has a web browser version.
One interesting aspect is that Telegram has an open API , which allows the community to develop third-party applications. These applications, while not official, often offer additional features and are supported by the company's open philosophy.
For desktop users, there are portable versions that don't require installation. This allows you to carry the application on a USB drive and access cloud chats from any computer without leaving any trace on the host computer's operating system.
Considerations regarding safety and parental control
While privacy is an advantage, the anonymity and self-destruction of secret chats pose a challenge to children's safety. Parents should be aware that it is not possible to trace the content of a secret chat once the messages have self-destructed.
To mitigate risks, it is recommended to enable two-step verification (Settings > Privacy and security), which adds a mandatory password in addition to the SMS code. It is also advisable to set up a passcode to lock the entire application using a PIN, fingerprint, or facial recognition.
It is important to remember that no application can protect the user if the device is rooted or jailbroken , as this allows malicious software to access system memory and read messages before or after they are encrypted.
Telegram presents itself as a well-rounded tool that offers the convenience of the cloud for everyday use and an impenetrable digital fortress for those handling sensitive information. By mastering the use of secret chats, the self-destruct timer, and end-to-end encryption, users gain complete control over their identity and data online.
