Viber is one of the most popular messaging apps in the world, with over a billion registered users. It offers a range of features, including text messaging, voice and video calls, and file sharing. However, with the rise of cybercrime and data breaches, users are becoming increasingly concerned about the safety and security of their online communications. In this article, we will delve into the security features of Viber chat and explore how safe it is to use.
End-to-End Encryption: The Foundation of Viber’s Security
Viber uses end-to-end encryption to protect user communications. This means that only the sender and the recipient can read the messages, and no one else, including Viber itself, can intercept or access them. End-to-end encryption is a widely accepted security standard, and it is used by many popular messaging apps, including WhatsApp and Signal.
Viber’s end-to-end encryption is based on the Signal Protocol, which is a widely respected and reviewed encryption protocol. The Signal Protocol uses a combination of symmetric and asymmetric encryption to ensure that messages are both confidential and authentic. Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys, one for encryption and another for decryption.
How Viber’s End-to-End Encryption Works
Here’s a step-by-step explanation of how Viber’s end-to-end encryption works:
- When a user sends a message, Viber’s app generates a random encryption key.
- The encryption key is used to encrypt the message, making it unreadable to anyone except the intended recipient.
- The encrypted message is then sent to Viber’s servers, which forward it to the recipient’s device.
- The recipient’s device decrypts the message using the same encryption key, making it readable again.
Additional Security Features
In addition to end-to-end encryption, Viber offers several other security features to protect user communications. These include:
Two-Step Verification
Two-step verification is a security feature that requires users to provide a second form of verification, in addition to their password, to access their account. This adds an extra layer of security, making it more difficult for hackers to gain unauthorized access to user accounts.
Screen Lock
Viber’s screen lock feature allows users to lock their app with a PIN or password, preventing unauthorized access to their conversations.
Hidden Chats
Viber’s hidden chats feature allows users to hide specific conversations from their chat list, making it more difficult for others to access them.
Message Deletion
Viber’s message deletion feature allows users to delete messages from their conversations, both on their device and on the recipient’s device.
Viber’s Security Record
While Viber has a strong set of security features, its security record is not without blemishes. In 2013, Viber was criticized for its lack of transparency and security, with some experts accusing the company of using weak encryption and storing user data in plain text.
However, since then, Viber has made significant improvements to its security, including the introduction of end-to-end encryption and two-step verification. In 2016, Viber was awarded a score of 6 out of 7 by the Electronic Frontier Foundation (EFF), a non-profit organization that advocates for digital rights and freedoms.
Comparison with Other Messaging Apps
Viber is not the only messaging app that offers end-to-end encryption and other security features. Other popular messaging apps, such as WhatsApp and Signal, also offer similar security features.
Here’s a comparison of Viber’s security features with those of WhatsApp and Signal:
| App | End-to-End Encryption | Two-Step Verification | Screen Lock | Hidden Chats | Message Deletion |
| — | — | — | — | — | — |
| Viber | Yes | Yes | Yes | Yes | Yes |
| WhatsApp | Yes | Yes | Yes | No | Yes |
| Signal | Yes | Yes | Yes | No | Yes |
Conclusion
Viber chat is a safe and secure messaging app that offers a range of security features, including end-to-end encryption, two-step verification, and screen lock. While its security record is not without blemishes, Viber has made significant improvements in recent years, and it is now considered one of the most secure messaging apps available.
However, as with any online communication, there are risks involved, and users should always be cautious when sharing sensitive information online. By following best practices, such as using strong passwords and being careful when clicking on links, users can minimize the risks and enjoy a safe and secure messaging experience with Viber.

Is Viber Chat End-to-End Encrypted?
Viber chat does offer end-to-end encryption for its users. This means that only the sender and the recipient can read the messages, and no one in between, including Viber itself, can intercept or access the conversation. This level of encryption is based on the Signal Protocol, which is widely regarded as one of the most secure encryption protocols available.
However, it’s essential to note that end-to-end encryption is only enabled when both parties have the latest version of Viber installed on their devices. Additionally, users can verify the encryption status by checking the color of the lock icon in the chat window. A green lock indicates that the conversation is end-to-end encrypted, while a gray lock means that the encryption is not enabled.
Does Viber Store Chat History on Its Servers?
Viber does store some metadata related to chat history on its servers, but the actual content of the messages is not stored. This means that Viber can access information such as the sender’s and recipient’s phone numbers, the timestamp of the message, and the type of message (e.g., text, image, or video). However, the company claims that it does not store the actual content of the messages, and therefore, it cannot access or share it with third parties.
It’s worth noting that Viber’s servers are located in various countries around the world, which may be subject to different data protection laws and regulations. While Viber claims to comply with the General Data Protection Regulation (GDPR) in the European Union, users should be aware that their data may be stored in countries with less stringent data protection laws.
Can Viber Read or Share My Messages?
Viber claims that it cannot read or share users’ messages, thanks to its end-to-end encryption. As mentioned earlier, only the sender and the recipient can access the content of the messages, and Viber itself does not have the decryption keys. This means that even if Viber is requested to provide message content to law enforcement or other third parties, it will not be able to do so.
However, Viber may share some metadata related to chat history, such as the sender’s and recipient’s phone numbers, with third parties in certain circumstances. For example, Viber may share this information with law enforcement agencies if it receives a valid court order or subpoena. Users should be aware of these possibilities and take necessary precautions to protect their privacy.
How Secure Are Viber’s File Transfers?
Viber’s file transfers are also end-to-end encrypted, which means that only the sender and the recipient can access the files. This applies to all types of files, including images, videos, and documents. Viber uses the same encryption protocol as for text messages, ensuring that files are protected from interception or eavesdropping.
However, users should be cautious when sharing files with others, especially if they contain sensitive information. It’s essential to verify the identity of the recipient and ensure that they are trustworthy. Additionally, users should be aware that files may be stored on their device or the recipient’s device, which may not be secure if the device is compromised or accessed by unauthorized parties.
Can I Trust Viber’s Screen Sharing Feature?
Viber’s screen sharing feature allows users to share their screen with others in real-time. This feature is also end-to-end encrypted, which means that only the sender and the recipient can access the shared screen. However, users should be aware that screen sharing can pose some security risks, especially if they are sharing sensitive information or accessing confidential data.
To use Viber’s screen sharing feature securely, users should ensure that they are sharing their screen with trusted individuals only. They should also be cautious when accessing sensitive information or confidential data during screen sharing, as the recipient may be able to capture or record the shared screen. Additionally, users should be aware that screen sharing may consume more data and battery power than regular messaging.
How Does Viber Protect Against Spam and Phishing?
Viber has implemented various measures to protect its users against spam and phishing. For example, the app uses machine learning algorithms to detect and block suspicious messages, including those that contain malware or phishing links. Viber also allows users to report spam messages, which helps to improve the app’s spam detection capabilities.
However, users should still be cautious when receiving messages from unknown senders or clicking on links from unfamiliar sources. They should verify the identity of the sender and ensure that the link is legitimate before clicking on it. Additionally, users should keep their Viber app up to date, as newer versions often include improved security features and bug fixes.
Is Viber Compliant with Data Protection Regulations?
Viber claims to comply with various data protection regulations, including the General Data Protection Regulation (GDPR) in the European Union. The company has implemented measures to ensure that users’ data is protected, including end-to-end encryption, secure data storage, and access controls.
However, users should be aware that Viber’s data protection practices may vary depending on their location and the specific laws and regulations that apply. For example, users in the European Union may have more stringent data protection rights than users in other regions. Users should review Viber’s privacy policy and terms of service to understand how their data is protected and what rights they have.
