Created as an alternative to WhatsApp and Facebook Messenger, Telegram is a social network that has been growing exponentially with groups and communities of different themes. Currently, more than 700 million people use the application, and you’ve probably already registered on the network. But, is your profile protected? In this article, we will show you how to do 2-factor authentication on Telegram.

What is Telegram?

Telegram is a Russian social network whose purpose is instant messaging. Through the App, users can send text messages, audio, videos, photos, stickers, and much more. In addition, you can also make video calls and much more. The service has a mobile and desktop version. The platform is compatible with Windows, MacOS, and Linux, but can also be used directly in the browser.

The App grows every day, gaining new users and becoming one of WhatsApp’s biggest competitors. One of its main differentials is the creation of groups of up to 20,000 members, which favors the creation of large communities with varied purposes. Currently, the platform is widely used as a marketing strategy to generate connections between brands and their users.

In addition, it is also very common to create groups for studies and work, and groups for discussions of varied content such as series, movies, books, and other subjects. Another advantage of Telegram is sending files of unlimited size over the network.

Registration is done by phone number. After providing this data, the social network verifies the number, giving access to the App and displaying the contacts already registered on the platform.

Security on Telegram

A big highlight of Telegram is its security. Made with end-to-end encryption, the network prevents messages sent by the user from being intercepted by anyone.

Another feature that ensures user privacy is secret chats. In these conversations, participants can configure the platform to delete messages a few seconds after sending them. This happens because secret chats use end-to-end encryption, which only allows access to the conversation from the participants’ devices, being inaccessible to third parties, including Telegram developers.

In addition, Telegram has a cloud storage technology, which causes messages to be stored on an encrypted server, not on users’ devices. Therefore, the platform gives even more privacy to its members.

The commitment not to disclose data to third parties is also one of the differentials that make the social network a safe platform for its users.

Why enable 2-factor authentication?

After reading about so many advantages that guarantee Telegram security, you must be wondering if it is really necessary to perform actions such as activating 2-factor verification.

The truth is that, as much as platforms take care of data security and privacy, we are still susceptible to scams and cyber attacks. That’s why it’s important that we protect our account information at all times.

2-factor authentication is a feature that consists of linking your access to a second factor, which can be an email, SMS, PIN, biometrics, secret answers, or other means. In this way, when logging in, the platform sends an access request with a numeric code through the path chosen for authentication.

This makes third-party access difficult since it is unlikely that other people would have access to both access information simultaneously. Next, we’ll teach you how to activate 2-factor authentication on Telegram.

How to activate 2-factor authentication on Telegram?

To activate 2-factor authentication on Telegram, just click on the settings tab, select the “Privacy and Security” option, and then click on “Two-Step Verification“.
