Some tips to help protect privacy on Zalo

Here are some important privacy and security features that Zalo has researched, updated and provided to users.

The Self-Deleting Messages feature on Zalo helps users protect their privacy to the maximum.

In Vietnam, there are more than 74 million users using the Zalo communication application. In relative comparison, Vietnam's population is 99.46 million people (according to data in December 2022), so it is estimated that the number of users of this "made in Vietnam" messaging platform accounts for more than 74% of our country's population. However, many people may not know how to use Zalo's features properly to protect themselves when exchanging information.

Below are some important privacy and security features when using Zalo.

Self-deleting messages

The Self-Deleting Messages feature on Zalo is one of the privacy protection methods that users prefer. With this feature, users can proactively protect the privacy of important conversations with messages that automatically delete after 1, 7 or 30 days according to personal needs. After enabling this feature, the countdown clock below each message in the conversation will remind users of the importance of the information being exchanged.

As someone who cares about privacy on the internet, Mr. Nguyen Tuan (HCMC) said: “I only need to exchange important information for a certain period of time, then I will withdraw it. With Zalo's self-deleting message feature, I just need to turn it on without having to spend time manually withdrawing each content. It saves time and gives me complete peace of mind.”

Self-deleted messages will be permanently deleted and cannot be recovered even if the feature is turned off. This feature is also developed on both mobile and computer versions.

Leave the group without disturbing other members

Privacy features are popular with users.

This feature allows users to leave messaging groups on Zalo without notifying other members. Allows leaving the group while blocking others from inviting you again, strangers will not be able to directly add you to the group but must send an invitation and wait for acceptance.

According to statistics, the feature of blocking strangers from adding to groups is popular and frequently set up by many users. This is a common situation when using messaging applications.

In addition, to minimize annoying messages or to protect personal information, users can set "Block viewing logs" or "Block strangers from texting/calling"... in Settings -> Privacy.

In addition to ensuring maximum user privacy, Zalo also invests in security to help users feel secure when using this platform.

E2EE End-to-End Encryption

With E2EE encryption, only the sender and recipient devices can read the contents of the message.

E2EE (End-to-End Encryption) - end-to-end encryption is simply understood as an encryption method in which only the sender and recipient can read the message being sent. This encryption method ensures that even if a hacker intentionally attacks the message stream, the user's sent content will not be read.

Through E2EE, all Zalo message formats (text, images, videos , files...) are encoded into random, meaningless character strings and can only be decoded directly on the recipient's device.

This feature was built and developed by Zalo based on the open source protocol Signal Protocol. This is an international protocol used by most of the world's leading messaging applications for E2EE. Many prestigious global technology experts have also tested and guaranteed the quality and security of Signal Protocol over the years.

When a user sends a message, the content is immediately encoded into characters, for example “axP/Hn8hkhs-u10smIytTT=QQ”. The code is then kept intact throughout the transmission process, and is only decode into the original content when it reaches the recipient’s device. This feature is currently being applied to personal messages. With a maximum of 10 people in a chat group, Zalo is testing and opening the limit for some trial users.

To set up chat encryption on Zalo, users just need to click on the “Settings” section on the application and select the “End-to-end encryption” upgrade. Up to now, E2EE can be used for both mobile and computer versions.

Account Security

Zalo's advanced security features help users feel secure when exchanging information.

To ensure the best security for your account, users should regularly check their applications.

- Manage login devices: This feature allows you to view your login history, and supports logging out of secondary devices or untrusted devices. To use this feature, users go to “Account Protection” and check the information.

- 2-layer security: Helps users increase account protection by requiring mobile device confirmation every time they log in on a new computer.

- Lock Zalo app: Requires code entry every time the app is opened.

It can be said that the need for online communication via messaging applications in general and Zalo in particular has become indispensable in work and daily life. Therefore, updating and monitoring features to protect privacy and security regularly is extremely important in cyberspace.
