Today, there is hardly a single person who does not use messengers. WhatsApp alone is installed on hundreds of millions of devices around the world and processes a total of tens of billions of messages daily. We will take a look at the best instant messengers that provide a high level of security.

Telegram

This messenger was included on the list of the most reliable apps because of the unique encryption technology of secret chats. Telegram uses its end-to-end encryption protocol when all messages are encrypted on the sender’s gadget and decrypted on the recipient’s gadget. This technology is only implemented for secret chats, and normal messages can theoretically be intercepted.

Hacking Telegram is difficult: for this, the attacker will have to create a copy of the SIM card and gain access to the application or use dummies. However, with due care, Telegram communications will be protected.

Threema

The creation of the messenger was a consequence of the growing concern of users about the security and privacy of correspondence. The developers of this messenger took into account all the wishes of users, so Threema quickly gained popularity:

• Threema is not linked to a phone number, which makes it much more difficult to identify a person using the messenger.
• You can register in the messenger anonymously, and messages are encrypted on the user’s devices.
• The application has a trust rating: to start a dialogue with a user, you must enter his identifier.
• Encryption of each individual chat with a PIN-code is provided.

In terms of security, Threema is one of the most reliable messengers out there. It is impossible to get legal access to your correspondence in any way, and even if your phone falls into the wrong hands, the functions of encoding messages with a PIN code and temporarily deleting messages will reliably protect information. Moreover, after 10 unsuccessful attempts to enter a secret word, all data in the application will be erased.

FaceTime

Apple uses end-to-end encryption to protect data during its transfer between two devices, so it is pointless to intercept closed packets along the way, as it will be extremely problematic to decrypt them. E2EE only loses its relevance if your smartphone is stolen.

However, it can always be blocked through a special application. Calls are not recorded or stored on the company’s servers. Even US government agencies cannot access them, which has led to repeated claims against Apple.

FaceTime is not easy to hack, and it protects users’ personal information. All messages on Apple devices are encrypted, so they can’t be read without your password. You can set up automatic deletion of your correspondence after 30 days.

The popularity of instant messengers brings to life one of the main problems of the modern Internet: the problem of confidentiality of messages. The idea that someone else is reading the correspondence in the messenger may seem absurd, given the amount of information we share every day. That is why it is important to trust only messengers that provide a high level of confidentiality.
